Printer cannot print multiple copies

Hello, guys. I have some problem please help me.

I use Endeavouros in my office. Everything ran well, until about a week ago when I tried to print multiple copies of my document. It only prints one. I tried other printers, same results, so I think it is not the driver issues.

FYI, I tried to edit .ppd files in /etc/cups/ppd. I changed

cupsManualCopies = True

to true (lowercase), didn’t work.

Any suggestion is appreciated. Thanks in advance!

Downgrade the following file, there is regression in the latest version

extra/libcupsfilters 2.2.1-2 (563.8 KiB 1.5 MiB) (Installed: 2.1.1-4)

great, It works. I have downgraded 2 versions prior and problem solved… at least for now. Thank you very much. How did you know there was a regression btw?

It was reported here and I relayed what I did to fix it.
