Brother MFC J6920DW stopped printing dublex #6048

DrMartinus commented 1 year ago

Hi, I run Manjaro on my PC and have for several years A Brother MFC-J6920DW connected to it. After a system update about one month ago, the printer stopped printing duplex. I have the printer set up in CUPS as different printers each with different settings (like A3 foto, A4 duplex, A5...), so I can choose just one of those printers, and it would print - until that upgrade. I can continue to print one-sided. Only when I start a duplex job, the printer pulls in a sheet and then begins to wait for approximately 1 minute, before it spits out the empty page. CUPS treats the job as printed. It can be a hundred page document or a 2 page document, it's all the same. I have tried different places for help, like the Manjaro forums, but no luck. I am quite sure that his has to do with some settings within CUPS, but I don't know enough to try to fix it myself. The driver is provided by Brother and has worked flawlessly until... There was no driver update. Since then I have noticed, how often I need this functionality. In view of increasing scarcity of resources, environmental issues etc., it's a very valuable thing, and I need it back. Edit: I just see that this landed in Apple/Cups, where it shouldn't have landed. Sorry. It seems I can not move it to a different place. This is a Linux issue...

Hello DrMartinus,

Your Manjaro CUPS is not supported on apple/cups. You want

https://github.com/OpenPrinting/cups/issues

You are using the Brother printing drivers?

You have an IPP printer. A technique to test duplex printing is at

Cheers,

The "driver" from Brother is made for CUPS Version 1.4. Later Versions may or may not work. The specs say it can do AirPrint, which is not too bad, as that means it possibly works without a brother driver.

Thanks for the suggestions and ideas. Since I put this in the wrong section, I posted the issue again at https://github.com/OpenPrinting/cups/issues/429. I mark this now as closed and resolved, even though it isn't, but it's of no consequence for the apple/CUPS.
