This method is the method used by # default in PyKota since its beginning. # # - external : delegates the job's size computation to any # external command of your choice. A stupid and # completely unreliable example, but which # shows what this command may be is : # # accounter: external(/bin/grep -c showpage) # # Another one, which should work with all DSC # compliant Postscript files : # # accounter: external(/bin/grep -c "%%Page:") # # - stupid : counts the occurences of the 'showpage' postscript # statement in the document to be printed. # THIS IS NOT RELIABLE. This is just to serve as # an example on how to implement your own accounting # method. # # This value can be set either globally or on a per printer basis # If both are defined, the printer option has priority. # if not set it defaults to 'querying'. # # A script which seems to be accurate, copy it from the # untested/postscript directory to another place. # accounter: external(/usr/local/bin/pagecount.sh) # WARNING : it may not work when multiple copies are asked. # this breaks ghostscript, I don't know why yet. # # default value accounter: querying # Print Quota administrator # These values can be set either globally or per printer or both. # If both are defined, the printer option has priority. # If these values are not set, the default admin root # and the default adminmail root@localhost are used. admin: John Doe adminmail: root@localhost # # Who should we send an email to in case a quota is reached ? # possible values are : DevNull, User, Admin, Both, External(some command) # The Both value means that the User and the Admin will receive # an email message. # The DevNull value means no email message will be sent. # This value can be set either globally or per printer or both. # If both are defined, the printer option has priority. # If the value is not set, then the default BOTH applies. # # Format of the external syntax : # # mailto: external(/usr/bin/mycommand >/dev/null) # # You can use : # # '%(action)s' will contain either WARN or DENY # '%(username)s' will contain the user's name # '%(printername)s' will contain the printer's name # '%(email)s' will contain the user's email address # '%(message)s' will contain the message if you want # to use it. # # On your command line, to pass arguments to your command. # Example : # # mailto: external(/usr/bin/callpager %(username)s "Quota problem on %(printername)s" >/dev/null) # # To automatically send a WinPopup message (this may only work with a PDC, # here the same machine does Samba as PDC + CUPS) : # # mailto: external(echo "%(message)s" | /usr/bin/iconv --to-code utf-8 --from-code iso-8859-15 | /usr/bin/smbclient -M "%(username)s" 2>&1 >/dev/null) # # NB : I use ISO-8859-15, but Windows expects UTF-8, so we pipe the message # into iconv before sending it to the Windows user. # # or more simply : # # mailto: external(/usr/bin/mailandpopup.sh %(username)s %(printername)s "%(email)s" "%(message)s" 2>&1 >/dev/null) # # NB : The mailandpopup.sh shell script is now included in PyKota # # NB : in ANY case, don't forget to redirect your command's standard output # somewhere (e.g. >/dev/null) so that there's no perturbation to the # underlying layer (filter or backend) # mailto: both # # Grace delay in days # This value can be set either globally or per printer or both. # If both are defined, the printer option has priority. # If the value is not set then the default seven (7) days applies. gracedelay: 7 # # Poor man's threshold # If account balance reaches below this amount, # a warning message is sent by email # # If unset, default poor man's threshold is 1.0. # This option can only appear in the global section poorman: 2.0 # Poor man's warning message # The warning message that is sent if the "poorman" value is reached # Again this must appear in the global section poorwarn: Your Print Quota account balance is low.
