I've given it as much encouragement as a I can, short of physically cheering on the printer as I try to connect to it.
I get to the add printer dialog box, it finds the printer, I try to add it, it hangs on the "acquiring printer information" progress window for a few minutes. Sometimes this is indefinite, sometimes it does seem to "acquire the information." But even in that case, when the printer shows up on the list of possible printers I might add to the accounting program, it says it can't communicate with the printer, and I can't add a printer I can't communicate with.
Any info you have would be helpful though, thanks. Hopefully I will get it sorted out with Canon's help soon.
