The **HP DeskJet 3755** is a compact, wireless all-in-one printer that can print, copy, and scan. It features HP Thermal Inkjet technology, supports wireless connectivity (Wi-Fi 802.11b/g/n), and is Instant Ink ready, which can save up to 50% on ink costs[1]. It prints up to 8 pages per minute (ppm) in black (ISO) and 5.5 ppm in color. The printer uses two cartridges: one black and one tri-color, with standard cartridges yielding around 100–120 pages and high-yield XL cartridges producing about 300 pages each[1].

The printer handles various media types including letter paper (16–32 lb), envelopes (20–24 lb), cardstock up to 110 lbs, and photo paper up to 4 x 6 inches and 145 lbs weight, making it versatile for different printing needs[3].

Setup is straightforward: after unpacking, you connect the power cable, turn on the printer, install ink cartridges, load paper, and download drivers or the HP Smart app for mobile printing support[2].

Some user reviews note that while scanning works, it may not be ideal for heavy scanning needs, as the scanner can struggle with multi-page document feeds[4].
