20 Most Recent OKI MICROLINE 591 Matrix Printer Questions & Answers

Usually when this printer prints in HIGH QUALITY, it will only print one way, to avoid misalignment issues between the one pass one way and the next pass coming from the opposite direction.

If I am right, lowering the quality of your print to "normal" or "draft" should give you back the "2-way printing"

Hello there
This may work for you, it has worked for many here I given this advice so gave it a try it could work for you. Generally when this happens, something has fallen into the printer, or a piece of paper has been jammed in there.

First step, remove the ink cartridge, and turn the printer upside down and gently shake it, see if anything comes out.

If nothing goes, or you can't hear anything rattling around, get a piece of cardstock paper (60lb or heavier) and gently push this through the printer, to see if it will help push out what might be stuck in there.
And gave the rode that the ink slides on a good clean and maybe a bit oil on cloth and wipe the rod with it.

Please come back and just gave a vote, it will gave me some satisfaction to know am helping some one so I will keep on helping.

Unplug the power.
Remove the ribbon cartridge.
Look at the left hand side of the ribbon mounting plate, at the 'T' shaped ribbon drive shaft.
Now grasp your printhead, and gently move it about 10-15cm to and fro.
Can you see the ribbon drive'T' shaft rotating?
if not, it is probably worn out or damaged.
It will need replacing

The drivers should be on the company website, if these are not working for you the generic text driver in Windows will work for text only printing. If you do graphics or formatted invoices, etc. on the printer Epson and Okidata both make pretty generic print drivers that should work for a microline printer.

First thing to try is turning the printer off and back on again. If it still continues, replace the printer cable.

it's in the print settings..open up your print manager, and you'll see a button..for that..my profile has contact info if this doesn't get you there.

You need to set and store paper size, width etc in printers internal menu and on print driver on pc.
See Oki manual for printer settings its written on the front of the machine i think menu and set power on, then print to see settings then read manual...

use the HP laserjet 4 or 4000 print driver. this is the most basic print driver and has played nicely with the older printers
