We're struggling to persuade Windows 7 to print to an OKI Microline 320 Elite printer connected to the network by an HP JetDirect. We've tried a whole raft of drivers:
OKI ML 320 Elite (Microline)
OKI ML 320 Elite (IBM)
OKI ML320 (Epson)
OKI Microline 320 Turbo
OKI Generic Dot-Matrix 9Pin Printer
Generic IBM Graphics 9pin
Epson FX Series 1 (80)
Epson LX/FX Series 2 (80)
We have a number of OKIs of varying age and I know some models vary in emulation hence the variety above. Typically the best we're seeing is each individual 9-pin line appearing upside down and back to front.
Has anyone had any experience with printing to these things from Windows client OSs to know what might work? I know we've been struggling with XP too.
The printer is in itself working, as an old system that runs atop Linux is fine printing labels to it.
