Hi All,
I have a multithread NT4 sp3 app that needs to respond in near real time
weighing and labeling cartons @ 20/min then recording the data into dbase
tables. The app is running on Pentium 200 Pro with 64Meg Ram,scsii hard
disc.
The problem is when it prints locally to the parallel port, the print
spooler slams the CPU with 100% CPU utilisation (using Epson LX300 or
generic/text only driver) and does not get back to to my app fast enough.
I can not transfer the printer to a serial port at the moment as all four
serial fitted to the PC are in use and I can not network it to another PC as
the print out has to be beside where the cartons are being weighted and
labeled (even though this works).
The barcode printer which is on a serial port does not cause any problems.
Has any body got ideas other than fit more serial ports.
At this point I do not wish to up the app priority to real time as it must
work hand in hand with three other apps on the same PC.
