TRS80 Model 3 i/o connectors (printer support)

About printers:

The one thing to remember about the TRS line is that
the printer output is not emitting <CR><LF> pairs but
rather <CR> with implied <LF>, so most of the
DOS-centric printers will be unhappy. (<CR> is
shorthand for the carriage return character, ASCII
code 13 decimal; <LF> is linefeed, ASCII code 10
decimal)

You used to be able to tell printers that they should
interpret <CR> as <CR><LF>, but I don't know if the
newer ones will still do that.

Or, you can set up the TRSDOS O/S to add them in (at
least under LSDOS/TRSDOS on a Model 4).

It's been awhile!
