Answer:
The most likely reason would that the printer is low on toner
Explanation:
Ordinarily some printers display a message confirming that their toner is low especially the toner would be likely exhausted anytime soon.
One can also confirm if no warning message is displayed through the printer setting icon on the system to be sure the toner needs to be refilled or replaced.
Another point is that the makers of printers such as HP have readily made toners available for sale that could be used to replace exhausted toner in a twinkling of an eye.
