HP Deskjet printer buying guide

Hey guys, I just printed out a document, but the text is really sharp at the left and right edges, but kind of blurry (though still readable) in the middle, so I want to calibrate my printer, though I can’t figure out how, I can’t find it at Solution Center… Can anyone help me please?

And can anyone tell me which printer they feel is superior over the other. Or, are they about the same? Appreciate your opinion. Also, what would you consider a decent price to pay for the 2575? Thank You

every time i turn on the printer and try to print an error message comes on the printer pannel: Ink Cartridge Problem
Remove and Check Ink Cartridge on right.
Refer to printer documentation.
i have cleaned the contacts and reseted the printer checked hp website for a solution, taken out the cartridge and put it back in but nothing works.
and i cant print.
anyone knows a solution ?

the hp photosmart 2575 all in one printer has wireless printing but i’m not too sure how to set it up any help will be great thanx

I need to know how to get my scanner to scan 4-6 pictures at one time and not have them on one whole page when you look at them. I want mine to scan them but put them in separately. I know it can be done and I tried doing so like my help option said but it does not do it. Can anyone help?????? I have alot of pictures to scan and I will be doing it forever if I can’t change it.
