[comp.sys.ibm.pc.misc] print slave must die!

jes@mbio.med.upenn.edu (Joe Smith) (07/28/90)

We have a PC which isn't connected to any printer (either parallel or
serial).  Of course, every time some unsuspecting user accidently hits
^P, the poor PC is hung as DOS tries in vain to slave the printer, and
the poor confused user comes running to me for help.

Does anyone know how to kill (with extreme prejudice) this 'feature'?
I generally shy away from patching binaries, but I'm willing to make
an exception here if necessary.

Do the PD printer->file TSRs/drivers handle this?  If so can you
recommend one?  This might actually be the most desirable solution
since we do all the printing remotely by tcp/ip so we frequently
need to capture printer output.

Does anyone know why this mis-feature/vestigial tail still exists?

Here's a quick *hardware* solution to the "no printer hang".

Get a male DB-25 connector. Insulation displacement type works well
for this. Run a piece of hookup wire from pin 1 to pin 10. Snap on
the back of the connector. Now plug it into the printer port.

You now have the worlds fastest printer. :-)

In case you are curious, what you've just done is connect the
STROBE line to the READY line. So as soon as the computer asserts
STROBE [data ready for printer] it gets READY [printer ready for
more data]

We've had to use this to get a few machines to be able to rediirect
PrtScr to a network printer.
