Recently I installed Windows 10. But: my printers are old, so(!!) they do't work under W10.
I want to try printing under W7, without leaving W10. On this moment I need tot close W10, restart, choose W7 and print my document. Then restart, choose W10 and proceed.
Can I use Virtualbox?

Perhaps. Controlling physical hardware is not the forte of a VirtualBox machine, but some have managed it. I assume that the printer has a USB or network interface.

Others just get a new printer - and choose a better manufacturer, i.e. one who will support their printers well into the future.

Microsoft have said that Windows 10 is the last version of Windows, so it probably pays to get Win10 drivers.
