HP C2WM0A#B1H Review: 500-Sheet Capacity with Mandatory HP Ink
The HP OfficeJet Pro 9135 is a capable all-in-one inkjet for small offices, offering fast color printing, robust security, and a high paper capacity, but it requires an ongoing subscription for optimal ink management and locks out third-party cartridges.

The HP C2WM0A#B1H, marketed as the HP OfficeJet Pro 9135 Wireless All-in-One Color Inkjet Printer, is a multifunction device designed to serve as the central print hub for a small to medium business or a busy home office. It consolidates printing, scanning, copying, and faxing into a single unit, promising professional-quality color output, high-volume paper handling, and modern features like AI-assisted formatting and network security. This review analyzes its specifications, design, and user feedback to determine if its blend of productivity and proprietary ecosystem is the right fit for your workspace.
Positioned as a “Best-for-Office” solution, this printer targets users who need reliable, fast color documents for presentations, brochures, and everyday office tasks. It stands out with a substantial 500-sheet input capacity, single-pass duplex scanning, and HP’s Wolf Pro Security suite. However, its operation is tied to original HP ink cartridges and an optional Instant Ink subscription service, which is a significant consideration for long-term cost of ownership. For teams seeking a versatile, secure all-in-one with strong wireless connectivity, the HP OfficeJet Pro 9135 presents a compelling, if somewhat locked-in, package.

Design and Build
The HP OfficeJet Pro 9135 has a substantial office footprint, measuring 15.6 inches deep by 17.2 inches wide by 12.53 inches high and weighing 26.1 pounds. This size accommodates its dual 250-sheet input trays and internal automatic document feeder (ADF), making it suited for a dedicated printer station rather than a cramped desk corner. The build incorporates sustainable materials, with HP stating it uses more than 40 percent recycled plastic content.
The front panel is dominated by the 4.3-inch color touchscreen, which HP describes as having a phone-like user interface for intuitive navigation. Physical controls are minimal, relying on this touchscreen for most functions. A front-facing USB port is present for direct printing from flash drives. The design prioritizes function for office workflows, with an easy slide-off scanner glass and an ADF capable of handling single-pass, two-sided scanning to save time on multi-page documents.
Performance and Features
Print, Scan, and Copy Speeds
According to manufacturer data, the HP C2WM0A#B1H offers print speeds up to 25 pages per minute (ppm) for black and white and up to 20 ppm for color. The maximum copy speed for black and white is listed as 23 ppm. For scanning, the inclusion of a single-pass duplex automatic document feeder is a significant productivity feature, allowing both sides of a document to be scanned in one pass. The maximum copy resolution is up to 600 dpi for both color and black and white. Owner reviews note the printer performs quickly, with one user reporting a scan and print of two pages taking approximately 16 seconds.
Connectivity and Ports
Wireless connectivity is a core feature, utilizing what HP calls its “most reliable dual-band Wi-Fi,” which is designed to automatically detect and resolve connection issues. This facilitates printing from laptops, PCs, and smartphones. A front USB flash drive port allows for direct printing and scanning without a network connection. The printer is compatible with the HP Smart App, enabling users to print, scan, copy, or fax directly from a smartphone. Fax functionality is built-in, rounding out its all-in-one capabilities.
Key Features and Software
Several software-driven features define the user experience. HP AI is promoted to optimize print formatting from web pages and emails, aiming to remove unwanted content and avoid wasted pages or awkward layouts. For security, HP Wolf Pro Security is included to help protect the device and network from cyber threats through bolstered security measures and periodic firmware updates. The printer is also part of HP’s Instant Ink ecosystem, which includes a three-month trial. This subscription service monitors ink levels and delivers replacement cartridges before you run out.
Setup, Support and Ownership
Setup experiences from owners vary. While some found the process easy, others reported it was not as straightforward as prior HP models and required assistance. The printer comes with a one-year limited hardware warranty. Long-term ownership is heavily influenced by HP’s ink policy. The manufacturer specifies that this printer is intended to work only with cartridges with original HP chips or circuitry and will block cartridges using non-HP chips. Firmware updates will maintain this restriction. The included three-month Instant Ink trial transitions to a paid monthly subscription unless cancelled, which some users noted adds an ongoing cost. Compatible cartridges include the HP 936 series and the planned HP 936e EvoMore series.
What Owners Say
Overall owner sentiment is positive, reflected in its rating. The majority of reviews are favorable, with high praise for print quality, speed, and the ease of use once set up. Users appreciate the fast printing and copying speeds, the quality of color documents, and the functionality of the automatic document feeder. However, feedback highlights two consistent points of contention. First, the setup process can be challenging for some, contrasting with the plug-and-play experience of older models. Second, the integration with HP’s Instant Ink service and the requirement to use only original HP cartridges receive mixed reactions; some see the convenience and potential ink savings, while others are wary of the subscription model and the lock-in that prevents using third-party ink alternatives.

Who Should Buy It (and Who Should Skip It)
The HP C2WM0A#B1H is an excellent fit for small business teams or home offices that regularly produce professional color documents and value workflow efficiency. Its high paper capacity, automatic duplexing, and fast speeds make it ideal for environments with moderate to high print volumes. The built-in security features are a significant plus for any office concerned with network protection. It’s also a good match for users who prefer the convenience of a managed ink service like Instant Ink to avoid unexpected downtime.
This printer is not the best choice for users on a very tight budget who rely on third-party or refilled ink cartridges to control costs, as the hardware actively blocks them. Individuals with extremely limited desk space may also find its footprint too large. Those who want a completely subscription-free experience or who had negative experiences with HP software setup in the past might want to consider alternatives.

Final Verdict
The HP OfficeJet Pro 9135 is a capable and feature-rich all-in-one printer that successfully meets many core office demands. Its performance in producing fast, quality color prints, coupled with the time-saving automatic document feeder and strong security posture, makes it a productive partner for a small team. The substantial paper capacity means fewer interruptions, and the modern touchscreen interface is generally well-received. When evaluated purely on its hardware and feature set, it represents a solid investment in office productivity.
The primary caveat, and a decisive one for many buyers, is HP’s controlled ecosystem. The mandatory use of original HP ink and the push toward the Instant Ink subscription model represent a long-term commitment to HP’s supply chain. For those comfortable with this model, the printer delivers convenience and reliable output. For those who prioritize flexibility and lower consumable costs, this lock-in is a major drawback. It’s a powerful tool, but one that comes with specific terms of use. For reviews of other productivity-focused devices, check out our Reviews hub.
