I have 2 of the HP Photo Smart Premium E Printer, and love it.
The 7510 is a slight improvement over the perfect ones I already have.
A bit sleeker, scans to your computer easily, copies, eprints (directly or remotely), and now faxes wirelessly! I can print my photos (holds photo paper and copy paper at the same time) while I am on vacation directly to my home computer to print out while I am away!
I ordered this printer for my daughter for school, as she is now on the west coast. She was able to set it up within a few minutes after opening the box (she is not good in the technology area). She scanned, printed, and surprisingly, found out she could fax, without using a phone line! She only has a cell phone, therefore no actual phone jack to plug in for a fax. But with the efax, she sent a fax wirelessly, using the internet, and within a few minutes, received a response to her fax from the company she was dealing with!
I have recommended HP printers to several of my co-workers, who have since purchased HP, and are thrilled.
