Oki ML590 Serial Interface Board Issue

UNIX SCO
1

Hi

Had an old ML590 with RS232 serial card that stopped working (spindle that advance ribbon broke) so I purchased a working used on ebay.

Printer powers up and seems fine. Put serial board from old printer in working ebay unit but no printing happens.

Does anyone know if there are any jumpers or switches needing attention in printer that never had this board in it before?

We're running SCO Unix with Real World accounting. I know there are port setups in Unix but I was thinking that this new printer should just work with board slipped in.

Any knowledge out there?

Thanks

Did you set the baud rate the same as the old printer? You have to do it through the printer front panel set up menu.
You also have to set the serial board as the active interface.

Thanks for the reply, that makes sense. Looking for the old manual to that printer.

Are those changes more than the basic user manual would cover?

The instructions are in the user set up manual. Also covers things like default font and lines per inch.
You should probably also set the "CR on LF" option as well to avoid "staircased" printing (ie a subsequent line starts directly below the last character or the previous line.)

abcdefgh
              ijklmnop
                           qrstuv

instead of

abcdefgh
ijklmnopq
rstuv
