My name is ***** ***** I would like to answer your question regarding your printer problems. You have a true work horse of a printer the Panasonic XP1124. However with age, you have started seeing the physical stresses of years of printing. Pieces falling into the print area has caused print quality and mechanical issues.
You have several choices to address your printer proiblem.
1. Have the printer serviced. This could be costly with parts and labour costs. You could be looking at $200+ in repair costs depending on the extent of the damage.
2. Check eBay. There are a couple of listings for your printer at the moment. For roughly $100, you can get a re-furbished XP1124. All you would need to do then is to unplug your printer, and plug in the new one. No changes required for drivers.
3. Purchase a new dot-matrix printer. I performed a quick search on Google for new dot-matrix printers, and there are Dot-Matrix printers still available from printer vendors such as Epson, Fujitsu, OKI, Lexmark etc. The newer printers start in the $400-500 range. The newer printer would require you to install new drivers, but those are usually included on a CD/DVD disk that comes with the printer.
So, the choice is up to you. I hope I was able to give you enough information to make an informed decision.
