Due to our configuration at the moment, in order to print certain documents we create a print file (xxx.prn) and send it to the printer from the command prompt; type xxx.prn>prn or any of the other commands to print from the prompt. This has been working fine until two days ago. Now nothing will print using this method. The printer is working correctly. I can print a test page, print from Word or Notepad, etc. When I try to print from the command prompt, the printer queue icon flashes briefly in the system tray and then disappears and nothing is output from the printer. The LPT1 port appears to be configured correctly and is enabled in the device manager. I know I can print these documents from Notepad or Wordpad but some of the headers and titles don't print correctly due to various programming so I have to be able to print from the prompt. Any suggestions what to look at next or where to check for configuration errors? I'm stumped on this one. Thanks for any assistance.
