          In Your answer to my previous question, you mentioned that I
     probably have an inadequate power supply to run my STAR NX10
     printer, while on line and using MPP EXPRESS with my SUPRA 300AT
     modem.  My computor is a Std. ATARI 130XE, w/ a P.R. Connection
     for interfacing the printer to the computer.  How would I get a
     larger or more powerful one to allow me to print while being "ON
     LINE", or can you suggest a different way around this problem
     which would allow me to print while on line.
          Also is there a way to "LIST" or "COPY" a basic program to
     my printer when the program contains lines that have inverse
     characters?  Apparently my printer does not recognize these
     letters when they are received so the printer just locks up. 
     What I've been trying to do, is print a copy of AMODEM 7.2 to
     compare it to another version of AMODEM 7.2 which at one time I
     modified but can't remember what I changed.
          Hope you can help.

        In answer to the first part of your question, first check with Supra.
I have recently learned that some of 
the modem/printer problems were due to
defective modems.  After that has been
ruled out, either replace your main 5V
Atari power supply with one able to giveyou at least 2-1/2 Amps, replace the 
1-1/2 Amp regulator in the Atari supply
with a 3 Amp version, or add a 1 Amp supply between the ground and +5V leads of
the Atari std. I/O chain.
        Your second question has an easier answer.  Most printers, being set up
for ASCII transfer rather than ATASCII,
can't recognise inverse or graphic
characters.  The solution is to translate each character in turn to a printable
graphic pattern.  Fortunately, YOU need
not do it yourself; there are several
commercial programs that do it for you.

MAGNIPRINT from Alpha Systems and 
LISTER PLUS from Antic's Catalog are just two such.

                        Your Co-sysop

           Thanks for asking.
PS. Take this answer to a good Atari
service center if you need help with
the power supply hardware.
