Today I'm programming an HP P4015 to get the DOS output formatted. It
appears to have a way to program that timer. Knock-wood.

Earlier in this thread I included information on changing a wait-to-print
item in Windows XP's registry. Something like that may be in Vista as well.

Here's TameDOS's web site....

fdapm is a power control I thought. What role would it play for printing?

What I'm saying I've seen a old DOS programs that typically are for use in a
specific industry or some specific regulatory. One was in the trucking
industry to track insurance expirations for independent truckers. Another
was for handling containers labeling paperwork which is handed to railroad
transfer agents. Given today's Internet there may be a way to generate some
business.
Note: Clipper always needs tuning, particularly for the program of current
disgust. I used the Blinker linker and it has a good DPMI. I turned off
EMS and XMS and set memory to auto. DPMI is set to 8192 but a Blinker
memory function reports that 45,000k is available.
It has been a while since I looked at the link scripts. I got the Blink
link script right by trial and mostly error having used a dozen third party
libraries. If I were to change something it would take days to test and
qualify it.
Cheers
