The USB printers function on the host computer, but not yet on the guest OS. I have enabled the USB controller and if I click on "Filters" I do see that both printers appear as options.
If I click on Devices >> Printers in the Virtual Machine, I am given a screen which asks for drivers. I install those drivers and it seems to progress fine. However, if I go to the Printers folder in my control panel, it shows the printers as "offline"
If I click on Devices >> Printers in the Virtual Machine again, I am given an error message.
In short, I am stuck. I've been reading all day, and it seems that the steps are fine, but it still does not work.
