Comment 13 for bug 428588

Alex, for Duplex printing you have to choose the "A4Duplex" page size instead of "A4" (or "LetterDuplex" instead of "Letter"). If your application's printing dialog allows changing the page size, change it appropriately and you should be able to print. If not, check whether you can choose the page size at other places, like in "File"/"Page Setup" (choose your printer in the first drop-down and then the "Duplex" page size in the second drop-down) or "Format"/"Page". If the "Duplex" page sizes are not accessible you are out of luck with that application (the application has a bug then, please report it).

Everyone, please try the HPIJS drivers on Karmic. For that open system-config-printer ("System"/"Administration"/"Printing"), right-click your printer's icon and choose "Properties". In the upcoming dialog stay on the first page ("Settings"), click the "Change" button in the "Make and Model" line and in the upcoming wizard keep make and model but choose in the driver field (second step, on the right) the driver with "hpijs". With this driver the options will look different, especially you will have every page size only once. Please tell how well printing works for you with this driver.
