Choosing between wide format printers plotters usually comes down to what you print and what you want to spend. Both of these all-in-one inkjet printers can handle jobs beyond letter-sized paper, yet each one makes a different trade-off. Here is a head-to-head look at the Epson WorkForce Pro WF-7840 and the HP OfficeJet Pro 7740.
Quick Verdict
At a glance, the Epson WF-7840 is the lower-priced pick, while the HP OfficeJet Pro 7740 is the higher-priced all-in-one with a wider stated paper range and a higher mono speed spec. Both cover everyday office tasks like copying, scanning, and faxing. If keeping the upfront cost down matters most, start with the Epson; if you regularly switch paper sizes, the HP's flexibility is worth the extra money.

Product Notes
Epson WorkForce Pro WF-7840 (Certified Refurbished)
The WF-7840 is built around high-volume convenience. It uses DURABrite Ultra pigment ink, offers a 4.3-inch color touchscreen, and supports 48-bit color input for detailed scan and copy work. The rear tray handles 50 sheets, which is useful for the oversized media this wide-format printer is designed for. That combination suits teams that want a single desktop device for scanning, faxing, and wide-format output. The main thing to keep in mind is the condition: this unit is certified refurbished, so it is not a brand-new machine. If you want a wide-format all-in-one that keeps staple office functions in one place and you are comfortable with a refurbished listing, the WF-7840 is a practical choice.
HP OfficeJet Pro 7740 (Open Box)
The OfficeJet Pro 7740 is a flexible all-in-one with a maximum resolution of 4800 x 1200 DPI and 512 MB of memory. Connectivity includes USB 2.0, wireless, and both RJ-11 and RJ-45 Ethernet jacks, which gives offices wired options. For teams that print in color and run mixed-size jobs, this gives one machine to centralize around. The limitation is the condition: this is an open box unit rather than a sealed retail unit. If you need a wide-format workhorse that can connect over Ethernet and handle a variety of paper sizes, the OfficeJet Pro 7740 covers that territory.
Final Choice by Use Case
Pick the Epson WorkForce Pro WF-7840 if your daily routine leans on double-sided wide-format printing and you prefer the certified refurbished route. Pick the HP OfficeJet Pro 7740 if broad paper-size support, wired networking, and solid mono speed matter more, and an open box unit is acceptable. Both models can handle a busy home office or small business; your choice comes down to whether paper flexibility or print speed matters more.
