Recently upgraded to Windows 10 from 7 about a week ago. Initially, I was able to use the built in "Microsoft Print to PDF" option when I wanted to save a file to my computer. At some point however, this option disappeared from the printer selection drop down of the printing dialog. I also got a new printer recently (which still works fine), but I went through and deleted all the random old printer drivers. I don't remember seeing a Windows driver (other than XPS writer, which is still there) but maybe I removed the "Microsoft Print to PDF" driver? If so, I can't find anywhere on the computer or the web to add it back to my device list.
Thanks for any help!
