Re: print directly to lpt1, like in dos

Rick,

This is the very thing I'm trying to do too. It seems to me that there
must be a way to do it. The LPT1 driver must be callable, otherwise how
can the printer drivers and spoolers send data to it? I've tried BIOS
calls but they crash the system. I've also tried opening LPT1: and PRN:
as files or Comm devices but that doesn't work either. I will grant you
that it is a well guarded secret since most terminal emulators do not
support it either. Yet it must be doable.
