(cannot see all the Print2RDP printers in the Devices and Printers dialog on Windows Server 2008)
This is a new feature of the Windows 2008 R2 and Windows 7 operating systems. The printers using the same port and driver will be displayed in one group in the Devices and Printers dialog.

A workaround is available which will show all the printers separately in a custom folder which will reside on the desktop. To do this, a new registry key needs to be added.
Open the registry editor and navigate to the following location:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Desktop\NameSpace
Right click on NameSpace and choose ‘New Key’
Name the key: {2227a280-3aea-1069-a2de-08002b30309d} …be sure to include the {brackets}
In the right pane, edit the value of ‘Default’ and change it to ‘Printers’:

Close Registry Editor and refresh the desktop. A new folder called ‘Printers’ which will show all the printers separately.
