Problems about adding printers by terminal server users.
Look that adding printers by user create a redirection only by network(if the printer is reachable from the terminal server). For example it is the case of adding a local(to the term server) printer or a printer in another network reachable from the local(to term server) lan.
Using the power of terminal services delegate the printing services to Windows terminal services instead of manual configurations.
An useful trick is press F5 on the window Printers and Fax after logon to terminal server. Sometimes the update process of Printers isn’t fast.
