How to solve the bar code printer when the phenomenon of garbled words _ printing equipment problems

takeaway: often use bar code printer friends, should be more or less met, there was a garbled printing this kind of phenomenon, the reason is very complicated, this article is aimed at this kind of phenomenon is discussed, in order to let everyone know the cause and the solution to the statement.

simple discriminant method can put your bar code printer, get another computer to try to see if can be normal printed is garbled, if print is normal, then prove fault and host, or the one on the other computer using normal barcode printer connected to your computer to try it, if the normal fault and your printer. Of course this is only the most simple method of decision problem is, to solve the problem, we must also from software to hardware, one by one, for troubleshooting, suit the remedy to the case.

a, software solutions

1. In the BIOS Settings to change the barcode printer parallel port mode ( If you are using the traditional printing line instead of USB printing line) , enter the BIOS, & quot; 集成的外围; 国家失忆症和平港”模式 , has the following four patterns & quot; SPP' ( The standard parallel port) ,“; EPP' ( Enhanced parallel port) ,“; ECP” ( Extend parallel port) ,“; ECP+EPP' , if your bar code printer model is old, set for SPP mode is recommended, and the current mainstream of bar code printer is recommended set to ECP + EPP mode ( Of course you also can try several patterns are) 。

2。 Stylus printer, printer and paper including ordinary needle printer to print two modes, LQ simulation and himself if the pattern of use is not correct, the phenomenon of print is also likely to be garbled ( In the printer properties can change the print mode) 。

3。 Bar code printer driver installation is also likely to lead to incorrect or damage to the print gibberish, suggest to install the latest printer driver, Can get) on the official site , the driver installation is completed the test page prints out an executable to test the printer is normal.

4。 Used to print the font is not installed or has been damage can occur to print the code, such as font has not been installed or damaged can open & quot; The control panel. The font & quot; , double-click the icon font, in the open window click & quot; File & quot; Menu, choose to install new fonts.

5。 Some decryption software conflict, using pirated software, such as the version of the financial reporting system, tend to cause drive is not normal, lead to print the code, even some genuine software, due to the requirement on the print mouth install encryption dog, often can cause abnormal print.

6。 Virus causes abnormal print, sometimes due to the presence of the virus can also cause printing the code, such as a worm can make computer print a cause garbled, it is recommended to use NORTON etc. The latest version of antivirus software to scan.

7。 System files against damage or loss caused by printing or gibberish, solution: ( 1) From the operating system installation plate extraction or corresponding system files, with the tool of system recovery ( 2) Is to reinstall the operating system.

2, hardware solutions

1. Bar code printer cable fault cause garbled, sometimes print cable a circuit or short circuit and its interface part may lead to print the code. Can be in - MS Under DOS, execute the command & quot; dir> 打印” To detect the barcode printer cable if there is a fault.

2。 Bar code printer itself a hardware failure, can use the printer self-test ( Every brand barcode printers way of self-check each are not identical, please see the barcode printer specification) Judge whether the bar code printer is a hardware failure. If it is really a printer problem, it can only be repaired.

3。 In a print bar code printer is out of memory can occur when the file is too large to print the code, is the best way to extend the bar code printer of memory, but it is also rare, tend to occur in the early days of memory smaller on the printer.

4。 The mainboard parallel port ( Print) Damage resulting in abnormal printing, this kind of circumstance is rare, do not use a parallel port is the best way to print, change a USB cable to print. Of course, if there is no USB printer or host that can only be repairing or replacement motherboard.

5。 The I/O control chip on the motherboard damage, actually this kind of circumstance is not difficult to distinguish, because the motherboard I/O control chip damage often leads to many complications, many input and output devices are affected. To solve only repair the motherboard!

6。 Print mouth near exclusion ( At present almost all motherboard can be seen) Damaged, sometimes resistance change due to external factors, then print the code will light up. Only change new exclusion, failure can be solved.

7。 Using switch box printing may sometimes appear to print the code phenomenon, change the quality guaranteed switch box or don't use a switch box for printing.

the above is the reason why barcode printer garbled words and solution.
