Question 10

A user received a new workstation but is unable to print successfully to the shared network printer. Other users are able to print without issues. Some recent OS updates were applied to the workstation, and all other services are working fine. The technician checks the printer's properties and notices it is configured for LPT1. Which of the following should be performed NEXT to troubleshoot the issue?
A) Update the printer description name.
B) Clean the print heads.
C) Restart the print spooler.
D) Configure a new printer port.
