the<br />
:.<br />
serial (RS-232) port on the ST, as they should.<br />
Now you have a choice as to whether or not the "Mac<br />
: :<br />
printer port" (the one on the Mac marked with the little<br />
printer) talks to the <strong>Atari</strong>'s serial or parallel port; usually, it's<br />
parallel, but you can force it to serial if you need to for a serial printer,<br />
like the ImageWriter.<br />
Of course, then you've got a problem! Anytime the Mac talks to<br />
the Mac modem port, it will output to the ST's serial port, and anytime<br />
the Mac talks to the Mac printer port, it will also output to the ST's<br />
serial port. If you don't have the proper device connected at the proper<br />
time, you're going to have trouble. Or garbage. Or something.<br />
You cannot get away with having both a modem and the printer<br />
hooked up to the serial port at the same time, even with a three-way<br />
cable. The modem and printer will "fight" one another for control, and<br />
whoever loses sometimes loses with a blown driver chip. Please don't<br />
try. It's also not good for cables and tempers to swap back and forth<br />
all the time.<br />
If you have to use a serial printer and serial modem, please get an<br />
"AlB switch box", and manually switch between devices when you<br />
need to. CompuAdd sells those boxes for about $14. It's much more<br />
convenient than swapping cables around. For instance, you set the<br />
switch to the modem when you're in a telecommunications program;<br />
then switch to the printer when you need to print. That way, only one<br />
device is hooked up to the ST at any one time. (I use one of these on<br />
my ST, and it works quite well.)<br />
This is all further complicated if you dccide to use an <strong>Atari</strong> Laser<br />
Printer, but l'll leave that for latcr.<br />
The Software Part of Printing<br />
A whole manual could be dcvoted to the art of getting the Mac to<br />
print something, especially and particularly if you're not using an<br />
A pple-manufacturcd printcr.<br />
As I mentioned earlier, the Mac is very "dot" oriented; to print<br />
something, it outputs a string of dots, specially coded, to the<br />
ImageWriter. The ImageWriter then puts the dots on the page, and if<br />
everything works right, the dots form letters (if you're printing<br />
