I think you are going to run into problems by trying to set up multiple operating systems. You have to make the partition where the operating system resides bootable (typically done by a utility program or Windows). So, I do not think it is going to work to have two or three partitions with different operating systems (the bootable portion of the disk is typically located in a certain place on the hard drive). You will also run into the same problem that you describe relative to Windows 10 (programs that are not necessarily designed to be backward compatible). A better option might be to go to the web sites for your printer and see if they have a Windows 10 driver. You can run older programs in a compatibility mode or see if they have updates on their websites for Windows 10.
