I recently installed QuickBooks Pro2007 on a new laptop. At first, I was able to print invoices without any problem using a 24-pin to USB adaptor on an older Canon printer. Then in the last couple of weeks, I kept getting messages that the printer was off-line when there was nothing wrong with the connections. I assumed it might be a problem with the adaptor (I had heard they were not always reliable) so I bought a new HP Deskjet printer. Now I can print reports (so it's not a printer problem) but, when I go to print invoices, nothing happens. I have posed this question in the QuickBooksCommunity forum, but have not seen any satisfactory solutions so I thought I would post it on EE, where the real experts are. Can anyone help with this one?
