CUPS DSS and PSF-Other tuning

CUPS DSS and PSF-Other DSS are driving CUPS printers. CUPS scheduler, cupsd, can be configured using the cupsd.conf file. It is normally located in the /etc/cups directory. Refer to the CUPS documentation if you think your printing environment needs changes to the default configuration.

Examples of directives understood by cupsd:

  • MaxClients

    The MaxClients directive specifies the maximum number of simultaneous clients that are allowed by the server. The default is 100 clients.

    Example: 

    MaxClients 1024

  • MaxJobs

    The MaxJobs directive specifies the maximum number of simultaneous jobs that are allowed. Set to 0 to allow an unlimited number of jobs. The default is 500 jobs.

    Example: 

    MaxJobs 0

  • LogLevel

    The LogLevel directive specifies the level of logging for the ErrorLog file. The following values are recognized (each level logs everything under the preceding levels):

    • none - Log nothing
    • emerg - Log emergency conditions that prevent the server from running
    • alert - Log alerts that must be handled immediately
    • crit - Log critical errors
