I have an application that requires printing through the parallel port.
Normally, I could say something like
fprintf( stdprn,".....");
However, I believe that this will send output to LPT1. But, in my application, I
am using LPT1 to do other things (interrupt driven data acquisition). I need a
way of forcing output to LPT2 within the program. I have several TSR program
which would work, but I would like to avoid using them if I can.
Although my program does work (LPT1 for acquisition), LPT2 for printing, the
sucess of printing is unpredictable. Sometimes it prints OK, sometimes, it locks
the system. I suspect that part of the problem is related to the fact that I
don't explicitly force printing to LPT2. Am I right ???
Thnak you in advance
