hi,

i've got an NEC silentwriter model 95 printer.  it's a postscript
printer that also has HP laserjet III emulation.  unfortunately, the
switching is done in software or from the control panel -- there is no
auotdectect in hardware as to whether it should be in postscript or
LJIII mode.  I've got the codees required to switch modes, but i'd like
to be able to have a program that monitors the printer port and check
the frist 2 bytes of each job to see if it's a postscript or LJIII file,
and changes the mode of the printer.

so the question is:  what's required to do this?  is there any hope of
getting a dedicated printer driver that incorporates auto-switching?  i
find this unlikely.  so the question becomes:  how does one write a
program to do this?

also, shen i tried to install the laserjet III driver, i wanted to put
it also on lpt1, and it's not happy with that.  what's the best wya to
have both printers being able to access lpt1?  having them print to a
file, and specifying lpt1.os2 as the file?

any help much appreciated.

thanks in advance!

andy
