[opensuse-factory] POS thermal printer test page prints, but can't print receipt.
I have successfully set up a thermal printer in printing a test page using the drivers provided by the manufacturer here: http://www.sprt-printer.com/Item/list.asp?id=1724 But when I attempt to print a receipt from the odoo POS system, nothing gets printed on the 80 mm wide thermal paper, although the thermal printer cuts off exactly 20 mm of the unprinted paper. The Print Queue states "No pages found!" I have tried saving the file as a .pdf and .ps to be printed separatedly outside of the browser, but the problem still remains. How do I diagnose the problem to get receipts properly printed? Any ideas?

Do those files contains the correct stuff? -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" at Telcontar)

Could you clarify your meaning? I do not understand which files you are referring to.
You said "I have tried saving the file as a .pdf and .ps ", I'm sure those are the files Carlos was asking about. -- Per Jessen, Zürich (23.3°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Yes. Those files do contain the information to be printed. He could also have been asking about the ppd driver files provided by the manufacturer, hence the ambiguity of the question.

Well, no, because my question was written exactly next to the paragraph in which you mentioned the pdf and ps files :-) Unless your mail client hides the quoted text. Anyway, the ps and pdf files contain the correct stuff that you want to print, and yet if you print those files using command line tools like "lpr file.ps" they don't print? Well, the next thing to do now is to look at the cups logs. They are in "/var/log/cups/". You probably want to increase the verbosity; that is done in "/etc/cups/cupsd.conf". Change the line: LogLevel Warn with LogLevel debug or debug2. Restart the cups daemon and try again. -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" at Telcontar)

No. They won't print. It spits out 2 cm of blank paper.

I see a debugging message called "No authentication data provided" Perhaps that could be it? I have pasted a snippet of the relevant log section at http:// paste.opensuse.org/1636302 Thanks for the help! :-)

Doesn't seem likely...

Welcome... Unfortunately, I can't find what is wrong by looking there. There is a section where it appears to send the print job: Look at line 129, it seems to be the start of a print job. On line 142 it is applying the filters. ps to pdf, pdf to pdf, then pdf to raster, then raster to printer. On line 147 it says "job-sheets=none,none". Line 154 says that the job is cached as "/var/spool/cups/d00010-001" - you can check if the file is still there, it probably is a pdf inside (run "file /var/spool/cups/d00010-001" to find out). Line 186 seems to start each filter job. I do not know what is the result of each filter. Did they succeed? Can we look at temporary files? At line 190 it starts the backend to send it via USB to the printer itself, I suppose. Maybe at line 193 it says it finished sending the print job. Line 287 is a ghostscript command used. What for...? And here I get lost, because on line 451 I see the same thing, so I don't know if you repeated the print request or what happened. We need to know for sure that the log is for a single print job, and where does the log start. I'm not trained in reading CUPS logs... I see a bunch of cupsdWriteClient commands. I see a "data_remaining=994" with the number diminishing each time, but barely so. Line 590 seems to be sending print job and displaying the percent. -- Cheers / Saludos, Carlos E. R.

It seems the previous print job, although it "printed" a blank page, was still in the queue, oddly enough. I will rerun the test cleanly without any print jobs and submit a new log file.

PID 3286 (/usr/lib/cups/filter/rastertoprinter) exited with no errors. PID 3287 (/usr/lib/cups/backend/usb) exited with no errors. ------------------------------------------------------------------------ Accordingly there are no errors while processing the job by the printing system (i.e. CUPS and printing filters/drivers). I assume /usr/lib/cups/filter/rastertoprinter is your special manufacturer's printer driver. It seems the final outcome of the print job processing (in particular what comes out of the printer driver /usr/lib/cups/filter/rastertoprinter) that is sent by the CUPS backend to the printer device does not make the printer device actually print something. For some details about print job processing have a look at https://en.opensuse.org/SDB:CUPS_in_a_Nutshell I recommend to ask your printer driver's manufacturer how to install and use his printer driver software.

Thanks Johannes. I managed to get the printer's driver software engineer on email, and he sent me some SDKs. I will nudge him into the right direction with this information!

Just a quick update. The company seems interested in the process of working with openSUSE to get their driver submitted, and GPL-compliant. I have encouraged them to read the provided documents and to join the mailing list to get further help.

Many thanks for your efforts! It helped a lot. Because you are in contact with the printer's driver software engineer could you also point him to https://en.opensuse.org/openSUSE:How_to_contribute_to_the_Printing_project This SDB article and those that are linked therein describe how the printer's driver software engineer could get his driver into the OBS "Printing" project (provided his driver got enhanced into true free software). FYI: It seems currently openSUSE SDB articles are unaccessible because of error 503: "Sorry, the page you are looking for is currently down for maintenance" - but some time later it should (hopefully) work again.
