When I print I cannot stop it from printing c% each time. How do I stop this?

cancel the print spool..

I have to do this every time I try to print more than one job. Why is this happening? It is very time consuming to restart the pc every time you have to print more than 1 job.

maybe have a look in the settings and change the priority setting to right now or urgent or something like that

Would be helpful to know which operating system you are using and whether there where any warning light flashing. For starters review the following solutions.
Printer Does Not Start or Stops During Print Jobs

Inner Cover was open when you started printing.

Close the Inner Cover and press the RESUME/CANCEL button on the printer. The printer resumes printing.

Inner Cover was opened while printing is in progress.

Close the Inner Cover and press the RESUME/CANCEL button on the printer.

A page of print data being sent at the time of the error will be erased, so print that page again.

The printer has been printing continuously over a long period.

If the printer has been printing continuously for a long time, the Print Head may overheat. To protect the Print Head, the printer may stop printing at a line break for a period of time and then resume printing.

In this case, interrupt your print session at a convenient time and turn the printer off for at least 15 minutes.

Additionally, if the printer has been printing graphics or photos with intense colors continuously over a period of time, the printer may stop printing to protect the Print Head. In this case, printing will not resume automatically. Turn the printer off for at least 15 minutes.

Caution

The Print Head and the surrounding area can become extremely hot inside the printer. Never touch the Print Head or nearby components.

Out of paper.

Make sure that paper is loaded in the selected paper source.

Reload paper if no paper is found in the selected paper source (Auto Sheet Feeder or the Cassette).

If the same paper is loaded in the other paper source, you can switch the paper source with the Paper Feed Switch or the printer driver to continue printing.

If both paper sources have run out of paper, confirm the selected paper source and load paper there.

Printing documents with plenty of photographs or illustrations.

When the POWER lamp is flashing green, the printer or the computer is processing data. Printing large data such as photos or graphics takes time for the printer and the computer to process, during which the printer may appear to have stopped operating.

In addition, when printing data that uses a large amount of ink continuously on plain paper, the printer may pause temporarily. In either case, wait until the process is complete.

Note

If you are printing a document with a large printing area or printing multiple copies of a document, printing may pause to allow the ink to dry.
