Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
What ink cartridges have you been using, please?
How old is the printer in question?
Have you tried an Alignment operation on it? and if so, was it successful?
If you need instructions, let me know, please.
Then I'm sorry to say, it may be the end of the line for the printer. It does have all the symptoms of a severe problem with the inking system... except for perhaps one spot of hope:
1. what program are you printing from?
2. what does the poor quality printing look like, please? a brief description, or perhaps a scanned image of a typical printed page, would do.
