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 argu-
ment 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 section.
Driver programs provide an interface to dynamically-generated PPD files. The following
arguments are currently defined:
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 format:
"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, typi-
cally "en". Make is the Manufacturer name from the PPD file. Make and model is the Nick-
Name 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.
DRIVER ERROR MESSAGES
Error messages can be relayed back to cupsd by writing them to stderr. The following pre-
fixes are recognized:
cupsd(8), cupsd.conf(5), cupstestppd(1),
