What if Canon printer prints slowly?

If the printer's printing speed is getting slower and slower, and the system's response starts to slow down, I think it should be your system's problem rather than the printer's problem, which may be caused by the small cache of your system. As we all know, when the printer works, it sends the printed contents to the system background for caching, because if the file is too big or too big, your printer memory can't hold all the contents you need to print. At this time, the system needs to put it in the cache and transfer it to your printer bit by bit. Everyone has the feeling that the longer your system is used, the more garbage there is, and the slower your system will be. In the cache directory of WINDOWS system, it has a suffix. DAT in some specific directories is a record file automatically generated by the system. These files record all your use of the system. At best, they speed up your browsing or opening. Worst of all, once you open such a file with a special program, all your actions using the computer are lifelike! The total occupied space is amazing! But ordinary cleaning software can't clean it, because there is system protection. Recommend a good thing that can completely clean up this dangerous garbage: track eraser Pro.
