find attatched a short manual for Mapping a printer via GPP.
-Create a printer object on print server i.e. P_X555
-Create a local group "lg-prt-P_X555 Users" and give them Print acces on the printer object on the server.
-Create a global group "gg-prt-Map P_X555" and nist "lg-prt-P_X555 Users" in it.
-Create a GPO for printers i.e. "ALL Printers Location1"
-Delete Authenticated Users from GPO scope and add "lg-prt-P_X555 Users"
-Go to the server, right-click the printer P_X555, select "Deploy with Group Policy..." and browse to the created GPO "ALL Printers Location1"
Finally add users to "gg-prt-Map P_X555" and the printer will be mapped.
NOTE: For XP you must download the pushprinterconnection.exe and built a policy that points to the exe. Then add the local group to the scope of the policy.
