Problem: I bought this printer based on the reputation of HP--not again. I have had it for 5 months and it just stopped working. I went to the web site to get troubleshooting info about the error codes. I have spent an easy 6 hrs working on it and nothing worked. It suggests calling phone support "if you are still having trouble." I called phone support but, because I had bought the printer more than 90 days ago, they wanted [money]per phone call--forget that. I email for support and it sent me a computer generated response redirecting me to the same web page I first started with. I am taking the [money] I would have wasted on the phone call just to get someone to read me the same damn web page and then ask me to phone back later and going to try a new brand of printer. HP no longer means quality!!!
Solution: Negative
