Running Peachtree for DOS on an XP pc, printing to LPT1 is unreliable, gets stuck.
Background: (in case it makes any difference)
-Peachtree for DOS (version 8 or 9 I think) being used in a manufacturing environment.
-Ultimate goal is to upgrade to latest Sage or QB for manufacturing, but for now, trying to move off of Win98 PCs to Win XP PCs and move data on a NAS.
-The configuration that is working: PTdos is on 4 Win98 PCs. #1: holds the data and shares it over network. #2,3,4 all access the data and are the main workstations.
-2 PCs print to their own LPT1 parallel printer port. an A/B switch box connects to two printers: an old HP laser and a tractor fed dot matrix check or invoice printer.
-This setup is rock solid for years
Trying to get rid of the Win98 PCs and use 1 generation newer WinXP PCs.
I've moved all PTdos data to a share on a QNAP NAS box.
All 3 WinXP pcs see and can open the Peachtree program from the NAS. I think that part is fine.
The problem is in testing printing. The XP PCs have parallel LPT1 ports. I move the parallel cable from the Win98 PC to the WinXP pc. XP 'sees' the laserjet on LPT1, so I direct it to the proper driver. It installs fine. I can print in Windows with no problem. In Peachtree DOS I can usually get one or more print jobs to the laser from PT. The problem generally comes when I switch the A/B box to the forms printer (dot matrix). I have sometimes gotten it to print, but oftentimes it takes a long time to print and many times it won't print. A job gets stuck in the queue. Clearing the job from the queue doesn't help. Stopping print service and manually deleting files from the Windows SPOOL folder doesnt help. I have to restart the PC.
I'm wondering if I should just not install any printer in Windows (the HP Laserjet on LPT1?) Is the windows driver for the HP Laser intercepting the print job intended for the dot matrix? If so, I'd think switching the parallel A/B switch back to the Laser should let it print, but it doesn't.
They do need to print to the laser from Windows so leaving it with no driver for the Laser seems like a problem.
