You are the administrator of a Windows 2000 Professional computer that has a shared printer. Several departments in ExamSheet use the shared printer. Thesalesdepartment frequently prints multiple-page presentation graphics, which take a long time to print. Users in other departments who have short messages to print must wait an unnecessarily long time for their jobs to print. The permissions for the shared printer are shown in the HP Desktop 722C Properties dialog box.  You want to improve the efficiency of printing for all users who use the shared printer. You want to accomplish this with the least amount of administrative effort. What should you do?（　）

• A、Configure the priority of the printer to 50. Add a new printer that prints to the same print device，and leave the default priority setting. For the original printer， remove the print permission for the Sales group.
• B、Configure the priority of the printer to 50. Add a new printer that prints to the same print device，and set the priority to 25. For the new printer， remove the print permission for the Sales group.
• C、Monitor the print queue， and raise the priority of all the print jobs that are sent by users who are not members of thesalesdepartment.
• D、Delete the old printer. Add a new printer that prints to the same print device， and set the priority to a higher value. Pause the print queue only when graphic-intensive print jobs are printing.
