How can I get my QuickBooks POS 11/12 Lite to recognise another com port other than 4?
I have a new Posiflex PP8800 receipt printer which will work with QuickBooks on com 4 but the drivers cause a PCI memory fail and won't work after shutdown and restart. The computer is happy when it allocates com 3 to the virtual com port and will print a test page from my Windows 7 environment but this does not show as an option for selecting in my version of POS. My QBPOS options are Printer port on Customer Display or Com 4 only. Uninstalling and reinstalling the drivers and all the other USB drivers last and first and all other options don't work either.
