The HP Deskjet 3520 is relatively small, convenient, wonderful to use and can do everything I need.
The Deskjet 3520 is fast in printing and scanning, paper can print on both sides.
The scanning function and the associated software do I need praise. It automatically displays when scanning the "preview", which can then be edited and saved. Multiple pages can be scanned in order to then jointly save as JPEG with text and numbering. From the scanned PDF pages before saving even individual pages can be deleted. PDF also possible to work with the small resolution of 100 dpi, which does not make any scanning program, but totally sufficient for many applications, and saves disk space.
Under duplex printing is generally understood that a grayscale image with a second color (usually with a spot color) is printed. But I assume that was used in other reviews of the duplex printing in the colloquial sense of Both Sides of a leaf. The HP Deskjet 3520 can print on both sides, regardless of the number of pieces and even with the copy function.
The WLAN connection I have not yet tested. But that seems to work just as easily as the entire installation of the printer, and the drivers and programs on my Win7 laptop.
The operation is very simple and can be done intuitively. It is not a study of the manual required.
The printed image is neat, (I do not print photos - can I therefore do not judge). Paper is fed accurately to the last sheet. Even when printing on both sides of a sheet of the paper guide is properly.
I would not complain about the ink used me. The 364XL black cartridge fits easily. With refill and compatible cartridges I have already made very bad experiences in various of my printer. I use only original ink, the bottom line is still the best solution for me, both the anger and the time spent, as well as the costs. It is in the area is just too much junk on the market on the way.
The device uses a little louder than I was used to from my Epson that, not least due to its weight makes a solid impression.
The HP Deskjet 3520 convinced absolutely to the price-performance ratio.
For my personal use of the HP Deskjet 3520 is more than adequate.
