The 7720 has a good selection of both wired and wireless printing choices. It includes USB for connecting to a computer and Ethernet for connecting to a wired LAN. (I tested it over an Ethernet connection, with its drivers installed on our test PC running Windows 10 Professional.) It has built-in Wi-Fi, and supports HP wireless direct—HP’s proprietary equivalent of Wi-Fi Direct. It is Apple AirPrint compatible, and supports printing from Google Cloud Print. You can print from, or scan to, a mobile device using the HP Smart app, available for both iOS and Android. While the HP 7740 ships with both PCL and PostScript drivers, the 7720’s sole printer driver is PCL.
The HP OfficeJet Pro 7720 Wide Format All-in-One Printer is designed for small or micro offices in fields such as architecture, graphic design, engineering, or advertising that require printing at up to tabloid size (11-by-17 inches). It is a similar but lower-price alternative to the HP OfficeJet Pro 7740. For the extra money, the 7740 has double the 7720’s paper capacity, split between two trays, and can also scan at up to tabloid size, while the 7720 is limited to scanning legal-size documents. The 7720 is a capable wide-format inkjet all-in-one printer, but be sure to give the HP 7740 a close look, as that Editors’ Choice model’s extra features are well worth the premium you’d pay for them.
The 7720 has a single 250-sheet paper tray that can hold up to tabloid-size paper. This is in contrast to the twin 250-sheet trays found in the HP 7740, which not only gives you twice the capacity but lets you, say, fill one tray with letter- or legal-size paper and the other with tabloid size. The 7720 has a maximum monthly duty cycle of 30,000 pages and a recommended monthly duty cycle of up to 1,500 sheets, which is more than adequate for the printer’s intended use. It includes an auto-duplexer for two-sided printing.
