How to properly connect the EPSON LX-350 printer to the RS-232 interface?

Question

Epson

Good day, dear users of the resource.
How to properly connect the EPSON LX-350 printer to the RS-232 interface?
Namely:
- pinout from the side of the printer and from the side of the interface card. From the side of the printer
EIA-232D (25 pins), and the side of the interface is 9 pins, but what is there and where ..?
- printer settings (baud rate, parity, data length) whether it is possible to poke at random without consequences.
Drivers are probably not needed, since the interface card has nothing to do with Windows. Although the whole monitoring system is a Windows application. The whole system is connected by LAN RS485. The host computer has special network cards installed for this, but the printer does not connect directly to the computer.
I would be very grateful for the help. e-mail to every fireman [email protected]

Well, I'll try to shake up the old days ... I remember that they almost always used a simplified connection pinout, with a 3-wire cable (it's easier to solder it yourself):
However, no one bothers to make a complete one:
But actually, Yandex is to help!

printer settings (baud rate, parity, data length) whether it is possible to poke at random without consequences.

You can poke (COM-port - it is unkillable, in case of incorrect settings there will simply be no connection), but as far as I remember, you just need to make the same connections from both ends. Set the speed to 64 or 128 Kbaud, this is enough for a matrix.
