Way to ungroup printers when multiple printers share the same IP/port?
Solution 1:
For a clear view without changing config another answer is here (Alan) - http://social.technet.microsoft.com/Forums/en-US/winserverprint/thread/eb0ae4cd-38d0-4b9d-b9f3-838391b6a399
We use multiple queues to allow drivers suited to different purposes - PCL for docs, PS for CAD. XPS promises to supersede both. ProfAm's presets are another feature people ask for, but we don't do that here.

Solution 2:
We use the same setup at many of our sites, it's also useful for limiting who can print in colour (install the printe rtwice, one as B&W and one colour and give appropriate people access to colour), and as you have stated, for assigned trays etc.
The quick fix is to add a seperate port for each printer, It doesn't group by the actual port address, just the port name.
