When there’s a problem, the files just remain in the queue. The spooler is useful as it enables you to change the order of pending print jobs or delete them.
They arrive first in the spooler, which is a program that manages all print jobs. In Windows, the print files are not directly sent to the printer. No error message is received, and yet the status remains “Printing” indefinitely. You try to print several other files to see if printing would start, but they all get lined up. It can be frustrating when you want to use your printer but a previous document is in the queue. Developed for Windows 10 (8, 7, Vista, XP)
