If your program wants an epson compatible printer, try configuring
thinkjet in 'Alternate mode' (I Think its switch 5).

Further, if in one of your programs, you get some graphics and then
garbage, most probably your serial flow control is not right.  There
are two kinds of handshake - hardware and software (x-on/x-ff)
handshake.  Try putting the printer to use hardware handshake.
Also you have to make sure that your printer cable is supporting all
the handshake control lines such as RTS, CTS, DTR.  

To prove that handshake is a problem, try setting both computer and
printer at 300 baud.  Now you may be able to get more graphics printed
and probably no garbage at all.

Most of the applications have drivers for thinkjet either in HP mode
or Alternate mode.
