1, the printer driver is not installed, that is, the printer is not installed correctly). In order to print, the printer must be installed normally. Generally, printers have their own drive disks, so we can choose the corresponding models for installation. However, many friends like to download drivers from the internet, which may lead to the installation of different models of drivers, resulting in the printer can not print. The solution is: try to use the printer driver that comes with the CD.
2. The printer is not powered on or online. Many times, when editors find that some office users can't print files with printers, it's because the printer's power is not turned on, or they may accidentally press the printer's related settings button and switch to offline state. These two low-level errors make natural printers unable to print.
3. The printer data cable is not in good contact or damaged. If you still can't print after simply eliminating the above two methods, please check whether the data cable of the printer is connected correctly and whether the data cable is damaged. Solution: Check the data cable connection between the printer and the computer host, and check whether the data cable is damaged.
4. The main printer is not set as the default printer. If you don't set the printer as the default printer, you can't print, mainly because a computer uses multiple printers, such as the common * * * printing settings. For example, if a computer has an application to print, it needs to use the printer installed on this computer, but we set the * * * printer as the default printer, which will cause the program to find the corresponding printer and naturally cannot print. This situation is also easy to happen.
