This is a SNIP of a rather LONG FIX:
"Just purchased this thing and am running it a machine to print checks with (Win95, p1-200, 48 Mb ram). The Oki dot matrix printers don't give you drivers, they tell you to use the drivers from Win95 disk. Sure... (just lazy if you ask me :-) OK using the Oki Microline 184 IBM Turbo driver the thing works fine, EXCEPT that it *always* prints in NLQ mode no matter what the settings in the control panel, it just switches to NLQ before each print job. So... we switch to a "generic text" driver and it works fine that way EXCEPT that it no longer recognises the custom paper length (8.5" wide X 7" long) Now here's the wierd part... IF I switch back to the win95 driver, re-accept the custom paper size, print a test page (in NLQ of course), switch back to the generic driver, re-accept the the custom paper size, switch the printer to normal (non NLQ), and print it works fine with the custom paper size and non-NLQ mode until the next time it needs to print. The printer remains ON 24/7, so its not reseting itself. It just seems that with the Win95 driver there is no way to set it to print in anything but NLQ AND the generic driver refuses to keep the custom paper sizes in memory. Anyone seen this before? Never came accross this myself. I may just end up sending this thing back and getting an Epson or someting else."
AND THERE IS THIS:
"This is like going back to the dark ages....most of those old impact printers had dip switches to set things like default print quality. Additionally, Oki's usually came in two 'flavors'--plain Oki and IBM Oki. It's important that you install the correct driver between the two options..."
