HP Deskjet printer buying guide

or any printer preferably a hewlett packard

I have a problem with my scanner/printer, HP PhotoSmart 2575 All-in-one. Each time I scan an object, there is a thick black line (2 centimeters thick) running from top to bottom. There is no difference whether it is a document or photo. Even if I transfer it directly to the computer or USB disk, it still has this black line. But if I print a document from the computer, it is fine. It is only the scanner that has this problem. It was always perfect right up till yesterday. Is there anything I can do, without paying out a fortune for repairs.
Thanks in advance to all who answer to this message.

using a hp deskjet 930c printing. why are there lines in the photos?

i have a hp photosmart all-in-one printer.
it says that it has a paper jam, but there is definatly no paper in it.
are there any switches that it could have hit or something?
i don’t want to take it in.
it is a waste of time and maybe money.
am i just missing something?

i have to put my computer on to print on photo paper?
i have an hp photosmart printer, hp glossy photo paper and im using microsoft word. do i just hit print or do i have to put it on a special setting??
