I don't know why anyone still uses iem.kug.ac.at... is it an old address?
Anyway, I re-send my reply just in case it's not getting through.

First you need to install the [comport] class or any equivalent. It's best to
use my hacked version because none of the other versions can't handle
flow-control properly.
Second you need to figure out the wire protocol. Serial port is called serial
port because it's using the RS-232 protocol, but this protocol has many
variants and they are not autodetected. For example, you may have to say: speed
9600 bits/second, 8 data bits per byte, 1 stop bit per byte, no parity, CTS/RTS
flow-control.
Third you need to figure out the application protocol. The printer's manual may
say, for example, that it's an Epson-compatible printer, or it may have a
switch between Epson-compatible and a different mode. Old manuals often give
you a list of all commands you can do on that printer, especially because they
often offer extensions to the standard protocol they are basing themselves on,
or sometimes because they have a completely different protocol.
Most of those printers are based on escape-sequences starting with the
escape-code ("ascii" # 27), which may sound familiar, but those sequences are
not related with any of the screen-and-keyboard escape-sequences (VT/ANSI) used
on BBSes and unix operating systems.
