I have been troubleshooting an issue with QuickBooks for one of my clients. Initially, I was asked to look into a printing issue, but upon investigation, I found that QuickBooks was hanging and/or locking up when saving new invoices. After some work, I managed to get it running where it would occasionally get stuck but eventually move past it in a reasonable amount of time and then print.
However, my client decided to swap their printer back and forth with another one. Now, when printing two or more pages from QuickBooks, it pulls a third blank page in between the two prints. I spent some time troubleshooting this yesterday. I called today and found out that they had swapped the PC with another Counter PC, and now both computers have the same issue regardless of where they're plugged in.
One last thing of note: Both PCs show no signs of printing issues or network issues outside of QuickBooks.
