We are getting some reports that the latest version of the Lexmark Universal printer driver is changing the port number of the printer port on Print Distributor virtual printers.
The printer port is used by the virtual printer to redirect the print documents into Print Distributor so if the port is changed then Print Distributor will not receive the document and the print queue will show an error.
You can resolve this issue with these steps:
If you change any of the other printer properties then the driver will change the port number so you will need to go through this procedure again.
We have released a small update today which checks for any mis-configured ports on startup and logs an error.
We have also contacted Lexmark to try and find a permanent fix to this problem.
Note: Switching to the Named Pipe based virtual printer also resolves this problem. This virtual printer was labelled as the Legacy printer however we have had a change of heart on that and in the latest release it is back as a fully supported virtual printer.
