Choosing between these two all-in-one printers scanners comes down to a focused tradeoff: the HP OfficeJet Pro 8139e carries a 1 Full Year Instant Ink phrase in its title, while the HP OfficeJet Pro 8135e is listed at the lower price and names 3 Months Instant Ink free w/ HP. Their core functions and listed physical dimensions are otherwise closely aligned, so the decision is less about print-versus-scan capability and more about which package wording and price fit your office setup.
Quick verdict
Pick the HP OfficeJet Pro 8139e Wireless All-in-One Printer with 1 Full Year Instant Ink when the longer Instant Ink term named in the title is your main priority. Pick the HP OfficeJet Pro 8135e All-in-One Printer w/3 Months Instant Ink free w/ HP when the lower listed price matters more and you still want print, copy, scan, and fax functions. The listed-price spread is $35.90.

Where each printer wins
Choose the HP OfficeJet Pro 8139e for the longer Instant Ink term in its title
The 8139e is the clearer fit for a shopper who wants the title to include 1 Full Year Instant Ink. It is also explicitly described as a Wireless All-in-One Printer in its title, alongside the same print, copy, scan, and fax capability listed for the 8135e. Its Ethernet and Hi-Speed USB 2.0 connections provide the same stated wired connection types as the other model.
Choose the HP OfficeJet Pro 8135e for the lower listed price
The 8135e is the pick for keeping the upfront listed price lower while retaining the same stated all-in-one functions, 512 MB DDR3 SDRAM memory, and dimensions. Its title includes 3 Months Instant Ink free w/ HP, making it the better match when that shorter named term is sufficient for your intended use.
Product notes
HP OfficeJet Pro 8139e Wireless All-in-One Printer with 1 Full Year Instant Ink
Choose the 8139e when the phrase 1 Full Year Instant Ink is the deciding feature for your household or office. Beyond that title distinction, it is positioned for business use and handles color printing, copying, scanning, and faxing. The listed Ethernet and Hi-Speed USB 2.0 connections can suit a desk setup that uses wired networking or USB connections. Its compact listed measurements of 18.120 inches long, 13.290 inches wide, and 9.170 inches high match the 8135e, so size does not create a meaningful separation here. The tradeoff is its USD 225.89 listed price, which sits at the upper end of this two-printer comparison.
HP OfficeJet Pro 8135e All-in-One Printer w/3 Months Instant Ink free w/ HP
The 8135e makes sense for a small business or office that wants the lower USD 189.99 listed price without giving up the core functions shared by both models: color printing, copying, scanning, and faxing. It also lists 512 MB DDR3 SDRAM memory plus Ethernet and Hi-Speed USB 2.0 connections. Since its dimensions match the 8139e, it can be chosen on package wording and price rather than physical footprint. Its limitation is the shorter 3 Months Instant Ink free w/ HP wording in the title compared with the 8139e's 1 Full Year Instant Ink phrase. Select it when that tradeoff better matches your priorities.
Final choice by use case
Choose the HP OfficeJet Pro 8139e if the longer Instant Ink term in its title is worth placing ahead of the listed-price difference. Choose the HP OfficeJet Pro 8135e if you want the lower-priced route to the same listed all-in-one functions, matching dimensions, and matching Ethernet and Hi-Speed USB 2.0 connection types. For most shoppers, that makes the Instant Ink wording the practical tiebreaker.
