There are two ARexx command files named TexPrtInit.tpr
and TexPrtPrint.tpr. The first one of these is executed during startup
in the case where TEXPrt detects that a message port named TeXPrtPort
is already open. The TexPrtPrint.tpr which I have included simply pops to front
the public screen and TEXPrt's window. The second
file TexPrtPrint.tpr is executed when you have confirmed the printout.
If ARexx is running on your machine this is all what is done when the printout
is confirmed. So if you really want to launch the printer driver in this case,
you must send TEXPrt the
command PRINT via ARexx. I have chosen this mechanism for flexibility reasons.
For example, the TexPrtPrint.tpr ARexx macro that comes with this archive
looks if the ShowDVI previewer is running, and if so, it requests the current
DVI file from the ShowDVI program and sends it to TEXPrt. After that
it sends a PRINT command to TEXPrt to launch the printer driver.
If ARexx is not running or if you don't have ARexx (which I can't believe),
the printer driver is launched directly without using ARexx.
