I am attempting to install a Okidata ML 390 for use in the XPMODE of the virtual PC running under Windows 7. The symptom is as follows.
Install appears fine using the selected driver in the XP side attached directly to the parallel port of a Lenovo ThinkCentre. Printing a test page fails to print
Printing from notepad fails to print even though the document screen briefly shows the print job then ends as if it printed.
Installing the printer on the Windows 7 side (using the ML490 driver since 390 is not there) prints a pretty test page.
None of the troubleshooting steps changed the symptom i.e. no error message - just no response from the printer.
