Dot matrix prtrs. followed a different set-up during the old days. 1st, you need to verify is this is LPT1 or COM1, in other words, serial or parallel printer. Then check the printers own setup within its panel to be sure how it is setup. Then, installed to system using the printer model#, etc. to get it to self-test. If you have no manual, then some where depending on the printer, it may have a decal/sticker or embossed on cover instructions for setup. If this is parallel/LPT1 only, just be sure its LPT1 ready. In the bios setup verify that the LPT1 port is enabled and is bi-directional ready plus the cable must be too. The same for serial operation, though a little more complex, just verify because you gave no clue how this is setup. On top of all that, be sure the prthd. rail(s) are clean and then lubed(light oil) so it slides smoothly during printing.
A quick and dirty way for a simple text only output plus it verifies how the printer itself is setup, is the "generic" setup within windoze. Select "generic" instead of KX-P1123 as the model and then finalize it. The output should be very basic 9-pin text. If not then the printer(itself) has condensed or some mode for its default output. That's where you problem lies. However, being such an old printer it could have had a problem and that's why it wasn't used/stored.
FYI -Take my advice use normal text, don't type your message/post in "CAPITALS" it is considered shouting in the forums.
I HAVE AN OLD PRINTER, THE PANASONIC KX-P1123, A 24 PIN, NARROW CARRIAGE DOT MATRIX PRINTER. THE PRINTER LOOKS FINE, SPECIALLY WHEN A SELF-TEST PRINT IS OBTAINED FROM THE PRINTER, BUT IT CAN?T WORK FINE WHEN CONNECTED TO THE P.C., A (NOT TOO) OLD DURON(PENTIUM III COMPATIBLE) ENGINE WITH 256MB RAM. SIMPLY THE FONTS PRINTED LOOK COMPRESED VERTICALLY ONE LINE OR ANOTHER, OR A BLUR PRINT IS OBTAINED WHEN PRINTING IN SIMPLE TEXT-ONLY MODE.
I MUST SAY THAT THE PRINTER HAS BEEN CONNECTED TO THE P.C. USING DEFFERENT VERSIONS OF WINDOWS O.S. AND M.S.OFFICE SUITE TOO, AND THE INTERFACE CABLE IS SHORT ENOUGH TO ASSURE GOOD TRANSMISSION, BUT OFFERING THE SAME DISLAKING RESULTS. I MUST SAY TOO THAT MOST OF THIS SOFTWARE ARE UNHAUTHORIZED COPIES FROM THE ORIGINAL ONES. FINALLY, AN OLD EPSON DOT MATRIX PRINTER HAS BEEN CONNECTED TO THE SAME P.C. AND SAME SOFTWARE, OFFERING A MUCH BETTER PRINTING.
PLEASE HELP ME WITH THIS PROBLEM, OTHERWISE THE PRINTER WILL GO WASTE.
