Another odd one. I just upgraded four computers from XP to 7 home. Another computer didn't have the specs for 7 so we replaced it. The replacement computer has 7 pro instead of 7 home because I couldn't find a computer with 32bit 7 home. It had to be 32 bit because of the Point of Sale program that will run on the computers.
The computers with the home version the POS program works great. With the computer that has 7 pro the program only mostly works. When creating a ticket on the POS program everything goes smooth unless the transaction is a cash transaction.
In the program you enter the customer information and then enter what they purchased. Tab down and you get a choice of paid in full yes/no and then method of payment. When the method of payment is anything but cash everything works and you have the option to print the invoice. When cash is selected the program freezes for about five minutes then just prints an invoice without giving the option.
Same POS program and same settings on all computers and doesn't matter if printer is on or off.
The only other difference is the 7 pro computer I had to put a parallel port in the machine to connect the printer and the others the parallel port is attached to the motherboard. The printer works though outside the POS program and also prints everything in the POS just takes to long to print cash invoices.
Anybody have any ideas what might be different in pro compared to home edition that could be causing this problem. I know it has probably been a long time since anybody had to play with DOS programs but right now having them update the program isn't an option so I'm kind of stuck scratching my head.
