If your printer is causing problems for you in terms of printing streaks of ink on paper instead of clearly defined pictures and words, then you may need to remove the printer's cartridge and replace, clean or repair it. Often, this is an easy printer repair to fix.
When your printer provides you with a message that it is not able to communicate with your computer, this could be an indication of a loose cable or a missing communication link. You will want to restart the computer for the printer repair and check all cables in the process.
