ethernet printer setup

QNX USERS QNX6 - OS
1

Hello,

Is anybody using a networked (tcp/ip addressable) HP LaserJet with QNX?

I’m trying to connect my QNX workstation to a networked printer. It’s working, but not properly (so far).

The printer is a HP LaserJet Professional P1606dn. It’s named tcpip_printer and I’ve added entries to /etc/hosts and /etc/printcap.

Command “lpr -Ptcpip_printer printer_test.txt” queues up the test file and, after several minutes, prints it out. The test file is a single line of plain text, i.e. “this is a test”. Two pages are printed for this:

page 1

this is a test
@84 cfA000qnx2

page 2

Hqnx2
Proot
Jprinter_test.txt
Cqnx2
Lroot
fdfA000qnx2
UdfA000qnx2
Nprinter_test.txt

end of printout

File /etc/printcap is:

/etc/hosts maps the printer ( “tcpip_printer” ) to its IP address.

tcpip_printer:
:rm=tcpip_printer:rp=/pcl:sd=/var/spool/output/lpd/tcpip_printer:

I’ve never before configured a printer for QNX, much less a directly addressable ethernet printer.

Any tips or suggestestions would be aprpeciated.

Thank you.

David

I haven’t done this with an HP, but I have with a Kyocera. From your message it looks like the data is getting to the printer ok, which is usually the hardest part. I suspect that you are not using the right filter on the text. Most likely you want the PCL output filter.

I’m not where I can look things up so this is a little sketchy. If you can’t figure it out, reply and I’ll look up the details.

I strongly suspect that my /etc/printcap entry is incorrect, most likely the “rp=/pcl” specification.

If you could post the Kyocera lines from /etc/printcap, that would be very helpful.

Thank you.

Thank you for your printcap file. I’ve modified mine a bit, but printing is still not working as desired.

Being new to QNX and printer setup, I suspect I’m missing something simple. Unfortunately I don’t know what that might be.

Using a “lpr -Ptcpip_printer …” command creates files in /usr/spool/output/lpd/tcpip_printer. After a few minutes the files might be printed, though usually the files just sit in the spool directory.

I’ve documented below the contents of my /etc/printcap file and various results from running “lprc”. Being new to QNX printing I don’t know if these outputs are correct or not.

Suggestions are requested!

Regards,

David

/etc/printcap is

tcpip_printer: \
	:direct: \
	:rp=/pcl: \
	:sd=/usr/spool/output/lpd/tcpip_printer: \
	:ifhp=model=laserjet4: \
	:filter=/usr/local/libexec/ifhp: \
	:sh:

I’m using command “lpr -Ptcpip_printer printer_test.txt” to test printing.

“lprc status” shows
tcpip_printer:
queuing is disabled
printing is enabled
2 entries in spool area
sending to tcpip_printer

but the printer isn’t printint anything.

Using “lprc enable all” changes the output of “lprc status” but printing isn’t happening.

As an experiment, I tried “lprc restart all”, which displayed:

tcpip_printer:
		no daemon to abort
tcpip_printer:
		printing enabled
		daemon started

The “no daemon to abort” line is suspicious, so I ran “lprc restart all” again. It displayed the same output as before:n

tcpip_printer:
		no daemon to abort
tcpip_printer:
		printing enabled
		daemon started

Directory /usr/spool/output/lpd/tcpip_printer/ has the following files:

Still not working as desired, sigh. Being new to QNX and printer setup, I suspect I’m missing something simple. Unfortunately I don’t know what that might be.

Below is what I’m seeing.

I don’t see anything obviously wrong. I’ll mention one thing I’ve had to deal with.

Before printing I have to start the print daemon lpd:

lpd

If I power down at this point, I can no longer start lpd. The solution is to first run chkfsys and fix the file system.
There is always a file /usr/spool/output/lpd.lock which left busy.
