Among the standard security features for a midrange AIO like this, you also get HP's Jet Advantage Private Print (a feature known as "Secure Print" on some laser printers), which allows you to secure sensitive print jobs with a PIN. Scanning to and printing from USB thumb drives is supported via a port located on the left-front side of the chassis. The scanner can save to BMP, JPEG, PNG, RTF, TIF, TXT, and image and searchable PDF.
Other mobile connectivity options include: AirPrint, Mopria, and HP's own ePrint.
FREE SCANNER SOFTWARE FOR HP 6978 PC
The OfficeJet 6978's connectivity options consist of Wi-Fi, Ethernet, connecting to a single PC via USB, and Wireless Direct, HP's equivalent to Wi-Fi Direct for making peer-to-peer connections with mobile devices sans a network or router. The OfficeJet 6978's maximum monthly duty cycle is 20,000 pages, with a suggested monthly volume of 200 to 800 pages, compared to the MB2720's 20,000 pages maximum and 1,250 pages recommended, and the MFC-J985DW's maximum duty cycle of 2,500 pages and up to 1,000 pages recommended. But, as mentioned, the OfficeJet model is the only one that supports unassisted two-sided scanning, a feature that can be handy in many small-office settings. With its 35-sheet capacity, the OfficeJet 6978's ADF is larger than the MFC-J985DW's 20 sheets and smaller than the MB2720's 50 sheets. All three of these AIOs have ADFs for feeding documents to the scanner. The OfficeJet 6978's paper capacity consists of one 225-sheet cassette, compared with the MB2720's 500 sheets split between two 250-sheet drawers, and the MFC-J985DW comes with just one 100-sheet paper tray.
