Later, TRS232 came out with a trivial to use serial
printer interface that
ran off of the cassette port! GPA made a similar one that plugged into
But which presuambly needed special drivers that were OS-dependant. At
least with the Radio Shcak board, you could use the standard LDOS serial
port drivers.
the expansion port.
I suspect, had I been desparate, I would haev hung a parellel-to-serial
converter (a handful of TTL chips) off the normal printer port..
Alas (for
those of us with CX engined printers which can't be replaced by
anything more modern [1]), they haven't been made for many years.
[1] Such as the CX-VDO, the one with the direct interface to the print
engine and no formatter board. It's used on the PERQ, Atari ST (?), Acorn
Archimedes. etc.
Also Cordata/Corona Data Systems, Eiconscript, and Jlaser
I used a DC37 switch box.
Tall Tree Systems (Jlaser, JRAM, etc.) sold an adapter to connect to SX
printer engines!
There was an official Canon SX-VDO printer. It had a simple PCB (mostly
buffer chips) that connected to the DC controller board in place of the
formater. It was mostly compatible with the CX-VDO, but not totally IIRC.
Some compnay (I forget who) did a VDO interface that fitted in the
optional interface slot of an HP LJ2 (or similar) printer. I have neve
seen this one.
