My parents own a new iMAC and recently bought an HP Photosmart 7760 photo printer. They were trying to print a wedding shower invitation which measures 8.5 x 5.5 (printable area is 4 x 6). However, each time they tried printing, it wouldn't work - the printer stops and goes into a que status. When they tried printing on "regular" 8.5 x 11 it would work fine. They called the HP help desk and were told that the OSX platform wouldn't support "custom" paper sizes, but that the OS9 would. Is there any way to work around this? Any suggestions? My parents are about to go postal on the entire computer and printer - they are ready to give it all up out of frustration. Any help is appreciated!
