Corrupt print jobs when sending via Novell

When sending print jobs via a Novell print server, print jobs arrive corrupt at the printer.

Set up as follows:

iPrint Client -> NetWare 6.5 SP7 + NDPS Gateway (NDPSGW) + Printer Agent -> Via LPD -> Pharos Uniprint running on Microsoft Windows 2003 -> Physical Printer

The corruption appears to be a as a result of the LPR/LPD communication between Novell LPR and the Pharos LPD service, which is not seen with the Native Windows LPD.

As part of the troubleshooting process, adding THROTTLE=2 parameter to the agent (per Novell TID 3233501) fixes this issue but slows things down causing a backlog of print jobs. This is to be expected as the THROTTLE switch is designed to slow down the print job in order to allow the receiving LPD service, in this case Pharos Uniprint, to keep up. Printer pooling can be used to set up multiple LPD paths to the server to compensate for the throttle delay.
