Re: Cups automatic duplex printing problems

Hi Michael / hi list,

Printers I tried yesterday were a somewhat older and veeeeery slooooow 
HP Laserjet CP5225dn and a more modern Xerox Altalink C8155. They're 
connected through plain old ethernet. The network is rather 
straightforward if not a bit old fashioned, with IPv4 192.168.something/24.

Debugging (i.e. trying what works and what doesn't) is rather tedious: 
remove printer; print simplex, 2 copies, duplex 2 copies; add printer 
manually; print simplex 2 copies then duplex 2 copies. The CP5225dn 
takes ages to fulfill its duties...

The first "I cannot print duplex" messages in my mailbox are from 
november 2022. The "I cannot print multiple copies" is from November 
2023 - not sure if it worked before, though.

I'll try the "logging" option next time when I'm in the office.

Best regards,

Valentijn
