I am having problems printing from my mac OSX 10.5 from archicad 12 to my canon irc3080 with a fiery J1.not all colours are coming out the same and some parts of the print are missing.If I save the file to a PDF it prints out ok
I would be very tempted to point the finger at archicad and demonstrate that the machine works fine from common applications and advise them to contact archicad for further support.
