Duplex printing with cups
We have a bunch of Macs all running 10.4.9 (Client) which are unable to print double-sided documents to our printer which is hosted by a redhat enterprise server (v4.4) box, cups version 1.2. The annoying thing is everybody else (windows, linux) can. The printers are set up as A4 paper size, the Macs see that and we see the duplex option in the print dialog box but the printouts come out single-sided with a blank sheet at the end. Another aspect is that when we add a printer using System prefs>Print & Fax etc the cups printer description is displayed as the printer name in the set up dialog on the Mac. Has anybody come across this before and, more importantly, does anybody know how to solve this problem?
Cheers,
Matt
