cups-driverd - cups driver daemon
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
Ilimit 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
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
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
"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,
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 prefixes are recognized:
