Printer problems

[Gnigma]

This new printer is giving me fits. It's a Pantum P2502W. Works fine when I boot into Windows 10. I've got Ubuntu 18.04.3. I've gone through the install, loaded the driver, and all I get is "Job stopped." Nothing in the troubleshooting log. Oh, I'm on an Asus 52 laptop. Ideas?

[brian_p]

Give the output of
driverless when the device is on the network.

[Gnigma]

That gives me nothing. I'm down to just trying to get the POS to work off the USB cable, and I still get nothing.

[brian_p]

On 18.04 it has to give you something when the Pantum is on the network. What do you get for
avahi-browse -rt _ipp._tcp and
avahi-browse -rt _uscan._tcp

[brian_p]

Forget about the second command.

[Gnigma]

I put both in and still get nothing.

[brian_p]

I put both in and still get nothing.

According to https://support.apple.com/en-gb/HT201311 the Pantum P2502W is an AirPrint device, but your data shows no sign that it is. Either AirPrint is not activated or the Pantum is not on the network. Not being activated is a possibility, as indicated by https://global.pantum.com/global/airprint-support/. A firmware upgrade would give you the capability of not using Pantum drivers.

Anyway, upgrading is up to you. For now, we'll take a look at your present situation.

You should have a PPD for the printer in /etc/cups/ppd. Execute this command
sudo cupsfilter -p /etc/cups/ppd/<the_PPD_name> -m printer/foo -e --list-filters /etc/nsswitch.conf and post the output. Do not type the angle brackets.

Now do
sudo cupsfilter -p /etc/cups/ppd/<the_PPD_name> -m printer/foo -e /etc/nsswitch.conf > out.dat 2>log

Look at log and say whether any of the filters fail.

[Gnigma]

OK, output from the first line is:

cupsfilter: File "/usr/lib/cups/filter/pt2500Filter" permissions OK (040755/uid=0/gid=o)
texttopdf
pdftopdf
gstoraster
pt2500Filter

The second line had no results.

[brian_p]

OK, output from the first line is:

cupsfilter: File "/usr/lib/cups/filter/pt2500Filter" permissions OK (040755/uid=0/gid=o)
texttopdf
pdftopdf
gstoraster
pt2500Filter

That is what I would expect.



The second line had no results.

There isn't any output to the screen; the output goes into the file log. You can see it with
less log

We want to know if all the filters above run successfully. Also give the output of
ls -l out.dat

[Gnigma]

The site keeps telling me I don't have permission to post replies now.

[Gnigma]

ls -l out.dat gives me:

-rw-rw-r-- 1 jim jim 0 Nov 28 8:43 out.dat

[Gnigma]

I think the error log file is too big.

[Gnigma]

Yeah. Converted to text, it's 1198 pages!

[brian_p]

Yeah. Converted to text, it's 1198 pages!

I have no idea what you are on about. However, out.dat has zero size. That is not good. How about
ls -l log

[Gnigma]

-rw-rw-r-- 1 jim jim 4532 Nov 28 08:43 log

[brian_p]

-rw-rw-r-- 1 jim jim 4532 Nov 28 08:43 log

A small file. Compress it with
gzip log and post log.gz as an attachment.

[Gnigma]

Latest one:

[brian_p]

Your error_log.2 shows
GPL Ghostscript 9.26: Unrecoverable error, exit code 1 This indicates a problem with your Ghostscript installation. You could try updating the system or reinstalling Ghostscript.

[Gnigma]

I've uninstalled and reinstalled Ghostscript. It still stops the job before printing.

[brian_p]

All I can think of is directly testing the gstoraster filter, which uses Ghostscript:


cupsfilter -m application/vnd.cups-raster /etc/nsswitch.conf out.ras 2>LOGFILE

Have a look at LOGFILE yourself and also send it here as an attachment.

[Gnigma]

LOGFILE just said: cupsfilter: Only one filename can be specified.

The zip file from earlier is still on the attachment window, and it won't let me remove it, nor will it let me add another attachment. Here is the troubleshoot-logs.text file:

[brian_p]

LOGFILE just said: cupsfilter: Only one filename can be specified.

An attempt at correcting my typo would have been appreciated. :)


cupsfilter -m application/vnd.cups-raster /etc/nsswitch.conf > out.ras 2>LOGFILE

[brian_p]

The zip file from earlier is still on the attachment window, and it won't let me remove it, nor will it let me add another attachment.

Just send it inline as you did with the troubleshoot-logs file. It is not very large.

Still can't erase the zip file, but here's LOGFILE output.

Never mind about the zip file. This output is what was needed. It shows


INFO: gstoraster (PID 16919) exited with no errors.

In other words - Ghostscript ran correctly without any problem.

Now do again exactly what you have done here but post what you get for this command:


cupsfilter -p /etc/cups/ppd/P2500W.ppd -m application/vnd.cups-raster > /etc/nsswitch.conf out.ras 2>NEWLOGFILE

amd post NEWLOGFILE.

OK, update. Obviously, the line "no ppd file specified" was the clue. I was able to locate an older install package, which said to first run the install without the usb cable connected to the printer. (?!!) I deleted all the previous files related to the printer before I did that, and it failed, then I connected the cable and ran the install package again. It worked. So, the printer is up and running, but I still don't understand why the PPD didn't load from the newer package. Maybe it's a glitch in the newer install program? Anyway, I really appreciate your time and help, Brian. I was beginning to think I was going to have to print everything through WINE!

A splendid outcome! Well-done for sticking with it and being patient. Sometimes, all that is required is time to reflect.

For future readers I'd like to point out a mistake of mine. The cupsfilter commands I gave should have been prefaced by sudo.. That is,
sudo cupsfilter.......

Oh, yeah. I was doing that from the first, when it said "you don't have permission." ;)
