Have had Parallels 13 running on Mac Mojave and VM Win 7 32 bit. The Win 7 is intended to run one program that has been designed for windows and has no other usage but to print from that program. We had done an upgrade to a newer MacBook Pro and reinstalled the system via Time Machine ( I had to re-license Parallels, but anticipated that). Everything had worked fine under the previous MacBook. We had an a touch older HP printer that failed and (with the printer crunch) got an HP LaserJet Pro MFP M227fdw. Mac installed fine using the HP software. I could have used the Mac driver, but wanted the scan utility. Windows installed it as a HP 2800PS (why post script- I have no idea on that emulation). It will not print with that configuration (indicates it is creating a PS file and then just disappears and never gets to the printer queue). So I installed with Win HP drivers to have it the same as the MAC printer and it will not print at all. So went to the help guides and installed Bonjour services for printing. Worked for one day and then stopped and no printing will come from the Window's side. I have gone into the configuration of Parallels and everything is set as it should be. I even unchecked all the necessary items and rechecked in case there had been a corruption. The printer is being shared on the MAC side. I have reinstalled the the tools, but no change. Have even gotten, from unplugging the USB connection and re-plugging it, the frame which asks whether I want to connect to Mac or Windows- choose windows and still no printing. What gives and any suggestions are welcomed.
