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 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 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:
drivername list
Lists the supported PPD files to stdout.
drivername cat ppdname
Writes the named PPD file to
stdout. 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,
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. 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]
