HP OfficeJet Pro 9720e: Setup, Drivers, Ink and Common Problems

Is the HP OfficeJet Pro 9720e right for you?

The OfficeJet Pro 9720e is HP's 2023 wide-format all-in-one and the successor to the long-running 7720, printing up to 11 x 17 or A3 while scanning at letter size. It moved to the HP 924 cartridge family and to HP+, so it needs Original HP ink and an internet connection after activation. Teachers, small design studios and churches are its natural buyers, and they should budget for the larger EvoMore cartridges if they print posters regularly.

Best for: Small studios and classrooms printing A3 on an HP+ machine

Setting up the HP OfficeJet Pro 9720e

Set up in HP Smart with an HP account; Ethernet and dual-band Wi-Fi are available. Select the 11 x 17 or A3 size in the driver when you load large sheets, extend the tray and output support, and keep the rear clear for the duplexer. The ADF and flatbed remain letter-sized, so large originals must be scanned in sections.

1. Unbox and prepare. Remove every piece of shipping tape and packing material, install the ink cartridges, and load paper in the tray.
2. Join your Wi-Fi. Keep the printer close to the router for setup. Most printers only connect to the 2.4GHz band, so if your router broadcasts one merged network name you may need to split the bands temporarily. See our Wi-Fi guide if it will not join.
3. Install the setup app. Use HP's official app rather than a driver you found on a search result — third-party driver sites are the most common source of printer malware.
4. Add the printer. On Windows 11: Settings › Bluetooth & devices › Printers & scanners › Add device. On macOS: System Settings › Printers & Scanners › Add Printer.
5. Print a test page and run a scan if this is an all-in-one, so you find any problem now rather than when you are in a hurry.

Ink, toner and supplies

The HP OfficeJet Pro 9720e uses the following consumables. Match the number exactly when you buy: the same printer family often uses several different cartridge numbers by region.

• HP 924 Black
• HP 924 Cyan
• HP 924 Magenta
• HP 924 Yellow
• HP 924e EvoMore high-yield
• HP 925 (UK/EU)

High-yield (XL) versions almost always cost less per page if you print regularly. On third-party ink and toner, read our honest assessment first, and note that some manufacturers push firmware that rejects non-original chips.
