| 101 | NB : Banners are a CUPS only feature for now. |
---|
[1154] | 102 | |
---|
| 103 | Administration : |
---|
| 104 | |
---|
| 105 | - Powerful administration tools can be used to |

[1154] | 117 | |
---|
| 118 | - Quota report generator available either from the |
---|
| 119 | command line or in any web browser. |
---|
| 120 | The web-based quota report generator can be |
---|
| 121 | user/password protected. |
---|
| 122 | |
---|
| 123 | - Print quote generator can tell users how much |
---|
| 124 | a print job will cost them in advance. |
---|
| 125 | |
---|
| 126 | - Policy with regard to unregistered users can |
---|
| 127 | be configured for each printer to either deny |

| 135 | - Warning and error messages' content is completely |
---|
| 136 | configurable. |
---|
| 137 | |
---|
| 138 | - Configuration can be changed without needing to |
---|
| 139 | restart the printing system. |
---|
[739] | 140 | |
---|
[1154] | 141 | - Complete print job history is kept. This can be |
---|
| 142 | disabled if needed. |
---|
| 143 | |
---|
| 144 | - Automated low quota or balance remainder can be |
---|
| 145 | scheduled regularly or launched manually. |
---|
| 146 | |
---|
[1744] | 147 | - Powerful data dumper to export datas to other |
---|
[1804] | 148 | software (spreadsheets for example). Actually |
---|
| 149 | supported formats are : |
---|
[1744] | 150 | |
---|
[1804] | 151 | - Comma separated values ; |
---|

[1155] | 159 | User Interface : |
---|
| 160 | |
---|
[1154] | 161 | - All the command line tools accept the -h | --help |
---|
| 162 | command line option which prints all the available |
---|
| 163 | options and show usage examples. |
---|
[1155] | 164 | |
---|
| 165 | - Completely internationalized. Actually supports the |
---|
[1648] | 166 | English, French, Spanish, Portuguese, Brasilian, Swedish, |
---|
[1945] | 167 | Thai, Greek, German, Italian, Norwegian (Bokm� and |
---|
| 168 | Turkish languages. |
---|
[1891] | 169 | More to come. |
---|
[1154] | 170 | |
---|
| 171 | ==================================================================== |
---|
| 172 | |
---|
[739] | 173 | Planned features are described in the TODO file. |
---|
| 174 | |
---|
[1507] | 175 | Actually two (or an infinity of) page accounting methods are |
---|
[980] | 176 | implemented : |
---|
[695] | 177 | |
---|
[1475] | 178 | - The 'hardware' method consists in querying the printer (via SNMP |
---|
[1181] | 179 | or Netatalk or any other method of your choice) for its total pages |
---|
[1186] | 180 | counter. |
---|
[980] | 181 | |
---|
[1600] | 182 | This is done both at the beginning and at the end of a |
---|
[1186] | 183 | print job. The counters difference is then immediately used to |
---|
| 184 | decrease the user's account balance or increase his quota usage. |
---|
| 185 | |
---|
[1475] | 186 | - The 'software' method consists in delegating the computation of the |
---|
[980] | 187 | job's size in number of pages to any external command of your choice. |
---|
| 188 | The command can read the job's data from its standard input and MUST |
---|
[1186] | 189 | output the job's size on its standard output. Changes to the user |
---|
[1600] | 190 | account are reported immediately. |
---|
[980] | 191 | |
---|
[1600] | 192 | PyKota is known to work fine with most laser printers, either with |
---|
| 193 | software accounting, or with hardware accounting if the printer |
---|
| 194 | supports this. |
---|
[724] | 195 | |
---|
[695] | 196 | ============================================================ |
---|
| 197 | |
---|
| 198 | INSTALLATION: |
---|
| 199 | ============= |
---|
| 200 | |
---|
[1186] | 201 | NB : |
---|
| 202 | ==== |
---|
[887] | 203 | |
---|
[1397] | 204 | You may learn more about PyKota, if it fits your own organization, |
---|
| 205 | its internal working, and some potential performance drawbacks and |
---|
| 206 | how to avoid them, in a WiKi administered by Ryan Suarez at : |
---|

---|
| 214 | This document, written in Spanish by Sergio Gonzalez Gonzalez, |
---|
| 215 | describes the integration of PyKota into an OpenLDAP + Samba |
---|
| 216 | + CUPS installation. Even for people who can't read spanish |
---|
| 217 | this document is really interesting, and contains lots of |
---|
| 218 | screenshots. |

[1951] | 220 | Finally, SuSe users may find the following document to best describe |
---|
| 221 | how to install PyKota on their favorite distribution. It's a Spanish |

---|
| 223 | |
---|
| 224 | http://www.cvr.espol.edu.ec/people/dennis/Pykota1.19-SuSE9.1.pdf |
---|
| 225 | |
---|
| 226 | |
---|
[714] | 227 | Prerequisite : |
---|
| 228 | -------------- |
---|
| 229 | |
---|
| 230 | You need to have the following tools installed on the CUPS Server : |
---|
| 231 | |
---|
[1886] | 232 | - CUPS (http://www.cups.org) or LPRng (http://www.lprng.com) |
---|
| 233 | - Python v2.1 or above (http://www.python.org) |
---|
| 234 | - eGenix' mxDateTime Python extension (http://www.egenix.com) |
---|
[1771] | 235 | - The JAXML Python module to be able to dump datas in the XML format. |
---|
[1886] | 236 | (http://www.librelogiciel.com/software/) |
---|
[1771] | 237 | - The Python-SNMP module to query printers for their page counter. |
---|
[1886] | 238 | (http://pysnmp.sourceforge.net) |
---|
[1771] | 239 | - The Python-OSD module to use the graphical print quota reminder. |
---|
| 240 | - SNMP tools (specifically the snmpget command) if you prefer to |
---|
| 241 | use your own script to request query printers. |
---|
[919] | 242 | - Netatalk (specifically the pap command) if you plan to |
---|
| 243 | request your printer's lifetime page counter via AppleTalk. |
---|
[1886] | 244 | (http://netatalk.sourceforge.net) |
---|
[1927] | 245 | - The ReportLab Python module (http://www.reportlab.org) if you want |
---|
| 246 | to have PyKota generate nice banners for you. |
---|
| 247 | - The Python Imaging Library (aka PIL) module |
---|
| 248 | (http://www.pythonware.com/downloads) if you want to have PyKota |
---|
| 249 | generate nice banners for you. |
---|
[1043] | 250 | - PostgreSQL's PygreSQL Python extension and the PostgreSQL client |
---|
| 251 | libraries if you plan to use PostgreSQL as the Quota Storage |
---|
| 252 | backend. |
---|
[1886] | 253 | (http://www.postgresql.org and http://www.pygreql.org) |
---|
[1043] | 254 | or |
---|
| 255 | - python-ldap Python module and the OpenLDAP client libraries |
---|
[1823] | 256 | if you plan to use an LDAP server as the Quota Storage backend. |
---|
[1886] | 257 | (http://www.openldap.org and http://python-ldap.sourceforge.net) |
---|
[714] | 258 | |
---|
[1771] | 259 | On Intel i386 architecture, and for performance reasons, it is |
---|
| 260 | strongly suggested that you install the Python accelerator Psyco, |
---|
| 261 | available at : |
---|
[1570] | 262 | |
---|
| 263 | http://psyco.sourceforge.net |
---|
| 264 | |
---|
[1571] | 265 | Under Debian : |
---|
| 266 | |
---|
| 267 | $ apt-get install python-psyco |
---|
| 268 | |
---|
| 269 | Other architectures may be supported as well in the future, check |
---|
[1600] | 270 | this on Psyco's website. |
---|
[1571] | 271 | |
---|
[1578] | 272 | Installing Psyco is not mandatory, but it will speedup PCL5 parsing |
---|
[1570] | 273 | by almost 3 times. PostScript and PDF parsing can also benefit, |
---|
| 274 | but in an almost unnoticeable manner since this part of the code |
---|
[1575] | 275 | is already optimal. For PCL5 this is a completely different matter, |
---|
[1570] | 276 | and if you install Psyco you will never regret it ! |
---|
[1600] | 277 | Same remark applies for PCL6 (aka PCLXL) : the parser is completely |
---|
| 278 | different, but the performance gain with Psyco is impressive. |
---|
[1570] | 279 | |
---|
[1186] | 280 | You may also benefit from having the following tools installed to |
---|
| 281 | deal with some printers : |
---|
| 282 | |
---|
| 283 | - npadmin |
---|
| 284 | - netcat |
---|
| 285 | - ghostscript |
---|
| 286 | |
---|
[714] | 287 | You need to have the following tools installed on the Quota Storage |
---|
| 288 | Server : |
---|
| 289 | |
---|
[1886] | 290 | - PostgreSQL (http://www.postgresql.org) |
---|
[714] | 291 | |
---|
[1043] | 292 | or |
---|
| 293 | |
---|
[1886] | 294 | - OpenLDAP, or any other LDAP server (http://www.openldap.org) |
---|
[1043] | 295 | |
---|
[1086] | 296 | NB : |
---|
| 297 | |
---|
| 298 | PygreSQL must be linked with the PostgreSQL client libraries on |
---|
| 299 | the Print Server. The PostgreSQL client libraries' version must |
---|
| 300 | match the PostgreSQL version used on the Quota Storage Server. |
---|
[714] | 301 | |
---|
[1043] | 302 | or |
---|
| 303 | |
---|
[1086] | 304 | python-ldap must be linked with the OpenLDAP client libraries on the |
---|
[1823] | 305 | Print Server. The OpenLDAP client libraries' version should match the |
---|
| 306 | OpenLDAP version used on the Quota Storage Server, if applicable. |
---|
[1043] | 307 | |
---|
[714] | 308 | This list of prerequisite software may change in the future, when |
---|
| 309 | PyKota will support more functionnalities you will be given |
---|
| 310 | alternatives. |
---|
| 311 | |
---|
[952] | 312 | Of course the Print Server and the Quota Storage Server can be the |
---|
[851] | 313 | very same machine if you've got a tiny network, or you can have |
---|
[952] | 314 | multiple Print Servers all storing their quotas on the same Quota |
---|
[851] | 315 | Storage Server if you've got a bigger network. |
---|
| 316 | |
---|
[1886] | 317 | Hint : |
---|
| 318 | ------ |
---|
| 319 | |
---|
| 320 | - The Debian GNU/Linux distribution is to our knowledge the |
---|
| 321 | easiest distribution to install PyKota on, because all |
---|
| 322 | of PyKota dependencies are already included, excepted |
---|
| 323 | for the PySNMP (http://pysnmp.sourceforge.net) module |
---|
| 324 | which for now has to be downloaded separately. |
---|
| 325 | |
---|
[714] | 326 | Then : |
---|
| 327 | ------ |
---|
| 328 | |
---|
[724] | 329 | Download the latest PyKota version from the CVS tree on : |
---|
[695] | 330 | |
---|
[725] | 331 | http://savannah.nongnu.org/projects/pykota |
---|
[695] | 332 | |
---|
[1906] | 333 | You can now check if the dependencies are correct by typing : |
---|
[695] | 334 | |
---|
[1906] | 335 | python checkdeps.py |
---|
| 336 | |
---|
| 337 | To install the software, just type : |
---|
| 338 | |
---|
[725] | 339 | python setup.py install |
---|
[695] | 340 | |
---|
| 341 | You may need to be logged in with sufficient privileges (e.g. root) |
---|
| 342 | |
---|
| 343 | Go to the initscripts subdirectory of PyKota's sources, and choose |
---|
[1600] | 344 | the appropriate storage backend for your configuration. Read carefully |
---|
[695] | 345 | the associated README file and execute the initialization script |
---|
[878] | 346 | to create an empty PyKota Storage. Upgrade scripts may be |
---|
| 347 | provided as well. |
---|
[695] | 348 | |
---|
[1186] | 349 | Copy the conf/pykota.conf.sample and conf/pykotadmin.conf.sample |
---|
[1107] | 350 | sample configuration files to /etc/pykota/pykota.conf and |
---|
[1905] | 351 | /etc/pykota/pykotadmin.conf |
---|
| 352 | The installation script usually copies these files into /usr/share/pykota |
---|
[1198] | 353 | |
---|
[1905] | 354 | You need to adapt these files to your own needs. Especially you may |
---|
| 355 | have to create sections named after your own printers, and change |
---|
| 356 | the administrator's email address which by default is |
---|
| 357 | root@localhost. Read and try to understand these two very well |
---|
| 358 | commented files, so that you'll encounter less problems later. |
---|
| 359 | |
---|
[1198] | 360 | Also be sure to double check that commands that query printers |
---|
[1186] | 361 | for their internal page counter work from the command line |
---|
| 362 | before using them in PyKota's configuration. |
---|
[695] | 363 | |
---|
[1186] | 364 | The rest of the installation depends on your printing system : |
---|
| 365 | |
---|
[1185] | 366 | - CUPS Printing System : |
---|
[952] | 367 | |
---|
[1185] | 368 | Once and for all : |
---|
[952] | 369 | |
---|
[1185] | 370 | Create a symbolic link to the cupspykota backend |
---|
| 371 | in CUPS's backend directory : |
---|
| 372 | |
---|
| 373 | $ cd /usr/lib/cups/backend |
---|
[1345] | 374 | $ ln -s /usr/share/pykota/cupspykota cupspykota |
---|
[1185] | 375 | |
---|
| 376 | Restart CUPS so that the new backend can be detected. |
---|
| 377 | |
---|
| 378 | $ /etc/init.d/cupsys restart |
---|
| 379 | |
---|
[1600] | 380 | or : |
---|
| 381 | |
---|
| 382 | $ /etc/rc.d/init.d/cupsysrestart |
---|
| 383 | |
---|
| 384 | or any similar command depending on your operating system. |
---|
| 385 | |
---|
[1185] | 386 | For new printers : |
---|
[952] | 387 | |
---|
[1185] | 388 | Go to CUPS management interface (http://localhost:631) |
---|
| 389 | and choose the appropriate PyKota managed device depending |
---|
| 390 | on the type of printer you use. For example, if your |
---|
| 391 | printer is waiting on : |
---|
| 392 | |
---|
[1354] | 393 | socket://myprinter.example.com:9100 |
---|
[1185] | 394 | |
---|
| 395 | Then choose : |
---|
| 396 | |
---|
[1354] | 397 | cupspykota:socket://myprinter.example.com:9100 |
---|
[1185] | 398 | |
---|
| 399 | Configure your printer as usual. |
---|
| 400 | |
---|
[1186] | 401 | Now double check /etc/pykota/pykota.conf |
---|
[1600] | 402 | |
---|
| 403 | You should manually create a section named after the |
---|
[1402] | 404 | printer you've just added, unless you have set |
---|
| 405 | all options globally. |
---|
[1600] | 406 | |
---|
[1408] | 407 | The new pkhint command can help you with correct settings |
---|
| 408 | for your printers, but don't rely on it because it is still |
---|
[1600] | 409 | experimental work. To use pkhint, you have to feed it with |
---|
| 410 | CUPS' printers.conf file this way : |
---|
[1186] | 411 | |
---|
[1600] | 412 | $ pkhint </etc/cups/printers.conf |
---|
| 413 | |
---|
| 414 | pkhint will try to tell you what is the best accounting |
---|
| 415 | method for each printer and will print some lines you'll |
---|
| 416 | just have to copy&paste in the appropriate sections in |
---|
| 417 | /etc/pykota/pykota.conf |
---|
| 418 | |
---|
[1185] | 419 | That's all. |
---|
[952] | 420 | |
---|
[1185] | 421 | For existing printers : |
---|
| 422 | |
---|
[1186] | 423 | If you had already installed a version of PyKota earlier |
---|
| 424 | than 1.16alpha7, then remove the *cupsFilter lines in your |
---|
| 425 | PPD files for each printer already managed printers. Each |
---|
| 426 | line to remove is of the form : |
---|
[1185] | 427 | |
---|
[1345] | 428 | *cupsFilter: "application/vnd.cups-postscript 0 /usr/share/pykota/pykota" |
---|
[1185] | 429 | |
---|
[1345] | 430 | This means that each time the pstops filter will be executed, it will |
---|
| 431 | pass the job's data through the pykota filter which is present in |
---|
| 432 | /usr/share/pykota |
---|
| 433 | |
---|
[1185] | 434 | Don't touch anything else, especially any other *cupsFilter line. |
---|
[1186] | 435 | Then save each of these files. |
---|
[1185] | 436 | |
---|
| 437 | Then, the easiest is to directly modify the DeviceURI lines |
---|
| 438 | in /etc/cups/printers.conf, you just have to put |
---|
| 439 | 'cupspykota:' in front of what is already on these lines. |
---|
| 440 | For example, replace : |
---|
| 441 | |
---|
[1354] | 442 | DeviceURI socket://myprinter.example.com:9100 |
---|
[1185] | 443 | |
---|
| 444 | with : |
---|
| 445 | |
---|
[1354] | 446 | DeviceURI cupspykota:socket://myprinter.example.com:9100 |
---|
[1345] | 447 | |
---|
| 448 | or : |
---|
[1185] | 449 | |
---|
[1354] | 450 | DeviceURI cupspykota://socket://myprinter.example.com:9100 |
---|
[1345] | 451 | |
---|
[1185] | 452 | Save the file and restart CUPS. |
---|
[1600] | 453 | |
---|
| 454 | Here too, you may find it interesting to use the pkhint command as |
---|
| 455 | described above to help with manual configuration of the file |
---|
| 456 | /etc/pykota/pykota.conf |
---|
[695] | 457 | |
---|
[1185] | 458 | - LPRng Printing System : |
---|
[952] | 459 | |
---|
[1600] | 460 | For each printer on which you want to use PyKota : |
---|
| 461 | |
---|
| 462 | Modify the printer's entry in /etc/printcap : you have to add |
---|
| 463 | the three following lines : |
---|
| 464 | |
---|
[1612] | 465 | :achk=true:\ |
---|
[1600] | 466 | :as=/usr/share/pykota/lprngpykota:\ |
---|
| 467 | :ae=/usr/share/pykota/lprngpykota:\ |
---|
| 468 | |
---|
| 469 | This will tell LPRng to activate accounting, and use the lprngpykota |
---|
| 470 | accounting filter both at the start and at the end of printing. |
---|
| 471 | |
---|
| 472 | When all modifications are done, just save the /etc/printcap file and |
---|
| 473 | restart LPRng : |
---|
| 474 | |
---|
| 475 | $ /etc/init.d/lprng restart |
---|
| 476 | |
---|
| 477 | or : |
---|
[1500] | 478 | |
---|
[1600] | 479 | $ /etc/rc.d/init.d/lprng restart |
---|
| 480 | |
---|
| 481 | or any similar command depending on your operating system. |
---|
| 482 | |
---|
| 483 | NB : the pkhint command can't be used with LPRng for now, so you |
---|
| 484 | have to modify /etc/pykota/pykota.conf carefully. The comments |
---|
| 485 | in this file will help you. |
---|
| 486 | |
---|
[1186] | 487 | Now you can begin to populate the PyKota's database with printers, |
---|
| 488 | users and groups : |
---|
[952] | 489 | |
---|
[716] | 490 | Add printers and users to the quota system and set their quota values : |
---|
[695] | 491 | |
---|
[1345] | 492 | Starting from version 1.18alpha2, the preferred command to manage |
---|
| 493 | printers is named pkprinters |
---|
| 494 | |
---|
| 495 | $ pkprinters --help |
---|
| 496 | |
---|
| 497 | will tell you how to create, manage or delete printers and |
---|
| 498 | printers groups. |
---|
[1402] | 499 | |
---|
| 500 | $ pkprinters --add --charge 0.05 hp2100 |
---|
| 501 | |
---|
| 502 | would add the printer named hp2100 with a price per page |
---|
| 503 | of 0.05 unit. |
---|
[1345] | 504 | |
---|
[1402] | 505 | Now set quotas for users on this printer : |
---|
| 506 | |
---|
[1086] | 507 | $ edpykota --add -P hp2100 -S 40 -H 50 user1 ... userN |
---|
[724] | 508 | |
---|
[725] | 509 | launching edpykota without any argument or with the --help |
---|
| 510 | command line option will show you all the possibilities. |
---|
[1086] | 511 | |
---|
| 512 | by default, each user is limited by "quota", this means that on |
---|
| 513 | each printer he can have a different soft and hard limit. |
---|
| 514 | You may want to limit the user by his account balance value, |
---|
[1107] | 515 | in which case, the print quota is shared between all printers |
---|
[1086] | 516 | instead of being different. To do this, use the following : |
---|
| 517 | |
---|
| 518 | $ edpykota --add -P hp2100 --limitby balance --balance 10 user1 ... userN |
---|
| 519 | |
---|
| 520 | This will put 10 $ (or Euros, PyKota doesn't care) on each user's account |
---|
| 521 | balance, and tell PyKota to limit them by their account balance value. |
---|
| 522 | Whenever they print on any printer, their account balance value is |
---|
| 523 | decreased by an amount which depends on the particular price per page |
---|
| 524 | and per job that you may have defined on the printer with edpykota's |
---|
| 525 | --charge command line option. |
---|
[1107] | 526 | Soft and Hard limits are not used if "--limitby balance" is used, |
---|
| 527 | but you can define a "poorman"'s threshold in /etc/pykota/pykota.conf |
---|
| 528 | to obtain a similar result (warning message when quota is low). |
---|
[695] | 529 | |
---|
[990] | 530 | Restart CUPS or LPRng, for example under Debian GNU/Linux systems : |
---|
[695] | 531 | |
---|
[725] | 532 | $ /etc/init.d/cupsys restart |
---|
[990] | 533 | |
---|
| 534 | or : |
---|
| 535 | |
---|
| 536 | $ /etc/init.d/lprng restart |
---|
[695] | 537 | |
---|
| 538 | Your users now should be able to print but not exceed their |
---|
| 539 | printing quota. |
---|
| 540 | |
---|
[1149] | 541 | To see printer quota usage, you can use : |
---|
[794] | 542 | |
---|
| 543 | $ repykota --printer lp |
---|
| 544 | |
---|
| 545 | or : |
---|
| 546 | |
---|
| 547 | $ repykota |
---|
| 548 | |
---|
| 549 | which will print quota usage for all users on all printers, |
---|
[1107] | 550 | along with totals, if you are the root user. If you are |
---|
| 551 | a regular user, only your own quota report will be produced. |
---|
[794] | 552 | |
---|
[1107] | 553 | Quota reports are also available remotely by using the CGI script |
---|
[1345] | 554 | printquota.cgi provided in the cgi-bin/ subdirectory. You can |
---|
| 555 | also use the CSS stylesheet present in the stylesheets/ subdirectory |
---|
[1402] | 556 | and put it at your web server's DocumentRoot, to benefit from a nicer |
---|
| 557 | look, especially quota violations will appear in different colors. |
---|

---|
| 560 | file which is part of this software. |
