I have two printers attached to my Leading Edge Model D, as follows:
    LPT1: dot-matrix
    LPT2: HP Deskjet
For most printer output (e.g. screen dumps, ho-hum reports, etc) I want to
use the dot-matrix printer.  When I want fancy, I go to the HP.  Things of
this nature are produced by software smart enough to recognize printers not
on port LPT1:.

This euphoric state has been disrupted by a music score-printing program (Dr.
T's Copyist II) which only talks to the LPT1: printer.  I can easily switch
the cables, but this defeats using the dot-matrix for most other instances
where this is more than acceptable.  

Can I get LPT1: output to go to LPT2: for the purposes of running Copyist?
Mode won't do it - the rerouted port must be com1 or com2.  Print can change
the DOS print device for the purposes of the print command, but nothing more.
I have DOS 3.1, by the way.  Would a later version of DOS offer what I want?
Can I do it now without upgrading to a more recent DOS?

Any info is appreciated.
