Subj: PRINTER HELP PLS

I picked up a couple of the old 80 column Big Blue/Protecto thermal
printers...because the price was right.  No documentation though, so I need
some help!  I see they use GND, CTS and RXD and those are the only wires coming
from the print cable.  One printer has bare wires, and the other has an 8x2
Amphenol DIP female connector on it.  What I need to know is the protocol for
communication.  Does anyone remember what they used? 300 buad 8 bit No parity 1
Stop Bit?  I've tried lots of combinations and can't seem to get the thing to
print anything intelligible.  Thought it would be faster to ask someone than
keep switching the TERMINAL program STATS around!  It does print...but nothing
intelligible.  Does it use the standard ASCII character set?  I don't see any
internal EPROM in there which might make it machine specific.  ANY help would
be appreciated.
