Your office printer was working earlier in the day but is no longer printing any documents. Pre-existing workstations are manually configured to print to the printer directly over the network. You begin troubleshooting the problem and determine that the printer is still visible when browsing the network directory. You also verify, at the physical printer, that the printer can print test pages successfully. Which of the following is the most likely cause of the problem.
A. The printer spooler was restarted.
B. Two users sent print jobs at the same time, which cause a collision.
C. The printer's IP address has changed.
D. The message "perform printer maintenance" is displayed on the printer's display panel.
