Question

Why would you create virtual printers and very the priorities on them???????

Answer 1

to emulate printing.
You can print to file on one specific type of printer, this will create a .ps (postscript) or .eps (emulated postscript) file that can be distilled to a pdf document, or downloaded directly to a printer. Priority just enables the document to go somewhere else if one printer is busy or not functional
