This article focuses on the various hard and soft faults of printing garbled characters. The purpose is to improve the ability of everyone to solve the problem of printing garbled characters, so that everyone can no longer do nothing in the face of printing garbled! Simple identification method can put your barcode printer Try it on another computer that can print normally. If it prints normally, it proves that the fault is related to the host, or try to connect a normal printer on another computer to your computer. If it is normal, the fault is related to your printer. But at least two computers or two printers are not available to the average home user.
Of course, if you don't have the above conditions, it doesn't matter. Let's take a look at the garbled ones one by one.
Software solution
1. Change the printer parallel port mode in the BIOS settings (if you are using a traditional print line instead of a USB print line), enter the BIOS, "Integrated peripheral→parallel port mode", there are the following four modes "SPP" (standard Parallel port), "EPP" (enhanced parallel port), "ECP" (extended parallel port), "ECP+EPP", if your printer model is older, it is recommended to set it to SPP mode, while current mainstream printers recommend Set to ECP+EPP mode (of course you can try it in several modes).
2. The dot matrix printer, including the ordinary needle printer and the ticket printer, has two modes of LQ emulation and self-printing. If the mode used is incorrect, printing may also be garbled (the print mode can be changed in the printer properties) .
3. Improper or damaged printer driver installation may also cause garbled printing. It is recommended to reinstall the latest printer driver (available on the official website). After the driver is installed, you can print a test page to test whether the printer is normal.
4. If the font used for printing is not installed or damaged, garbled characters may also appear. If the font is not installed or damaged, open "Control Panel → Fonts", double-click the font icon, and click the "File" menu in the window that opens. , choose to install a new font.
5. Software conflicts, using pirated software, such as some decrypted version of the financial reporting system, often cause the driver to be abnormal, resulting in garbled printing, even if some genuine software, because the installation of the dongle on the print port, often leads to Printing is abnormal.
6. The virus causes printing abnormalities, and sometimes the garbled printing may occur due to the presence of viruses. For example, if a worm causes the computer to print garbled for no reason, it is recommended to use the latest version of anti-virus software such as Norton for killing.
7. The system file is damaged or lost, causing abnormal printing or garbled. The solution is to extract from the operating system installation disk or use the system's own tools to restore the corresponding system files. The second is to reinstall the operating system.
Hardware solution
1. Printer cable failure causes garbled printing, and sometimes the open or short circuit of the printed cable and its interface may cause garbled printing. You can run the command "dir>prn" under MS-DOS to check if the printer cable is faulty.
2. The printer's own hardware failure, you can use the printer self-test (the self-test methods of the printers of different brands are different, please refer to the printer manual) to determine whether the printer has a hardware failure. If it is really a problem with the printer, it can only be repaired.
3. The printer has insufficient memory. When the printed file is too large, the garbled printing may occur. The best way is to expand the printer's memory. However, this situation is rare. It occurs mostly on printers with small memory. .
4. The motherboard parallel port (printing port) is damaged and the printing is abnormal. This kind of situation is rare. The best way is not to print with the parallel port and replace it with a USB cable. Of course, if there is no USB port on the printer or the host, you can only repair or replace the motherboard.
5. The I/O control chip on the motherboard is damaged. In fact, this situation is not difficult to distinguish. Because the I/O control chip on the motherboard is damaged, it often brings many complications, and many input and output devices will be affected. To solve the problem, you can only repair the motherboard!
6. The exclusion of the discharge near the print port (which can be seen on almost all current motherboards) is damaged. Sometimes the resistance value changes due to external factors, and garbled characters may appear. The fault can be solved simply by replacing the new displacement.
7. Printing with the switch box may also cause garbled printing. Replace the switch box with the guaranteed quality or do not use the switch box for printing.
