I have the latest version of Parallels 13 running the latest version of Windows 10 on the latest version of Mac OS X. All software is up-to-date. I can print fine from my Mac to my two connected printers (Canon imageCLASS MF244dw and HP OfficeJet Pro 8600 Plus), but whenever I try to print to either printer in Windows the printers will only print double sided. All double-sided print features are off on the printers and in Windows print dialogue boxes. I want to print one side per page. Please help -- this is not a printer issue per se, this happens only when I am printing from Windows running in Parallels.
