I have a question concerning the use of an Imagewriter I as a general
purpose printer.  I recently bought a PC compatible (second computer,
first was a Mac). I would like to be able to use the Imagewriter as a
printer for the (non)IBM, since I don't want to spend the bucks on
another printer.  Any and all information on what signals the PC sends
out and what the Imagewriter expects will be greatly appreciated. By the
way, I am also doing some research in external sources myself. Either
followups or resonses or email are great, and I will post a solution
once I have the printing going.

Thanks in advance

The imagewriter accepts the same control commands as the C. Itoh printer
that it was originally sold as.  It is a stock RS-232 DTR device, doing
DTR handshaking using pin 20, in its Mac configuration, although it can be
jumpered to uses ^S, ^Q handshaking.  Appple has even published a
tech-note giving the pinouts for connecting it to an IBM PC, and the
information is repeated in the manual that comes with the ImageWriter.
The IBM expects to see handshaking on pins 5,6,and 8, so jumper them
together in the IBM side of the cable.

In general, you will find printers that use a serial interface,
Imagewriters, LaserWriters, Diablos, Spinwriters, and HP LaserJets, all
use Xon/Xoff for flow control.  Some of these printers, Imagewriter,
Laserwriter, and HP LaserJet can be modified (easy as flipping a dip
switch on some), to use DTR (DSR??, pin 20 I think), for flow control
the same as the IBM PC.  Some PC's can be configured to use Xon/Xoff
for flow control, like the Zenith PC's.

So beware, if you have a serial interface between units and they cannot
keep up with the line speed, make sure they use the same process for
flow control.

Of course, dip switch 2-3 decides whether the IW uses X-on/X-off
(default) or DTR for flow control.
