My name is Alex. I have 6 years of experience in resolving QuickBooks issues. Often the error ‘QuickBooks won’t print’ occurs when there is a connectivity issue. Thus, first, check if your printer and computer are connected to the same network. Also, the network is working fine. Next, try changing the filename to see if the issue is with a specific file or not. Besides, check your printer driver. The printer driver should be compatible with your operating system or you may have to reinstall them.
