Download the latest, greatest driver for your printer from Lexmark's website. Go into control panel, then Add/Remove Programs, and uninstall anything related to Lexmark. Unplug the printer and reboot the computer. Once the computer is back up run the driver software and follow the instructions. Don't plug the printer back in until instructed to do so.

Keep in mind the scanner on most(all?) All-in-one (AIO) is only 300 dpi, not the best for pictures. The printer has much higher resolution, I'm sure (Haven't looked). I have had two Lexmark AIO units. My latest has a flat bed scanner, copies, prints, faxes, guess that's a 4-in-one. I have had good experience with Lexmark and their ink cartridges are easy to refill, saves $$ if you're into that stuff. Not all printers are equal, we also have an Epsom and it is very difficult to re-ink.

check with the software that comes with the printer. some bundled software nowadays may have extra features to help users.

OK Sapphires you have answered my questions. Now I will suggest something absolutely stupid. I suspect your printer is one of many models Lexmark built that has a peculiarity. Next time you print a photo remove your internet connection cable and the job will/should complete. There, I told you the cure was stupid. Lexmark built about 50 or more different models with this defect. Then they made it difficult to find the answer on their web site. The article will not be there now probably as these are older printers now. I could not find your model on their site, nor mine. Ours did the same trick and it was always when printing photos and always around 45 to 50% finished when the printer stalled. All that expensive ink wasted does not make for a happy customer.
