install printer as network printer. meaning the port is set to the remote computer for example \\computer\laser.
Now call up a dos prompt, do a:
net use lpt1: \\computer\laser <-- this maps network printer to lpt1
now hit properties on the printer, hit port tab, change port to lpt1
now printer should be mapped when you rdp to the terminal server.
if the printer does not show up in quickbooks but does show up in other programs, the printer name is too long. Shorten the name and it should show up in quickbooks.
