We setup a Ubuntu server for our print server. We have a combination of Konica and HP model printers. For the HP models that are capable of it doublesided priting works fine. I cannot get it to work on any Konica. The option in the properties only shows 1 sided. In the CUPS URL it shows 2 sided but when you set that as default it still reverts back to 1 sided. Is there any way to do double sided printing with a Konica on Ubuntu?
