We have some kind of unix (unknown) server that has for years sent print jobs to USB printers (different models: HP, Lexmark, Epson), each of which are attached to a Windows computer on the same network. The computers were upgraded to Windows 7 and since then, only one of 3 printers is working with Windows LPD. The computers were previously running Windows 2000 and 3rd party LPD server software.
Here is the setup on each computer:
- Each Windows 7 computer has all Windows Features turned on under Print and Document Services (including LPD, etc.).
- The ip addresses for each workstation are unchanged.
- In Devices and Printers, a separate queue has been added to handle LPD, with driver set as Generic Text Only and the share name set to the correct LPD queue name.
- The firewall is not blocking port 515 and in fact, print jobs seem to flush through the print queue, but nothing comes out on the printer.
How can I troubleshoot this and determine why it works on one computer but not another? Please note that I have little control on the server side, which we are trying to keep unchanged.
