Printing with spooler
 2005, QNX Software Systems
If you ask a Photon application for a print preview, it sends the output
to the preview utility. If you want to view or manage the print
queue, start prjobs from the command line, or select
Utilities→Print Manager from the Launch menu. For more
information, see the Utilities Reference.
Remote printing over Qnet
To print across Qnet, print to
/net/nodename/dev/printers/printer name/spool. The
spooler program for the printer must be running on nodename.
Remote printing over TCP/IP
If you want to set up spooler to print on a remote printer, you can
pipe the print job to lpr. This takes advantage of the fact that the
filter sends the print job to the printer; you just name the remote
printer in the filter command line of the configuration file used by
spooler.
To try it, first get your remote printer working using lpr (see
“Remote printing to a TCP/IP-enabled printer using lpr”), then do
the following:
1
Copy the configuration file from the printer you want to use (in
this case, a PostScript printer):
cp /etc/printers/ps.cfg /etc/printers/test.cfg
2
Find the filter command lines in test.cfg; they look like this:
Filter
Filter
=
=
phs:$d:phs-to-ps
raw:$d:cat
These filter command lines are in the form:
source:destination:filter
The phs filter command line tells the filter to process .phs
files by sending them through a filter called phs-to-ps before
sending them on to the destination passed by spooler. The
raw filter command is for utilities that already produce the
correct output for the printer.
