Most of the Okidatas from the period (Microline 320,
520, etc.)
had a standard Parallel port built in on the back of the printer.
Right next to it is usually a plastic knockout.
If you get the RS232 serial port option for this printer,
you remove the plastic knockout, and slide the RS232 board
into the opening. There is a card-edge connector that
it mates with.
You don't have to set any switches to use it.
Ok, then in that respect it's different than my old 92...
I don't really know if it will let you do
"dual porting" or not.
(i.e., 2 computers printing to it, one via serial, one via parallel.)
I have a major pile of those 3xx printers and no docs on them at all.
As for the RJ45 adapter; those are fairly common. The
serial port probably
only needs 3 pins for printing, Ground, TXD, and RXD . . (7, 2, and 3),
although they may have included handshaking signals. Who knows.
Yeah, a hardware handshake line or two is a nice thing to have.
A standard serial cable to/from your computer should
work,
as well as a parallel cable.
Documentation should be readily downloadable
from the Okidata website.
I'll have to have a look, then.
One other oddity I noticed on that particular printer is a "slot" in the front
of it. Might be for some sort of a font cartride maybe? Darned if I know...
