1. Turn on the printer again.
Turn off the printer power, wait a moment, and then turn on the barcode printer, which not only clears the printer memory, but also solves many printing faults.
2. Check whether the printer is online, otherwise it cannot be printed.
3. Set the printer as the default printer.
4. Cancel the suspension of printing.
5. Make the free space on the hard disk not less than 50MB.
If the available hard disk space is less than 10MB, you must free more space to complete the printing task.
6. Please check whether the print port setting is normal, and make sure that the printer has been set to the appropriate port. The most commonly used port settings are LPT 1 and USB port.
7. Whether the printer driver is installed correctly.
Sometimes the driver of the barcode printer may be damaged or the wrong driver may be installed, which may also lead to incorrect printing. Treatment method:
(1) Delete icons that cannot be printed.
(2) Install the user manual and reinstall the relevant printer driver.
8. Check whether the printer is connected properly.
(1) Whether the print line is plugged in tightly, and ensure that both ends of the cable connecting the computer and the barcode printer are plugged in. If you use a print switching device, bypass the switching device, connect the printer directly to the computer, and then try to print.
(2) Test port connection Connect the barcode printer to another available port and try to print the document again. If it can be printed, the original port is damaged.
(3) Test the barcode printer cable and replace it with another printer cable, and then try to print the document again. If it can be printed, it means that the original line is damaged.
If the above problems can't be solved in time, then users have to contact the purchase service provider in time to provide professional technology for inspection and handling.
