We have a lab room of windows computers but the teacher has a iMac. The students using a windows computer have no issues printing to the HP Color LaserJet 5550. The windows computers use a printer server (Windows 2008 R2) where the iMac is printing directly to the IP Address of the printer.
The issue the iMac is having is the slowness of printing. If we print a color document from the iMac it takes about 1 to 2 mins for one copy. If I print 3 copies it take 5 to 6 mins. If i print from the windows computers the same document 3 copies it takes about 45 secs. It seems that the iMac is printing one copy at a time and maybe uploading (if this makes sense) the image to the printer then the printer is printing it.
Thanks for the help,
