|Thanks for the replies everyone.|
To add to what Seawatch said, many HP & MFPs could not be shared over a network. In the beginning there were NO Lexmark USB printers that could be shared. (This was confirmed with Lexmark).
The issue was that you could share the printer as normal, BUT you would not be able to see it, or connect to it from other PCs. (Like it wasn't there at all).
