Oki Ml 5520 may sometimes be at fault for other drivers ceasing to function These are the driver scans of 2 of our recent wiki members* *Scans were performed on computers suffering from Oki Ml 5520 disfunctions. SOURCE: okidata 320 turbo microline prints jibberish sounds like a job was sent to the printer with the wrong driver. There is no way to purge it just load some paper and let it run until it stops. The document below provides details of the compatibility of OKI printer drivers with Windows 10. This will continue to be updated as and when drivers become available.

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 microline 490 printer OKI ML 320 Elite (IBM)
OKI ML320 (Epson)
OKI Microline 320 Turbo

Oki Microline 320 Turbo 9 Pin Printer


OKI Generic Dot-Matrix 9Pin Printer
Oki Generic IBM Graphics 9pin
Epson FX Series 1 (80)
Oki Microline 5520 Driver For Mac 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.

Oki Microline 421

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.

Oki Microline 390 Turbo

Thanks.
