The reasons why the printer cannot print include: printer cable failure, system infection virus, printer driver damage, printer port setting error, disk free space less than 10 MB, no main printer set as default printer, printer not online, printer problem, printer out of ink, computer background shutdown.
1. The printer cable is faulty
If the computer and the printing press are connected indirectly, we must connect the computer and the printing press.
2. Systemic virus
If you are infected by a virus, it will not print out. You can use anti-virus software to kill viruses.
3. The printer driver is damaged
The file could not be printed due to a failure in the printer driver. Reinstall the correct driver before printing.
4. The printer port is not set correctly
5. Printer port error, as shown below:
A. The printer cannot print because the printer is not online.
B. The printer is not printed and cannot be printed.
C. The local printer port is set incorrectly, which makes the printer unable to print.
6. The memory on the hard disk is less than 10 Mb
When you do not have more than 10 MB of hard disk available, you need to make more space for printing.
7. The main printer is not set as the default printer
Usually, you have multiple printers, and this printer is often used, so it is the default, not the default. Then the program cannot find the corresponding printer, and of course it cannot print.
8. The printer is not online
Many times, editors will find that some people in the office fail to print because they do not turn on the printer or accidentally touch the setting key of the printer.
9. Printing paper problem
The paper is jammed. The paper size is inconsistent. After the paper is used up, it can not be printed. Just check the paper.
10. The printer is out
This is easy to understand, because printing requires ink, and printing cannot be done without ink.
11. Computer background shutdown
For example, the print spooler service completes print tasks in the background and interacts with the printer. If the service is turned off, the printer will not be able to print or browse.
A printer is an output device of a computer. John water and Dave Donald co created this printer. It refers to the numbers, letters, symbols and graphics printed on the paper according to the operation results of the computer or the intermediate results in a certain format.
Printing quality, printing speed and noise are the three standards to measure the quality of a printer.
Epson began to study piezoelectric technology more than 20 years ago, and on this basis, it has carried out more than 20 years of development, and finally realized the industrialization of micro piezoelectric printing technology on the printing machine.
