Choosing between two all-in-one printers scanners is often less about basic tasks and more about the terms around them. Both HP choices are set up to print, copy, scan, and fax, but they differ in listed price, condition, stated size information, and Instant Ink duration. The listed-price spread is $100.90, so deciding which details matter most before purchasing can make the choice clearer.
Quick verdict
The HP OfficeJet Pro 9125e gives shoppers a stated black print-speed figure, while the HP OfficeJet Pro 8139e provides full listed dimensions. Their shared Ethernet and Hi-Speed USB 2.0 device connectivity means that connection type is not the deciding distinction here. Focus instead on the listed price, the Instant Ink terms, and whether the product condition fits your purchase.

Where each printer wins
HP OfficeJet Pro 9125e: The stated 22 ppm black print speed gives this model a specific figure for shoppers whose regular document printing centers on black text. That figure can be more useful than a general all-in-one description when speed is part of the decision.
HP OfficeJet Pro 8139e: This model is the more defined choice when desk or shelf planning depends on exact measurements. Its listed 18.120 x 9.170 x 13.290-inch dimensions give a complete size reference, rather than only a height measurement.
Product notes
HP OfficeJet Pro 9125e All-in-One Printer
At USD 124.99, the HP OfficeJet Pro 9125e All-in-One Printer is the lower-priced entry in this comparison. Its stated three months of free Instant Ink is a concrete reason to choose it, and the description also lists 512MB of memory for office-oriented work. For shoppers who want the smaller of the two listed prices, that combination makes a straightforward case. The key limitation is its Used condition, making it a different proposition from a New-condition purchase. Select the 9125e when that condition suits the purchase and the shorter Instant Ink period fits your needs.
HP OfficeJet Pro 8139e Wireless All-in-One Printer with 1 Full Year Instant Ink
At USD 225.89, the HP OfficeJet Pro 8139e Wireless All-in-One Printer with 1 Full Year Instant Ink is priced above the 9125e. Its New condition and the 1 Full Year Instant Ink wording in the title are the central reasons to choose it. The printer is also described with 512 MB DDR3 SDRAM memory, adding a specific hardware detail for comparison. Its limitation is the higher listed price, so it asks for a larger upfront spend. Choose the 8139e when New condition and the longer Instant Ink term outweigh that price difference.
Final choice by use case
Pick the HP OfficeJet Pro 9125e when a Used-condition printer fits the purchase and you want an all-in-one for print, copy, scan, and fax at the lower listed price. Pick the HP OfficeJet Pro 8139e when New condition is the priority for those same core tasks and its listed configuration better matches what you want.
