    75   Problem may arise however in batches on successive print jobs  
    76   by different users when there's no sleep time between two jobs : 
    77   the used pages may be attributed to incorrect user. This 
    78   depends on the printer speed and time between jobs. 
    79    
    80   Other querying methods which won't suffer from this problem, 
    81   but probably from other ones ;-) will be implemented in the  
    82   future. 
     75  Problem may theorically arise in batches of successive print jobs by  
     76  different users when there's no sleep time between two jobs : the  
     77  used pages may theorically be attributed to an incorrect user in the  
     78  case that the printer is asked for its page counter at the beginning  
     79  of a new job and before the end of the previous job. This depends on  
     80  the printer speed and time between jobs, but so far I've not seen  
     81  any problem with moderately used printers. This also depends on CUPS  
     82  internal behavior : if CUPS doesn't begin to send a job to a printer  
     83  before the previous one is completely printed, then there's no  
     84  problem.

     86  Other querying methods which won't suffer from this possible  
     87  problem, but probably from other ones ;-) will be implemented in the  
     88  future.

    113119  Server. 
    114120   
    115   Of course the CUPS Server and the Quota Storage Server can be the   
    116   very same machine.  
    117    
    118121  This list of prerequisite software may change in the future, when 
    119122  PyKota will support more functionnalities you will be given  
    120123  alternatives. 
     124   
     125  Of course the CUPS Server and the Quota Storage Server can be the  
     126  very same machine if you've got a tiny network, or you can have  
     127  multiple CUPS Servers all storing their quotas on the same Quota  
     128  Storage Server if you've got a bigger network.

    122130Then :    
    … …  
    158166to enable quota on every printer. 
    159167           
     168WARNING : In the case you've got a non-postscript printer, chances 
     169          are that the *cupsFilter is already filled-in and points 
     170          to cupsomatic or such a print filter. In this case please 
     171          check if you can switch your printer to PostScript mode 
     172          or if there's a way to make it accept PostScript jobs. 
     173          If yes then ensure that your workstations uses a PostScript 
     174          printer driver, and replace the *cupsFilter line with the 
     175          one pointing to the pykota filter. This should work, but 
     176          is currently untested. 
     177          If your printer really needs the original *cupsFilter line 
     178          then you may not be able to use PyKota easily for now.
