Printer is not connected to a port

[MarkB2]

I have an application that has been running fine for a long time. We just installed Windows 2003 server and updated the workstations to service pack 2 of windoes XP. Prior to last weekend the network was peer 2 peer and on windows XP SP1. FM is installed on one workstation and the files are also stored on the same WS. A number of reports that used to print fine to a HP Color LaserJet 5 are now displaying a message as follows:

---

Printing can not continue because this printer is not connected to a port. Use the Control Panel to set up a port.

---

The printer in question was not changed. It has always been connected locally to the WS using LPT3 parallel connection. It looks like the driver was not updated as part of the install. The reports are set to print to the default printer. If I change the default printer to a USB connected DeskJet the reports work fine.

Any help would be appreciated.

PS: I installed a version of the application from a backup which was version FM 3 or 4.1 and it also had the same problem.
