Connecting to an RDP / Terminal Server from a Mac can be a little hit and miss. This is because the RDP protocol keeps changing, and Microsoft don't update the Mac client to keep abreast of this.
Using CORD makes this significantly easier: http://cord.sourceforge.net .
This will allow you to connect easily, and forward local printers etc.
CORD will use the "HP Colour Laserjet 8500 PS" as the generic driver to pass through to the server however. This driver is not available for Windows Server 2008 R2, so you need to engage in a little trickery.
- Install a universal HP PS driver (search for Colour Laserjet 4350n Postscript driver) - found here
- Create a custom printer redirect mapping file and a couple of registry settings. Good Microsoft Article on how to do this found here
Example File contents: c:\windows\inf\ntprintsubs.inf
;Printer mapping file for client-side to server-side drivers
"HP Color LaserJet 8500 PS" = "HP Universal Printing PS"
"HP Color LaserJet CP4520 Series" = "HP Universal Printing PS"
You need to put this in c:\windows\inf and create the two registry keys described in this article: (these are the values I used)
Create new REG_SZ key #1: PrinterMappingINFName
Create new REG_SZ key #2: PrinterMappingINFSection
