Choosing between these two HP all-in-one printers comes down to a focused office decision: do you want the lower listed price, or does the 8139e's Wireless designation and longer Instant Ink period better match your priorities? Both models cover print, copy, scan, and fax, so the main distinction is not the basic task list.
Quick verdict
The HP OfficeJet Pro 8135e is the straightforward pick for shoppers centered on the lower listed price and an office-oriented description. The HP OfficeJet Pro 8139e costs more, but its title identifies it as Wireless and includes 1 Full Year Instant Ink. Since both are new HP all-in-one units with the same stated dimensions and core functions, choose based on those named differences rather than expecting a different category of machine.

Where each product wins
HP OfficeJet Pro 8139e wins for the Wireless designation and longer Instant Ink period. Its product title makes both points clear, making it the more fitting choice when those details carry more weight than the price difference.
HP OfficeJet Pro 8135e wins on listed price. The two models are separated by USD 90, and the 8135e description specifically frames it as suitable for small business or office use. That gives it a clear role for a shopper who wants the shared print, copy, scan, and fax functions at the lower figure.
HP OfficeJet Pro 8139e Wireless All-in-One Printer with 1 Full Year Instant Ink
The HP OfficeJet Pro 8139e fits a shopper who specifically wants a Wireless all-in-one printer and prefers the 1 Full Year Instant Ink wording in its title. It also lists print, copy, scan, and fax functions, along with one Ethernet connection and Hi-Speed USB 2.0 device and host connections. Its stated system requirements include macOS 11 Big Sur through macOS 15 Sequoia and Windows 11. Choose this model when the Wireless designation is central to your office setup. The tradeoff is simple: at USD 279.99, it is the higher-priced choice here. Its listed dimensions are 9.170 inches high, 18.120 inches long, and 13.290 inches wide.
HP OfficeJet Pro 8135e All-in-One Printer w/3 Months Instant Ink free w/ HP
The HP OfficeJet Pro 8135e makes the stronger case for a small business or office shopper who wants the lower listed price. Its description highlights color output, 512 MB DDR3 SDRAM memory, and Ethernet and USB connectivity, while its input type covers print, copy, scan, and fax. Those details make it a well-defined all-in-one option without adding a separate printer, scanner, or fax machine to the decision. The limitation is in the title's Instant Ink term: it specifies 3 Months Instant Ink free w/ HP, compared with the 8139e title's 1 Full Year. It shares the same listed 9.170-by-18.120-by-13.290-inch dimensions as the 8139e.
Final choice by use case
Pick the HP OfficeJet Pro 8135e if your priority is the lower listed price and a model described for small business or office use. Pick the HP OfficeJet Pro 8139e if the Wireless designation is the deciding feature and you prefer the longer Instant Ink period named in its title. For shoppers who simply need the shared print, copy, scan, and fax functions, the price-led choice is the 8135e.
