If Bidirectional Communication is Disabled

Under Windows 2000/XP/Vista and Windows Server 2003/2003 R2, Manage Printers permission is required to change the printer properties in the [Printers] folder. Log on as an Administrators or Power Users group member to acquire this permission.

Make sure that [Enable bidirectional support] in the [Port] tab of the printer properties is selected. The machine cannot print if [Enable bidirectional support] is not selected.
