       cups-driverd - cups driver daemon


       cups-driverd cat ppd-name
       cups-driverd list request_id limit options


       cups-driverd  shows  or lists PPD files. It is run in response to CUPS-
       Add-Modify-Printer  or  CUPS-Get-Devices  requests.   The  first   form
       ("cups-driverd  cat ppd-name") writes the named PPD file to stdout. The
       output format is an uncompressed PPD file.

       The second form lists the  available  manufacturers  or  PPD  files  to
       stdout  as  indicated  by the options argument. The output format is an
       IPP response message. The request_id argument is the  request  ID  from
       the  original IPP request, typically 1. The limit argument is the limit
       value from the original IPP request - 0 means no  limit.  Finally,  the
       options  argument  is a space-delimited list of attributes ("name=value
       name=value ...") that were passed in with the request. Currently  cups-
       driverd  looks for the ppd-make and requested-attributes attributes and
       tailors the output accordingly.


       Drivers  can  be  static  PPD  files  under  the  /usr/share/cups/model
       directory  or programs under the /usr/lib/cups/driver directory. Static
       PPD files must conform to  the  Adobe  PPD  File  Format  Specification
       version  4.3  and  may  be compressed using the gzip(1) program. Driver
       programs must implement the command-line interface shown  in  the  next

       Driver  programs  provide  an  interface  to  dynamically-generated PPD
       files. The following arguments are currently defined:

       drivername list
            Lists the supported PPD files to stdout.

       drivername cat ppdname
            Writes the named PPD file to stdout.

   LISTING FILES (drivername list)
       When run with the single argument "list", the  program  must  list  the
       available  PPD  files  it  can  generate  to stdout using the following
           "drivername:ppdname" language "make" "make and model" "1284 device id"

       Drivername is the name of the driver program. Ppdname is the name  used
       to  select the given driver. Language is the locale associated with the
       default  language  of  the  PPD  file,  typically  "en".  Make  is  the
       Manufacturer  name  from  the  PPD file. Make and model is the NickName
       name from the PPD file. 1284 device id is the 1284DeviceId from the PPD
       file, if any.

   WRITING FILES (drivername cat ppdname)
       When  the  driver  program  is run with the "cat ppdname" arguments, it
       must write the named PPD file to stdout, uncompressed. If the named PPD
       file  does  not  exist, the driver program must not write any output to
       stdout and report the error to stderr instead.

       Error messages can be relayed back to cupsd by writing them to  stderr.
       The following prefixes are recognized:

       DEBUG: [drivername]
            Debugging messages

       ERROR: [drivername]
            Error messages

       INFO: [drivername]
            Informational messages
