Motorola Printer Barcode Standards?

There are two common printing models which currently appear to be NOT supported by the print API?

Will they be suported in the future?

#1. Define an IP printer by it's hostname (and not IP address) - direct printing model.

#2. Define an IP printer by it's hostname and queue name (LP printing model) - In this the printer's hostname is the name of the print server and not the name of the printer.
