+ 0 Votes Serial or Parallel? robo_dev September 16, 2013 at 9:20am PST Are you using a convertor like from USB to serial or parallel? + 0 Votes Not being familiar with this brand of printer, wizard57m-cnet Moderator September 14, 2013 at 5:15am PST can't really say for sure, but it sounds as if either a setup problem in the printer itself or possibly a faulty port/cable. As in a pin assignment somewhere is switched. If you have the user manual, it should give instructions for accessing the printer setup, and if you have another cable you could try that.
