Ask the printer problem

Users questions:My printer is Epson LQ-1600, as long as you do not know what the reasons for printing documents, it played a long list to read the English alphabet, not simply play the file I want to play, headache A. Please master Zhijiao are extremely grateful. Fault in the end went wrong?
Experts answer: times I encountered this situation,Possible reasons are as follows: 1 - the driver does not, if the print under DOS or so, it is not a driver problem, testing methods: copy *. txt LPT1: Enter, *. txt file is a text file, so that a meaningful characters string we go to determine fault, note that if DOS does not start under environmental UCDOS, when printed in Chinese is still garbled; 2 - Communications cable problem, need to replace a cable give it a try; 3 - parallel port print parameter settings wrong, CMOS there are three modes in the parallel port, Bi-Directional, ECP, EPP three kinds ofMode, EpsonLQ-1600K can only use the first model, try to correct the work of the parallel port mode; 4 - the printer port burned repair bar. Test whether the burn can be ruled out method, according to the instructions manual, disconnect the printer cable, to start self-test printing to see if normal, if normal,Step 3 is also ruled out in front, then basically you have burned the printer parallel port, while your computer's motherboard does not rule out the possibility of parallel faults, but this easy to test the printer receives another try on the list.
