While I've been scanning successfully using XSane and Simple Scan, when I attempted to use XSane (version 0.998 on 64 bit Ubuntu 12.04 LTS) in Copy mode it told me no printer was defined. I opened the "copy" tab in "xsane setup" and clicked the "Add printer" button, but no dialog appeared.
Apparently, this does not bring up a list of OS printers, as I would have expected, but adds the define an existing CUPS printer with various entries on the dialog box (e.g. "Name," "Command," and so forth). Since it looks like Ubuntu is using CUPS as an intermediary for all printers, I tried using the names I got from the "Printers" dialog from the icon in the upper right corner of the desktop, but none of them seem to be recognized.
Is there a way to use my HP Inkjet printer (which works just fine with Ubuntu) to print out scans directly from XSane? I can, of course, save the scan as a pdf or something and then print it, but it seems like I must be missing something somewhere. If so, how would I go about doing this?
