Airprint print PDF about docker-cups-airprint HOT 13 CLOSED

A miracle happened, I accidentally changed another driver today, and the problem was solved.This issue can be closed.

My printer is hp laserjet 1320. I have tested its drivers one by one, and they all have the same problem. The driver I often use recently is HP LaserJet 1320 series Postscript (recommended) (en). Yesterday, I found out that your software was updated, so I updated it and chose another driver (HP LaserJet 1320 Series hpijs pcl3, 3.20.3), so it worked.

I'm honestly not sure if I can be of help. You can check the logs of the docker container and see if there are some errors. You can also try printing from other devices (windows/macOS) to see if they have the same issue. If so, you may want to try a different printer driver.

Thank you for your reply. I have no problems printing on windows and macos. Your program is very good. Only ios has trouble printing PDF. At present, I can use another AirPrint program, but the cups version of that program is relatively low. Still want to use your program. Please tell me how to view the log, my view log is blank.

And I tested all the drivers, it’s not a driver problem.

you should be able to follow the logs with docker logs -f <name-of-your-container> and then try to print.

After this, all the signal lights of my printer are all on, and it must be restarted to return to normal.

Looks like you have to manually adjust/add cups-filters. I haven't done that before to be honest, so I can't help you with that.

After searching around a bit, I found this: https://eloquence.marxmeier.com/sdb/html/1123683643.html But I'm not sure if that will lead to a solution.

Alternatively, looking into the "popper" topic, this might give a hint: OpenPrinting/cups-filters#169 (comment)

Thank you for your help! I read the content in the link, and to be honest, it is very difficult for me to modify your docker. I use QNAP NAS, and use your docker directly through the GUI. I tried to adjust it using the terminal, but encountered many errors. I'm just curious why another docker named “firilith” can print PDF files, but yours can't. firilith's docker doesn't seem to have a filter either, but it takes a long time to print PDF files.

The same pdf file, printed with ios and printed with pc, have different transmission sizes.

That's great to hear @master-ang, glad it works now!

Can you elaborate for the after world which driver you changed? Or was it unrelated to the cups?

Thank you for sharing your problem and solution. Closing this now as it is solved.
