| 21 | Tea4CUPS is the equivalent of the *nix command 'tee', but as a CUPS |
|---|
| 22 | backend. |
|---|
| 23 | |
|---|
| 24 | Tea4CUPS behaves just like any other CUPS backend, but allows you to |
|---|
| 25 | transparently send print jobs' datas to any number of outputs : other |
|---|
| 26 | CUPS backends, files or pipes. |
|---|
| 27 | |
|---|
| 28 | This for example allows you to output the same print job on several |
|---|
| 29 | printers at the same time, which is not possible with CUPS. |
|---|
| 30 | |
|---|
| 31 | Another possibility would be for example to send the same document to |
|---|
| 32 | a printer, a PDF generator, a Fax, and as an attachment to an email |
|---|
| 33 | message, all of this by printing it a single time. |
|---|
| 34 | |
|---|
| 35 | To help your own commands, Tea4CUPS makes available as part of the |
|---|
| 36 | environment several variables which can be used as part of the |
|---|
| 37 | commands you use : |
|---|
| 38 | |
|---|
| 39 | TEAPRINTERNAME : The print queue name. |
|---|
| 40 | TEADIRECTORY : Tea4CUPS output directory. |
|---|
| 41 | TEADATAFILE : Full name of Tea4CUPS work file (in $TEADIRECTORY). |
|---|
| 42 | TEAJOBSIZE : Job's size in bytes. |
|---|
| 43 | TEAMD5SUM : MD5 sum of the job's datas. |
|---|
| 44 | TEACLIENTHOST : Client's hostname or IP address. |
|---|
| 45 | TEAJOBID : Job's Id. |
|---|
| 46 | TEAUSERNAME : Name of the user who launched the print job. |
|---|
| 47 | TEATITLE : Job's title. |
|---|
| 48 | TEACOPIES : Number of copies requested. |
|---|
| 49 | TEAOPTIONS : Options of the print job. |
|---|
| 50 | TEAINPUTFILE : Print job's data file or empty when job read from stdin. |
|---|
| 51 | |
|---|
| 52 | In the case you want to use both Tea4CUPS and PyKota, you MUST install |
|---|
| 53 | PyKota v1.22alpha2 or higher to avoid a race condition. |

| 57 | Installation : |
|---|
| 58 | -------------- |
|---|
| 59 | |
|---|
| 60 | 0 - Download Tea4CUPS from : |
|---|
| 61 | |
|---|
| 62 | http://www.librelogiciel.com/software/Tea4CUPS/action_Presentation |
|---|
| 63 | |
|---|
| 64 | and extract it : |
|---|
| 65 | |
|---|
| 66 | $ tar -zxf tea4cups-x.yy.tar.gz |
|---|
| 67 | |
|---|
| 68 | where x.yy is Tea4CUPS' version number. |
|---|
| 69 | |
|---|
| 70 | 1 - Copy the 'tea4cups' command into CUPS' backend directory, |
|---|
| 71 | for example : |
|---|
| 72 | |
|---|
| 73 | $ cp tea4cups /usr/lib/cups/backend |
|---|
| 74 | |
|---|
| 75 | 2 - Restart CUPS in order for this new backend to be detected. |
|---|
| 76 | |
|---|
| 77 | 3 - Either from CUPS' web interface, add new printers with |
|---|
| 78 | 'Tea4CUPS managed' in front of the device's name. |
|---|
| 79 | |
|---|
| 80 | Or by directly modifying CUPS' printers.conf file, prepend |
|---|
| 81 | each DeviceURI value with 'tea4cups://', and restart CUPS. |
|---|
| 82 | |
|---|
| 83 | 4 - Copy tea4cups.conf into CUPS' configuration directory (where |
|---|
| 84 | cupsd.conf resides) : |
|---|
| 85 | |
|---|
| 86 | $ cp tea4cups.conf /etc/cups/ |
|---|
| 87 | |
|---|
| 88 | 5 - Modify tea4cups.conf to suit your needs. Several examples |
|---|
| 89 | are included. |
|---|
| 90 | |
|---|
| 91 | 6 - There's no 6 ! |
|---|

| 95 | Troubleshooting : |
|---|
| 96 | ----------------- |

|---|
| 99 | |
|---|
| 100 | 2 - Restart CUPS. |
|---|
| 101 | |
|---|
| 102 | 3 - Set "debug: yes" in the [global] section of tea4cups.conf |
|---|
| 103 | |
|---|
| 104 | 4 - Print something on a print queue managed |
|---|
| 105 | by Tea4CUPS. |
|---|
| 106 | |
|---|
| 107 | 5 - Look at CUPS' error_log file for diagnostic and error messages. |
