edit cups config file

pablo27 · 09-11-2020, 08:27 PM

I am running MX linux 19.2, with a Epson WF840 printer. The problem I am running into is that in order to use duplex printing I must add it to the cups config file. And I don't have any idea what the correct syntax is. Here is the default config file:

# Show troubleshooting information in error_log.

I don't see where it is set up to do one-sided printing so don't know how or where to add the duplex option. Thank you in advance for your time and advice

You can use the CUPS web interface (via a browser) or the CUPS 'lpoptions' command to set printer options. If invoked as user, it will create ~/.cups/lpoptions with the preferred settings AFAIR. Other (system-wide) options may be set in the ppd file (located in /etc/cups/ppd/ directory) for the printer concerned. The following page will give you an idea about using the 'lpoptions' command...

https://www.thegeekstuff.com/2015/01/lpadmin-examples/

The current options for a given printer can be got using something like

Code:

lpoptions -p <printer_name> -l

For example

Code:

lpoptions -p HP_HP_LaserJet_Pro_M428f-M429f -l

Referring to the above, I could set A5 paper size using...

Code:

lpoptions -p HP_HP_LaserJet_Pro_M428f-M429f  -o A5

Reference

Code:

man lpoptions
