I am thinking about writing a TSR program to redirect output from LPTx
to disk and store them into *separate* files, instead of appending them
into one big file.

I have a good idea on how to use int28 to do background work and int17 to
capture LPTx.  However, I don't know how to detect the start and end of
a printed document when there are multiple ones being sent to LPTx and
possibly being sent from different programs.

For example, if a user prints Doc1 to LPT1 from WordPerfect and then prints
Doc2 to LPT1 from MS Word, when I capture LPT1, how do I know if Doc1 is
being printed(so that I can redirect it to a file called temp1 on disk)
and if Doc2 is being printed(then I can call it temp2)???  

Is this possible? or am I forced to write some kind of a device driver to
capture the output?

Thanks in advance,
