A neighbor just installed an Okidata 4w on his son's computer.
The printer will only print from a Windows app, or a DOS app
run from inside the Windows DOS box. The son uses WordPerfect
5.1. When he tells it to print, there is disk activity but nothing
prints unless he then exits WP back to Windows.
The printer uses its own print manager program, not the Windows
print manager. Has anybody got a suggestion on how to make
it print without exiting the program? By the way, all the DOS
programs exhibit the same symptoms.
