Handle requests for a printer's resources
|
You must be root to start spooler. |
spooler -d device [options]
Neutrino
- -C
- Calculate and print the device ID, and then exit.
- -c config
- The name of the configuration file that defines filters and properties
for a printer.
- -d device
- The output device (default: /dev/null).
- -F
- Disable file spooling and connect applications to filters using FIFOs.
- -f maxjobs
- Limit the number of simultaneous spool files to maxjobs.
The default is no limit.
- -g
- Make the printer a global network resource.
- -n name
- The name of the printer.
If this option isn't specified, spooler gets the name from
the PnP model or the configuration file.
The Print dialog for a Photon application uses this name in the list of
available printers.
- -P PnPstr
- The PnP string for a printer (default: query printer).
- -s spooldir
- The spool directory (default:
/var/spool/printers/printer-name).
- -v[v...]
- Verbose output; each addition v increases verbosity.
The spooler allows multiple users to share the resources of a
single printer.
If you have more than one printer, you can start an instance of
spooler for each one.
The spooler is usually started by an enumerator, such as enum-par
(see enum-devices),
as follows:
spooler -d /dev/par1
or you can start spooler (e.g. for a network printer) in
your /etc/rc.d/rc.local file — see
Controlling How Neutrino Starts
in the Neutrino User's Guide.
When you start spooler, it queries the printer to determine its
type.
If you provide a PnP string, spooler doesn't query the printer for
it:
spooler -d /dev/par1 -P PnPstring
You can use other options to force spooler to use a configuration
file and assign a name to the printer, but this isn't recommended:
spooler -c pcl -n My_PCL_Printer -d /dev/par1 &
You can find configuration files for commonly used printers in
/etc/printers.
These files specify the possible and default settings for the printers, as
well as filters for converting output to a form that the printers understand.
Photon applications use spooler for printing.
The filters that convert Photon draw-stream (.phs) output are
named phs-to-*.
For a graphical interface to spooler, see
prjobs.
