HP printers - beware

I bought a dudd HP printer. Gave problems from the beginning. The computer shop took it in several times while still under guarantee. But, it kept on frustrating me. Every second time you want to print, you need to run print doctor. Scan blank pages too. Stripes over the pages. As soon as you are out of warranty, you are on your own - sorry for you. We can do nothing for you. Stay away from this brand. It is only frustrating. I would give it less than one star. Very very poor.
