HP Deskjet printer buying guide

I have a HP Photosmart C4580 scanner/printer/copier, wireless. The printer works wireless and with my computer but I cannot get it to scan an image and send it to the computer. Does anyone know how I can get it to do this?

I know thats a highly stupid question but the instructions do not help what so ever, too confusing! So please just help me. Person who gives the easiest steps gets best answer.

I already bought the Epson model but after I installed it I couldn’t use the wireless printing ;I don’t know where is the problem but the printer didn’t work, I am thinking to return it tomorrow and buy the HP PHOTOSMART C4580, but what about the ink?I already bought Epson because I hear that it’s ink much cheaper than the HP,is that true?

I have a HP Photosmart C4580 Wireless Printer. I am unable to install it wirelessly. I have a wireless N Dlink router. I am able to access all the functions of the printer if it is connected to the laptop through the USB drive. But I am not able to install it wirelessly.
Should I fall back to a Wireless G router? I bought the N router thinking that it would be backward compatible for all such day-2-day requirements.
