As far as I've been able to tell (I haven't tried to reflect the method) GetOutputPort simply returns the name of the printer.
Microsoft has put a lot of justifiable effort into abstracting printers to make printing in Windows very generalized. A trade-off to such a level of abstraction is losing some of the details. I think it's near impossible to generally limit printing to printers based on some hardware-level feature. If I encountered "Please use a different printer", I'd quickly move on to a different product...
