Dimension comparison
Design and build quality
The HP OfficeJet Pro 9125e Wireless is designed with office environments in mind, focusing on professional output for documents like presentations and brochures. It features a standard printer chassis suitable for desktop placement. The HP Smart Tank Plus 651 Wireless positions itself as a durable solution built to last, emphasizing reliability over time. HP markets the Smart Tank as the only tank printer built to last, suggesting a focus on long-term structural integrity. Both units support wireless connectivity, but the physical design philosophy differs, with the Smart Tank prioritizing the ink tank integration while the OfficeJet focuses on traditional office functionality.
Print speed and performance
Performance metrics are clearly defined for the HP OfficeJet Pro 9125e Wireless. It offers print speeds up to 18 ppm for color documents and 22 ppm for black text. This makes it suitable for offices printing professional-quality color documents where time is a factor. The HP Smart Tank Plus 651 Wireless does not specify exact pages per minute in the provided data. Instead, it emphasizes that it keeps printing well after competitors have quit, focusing on consistency and reliability rather than raw speed numbers. For users who prioritize documented throughput, the OfficeJet provides concrete performance data.
Ink system and operating costs
The most significant difference lies in the ink delivery systems. The HP OfficeJet Pro 9125e Wireless uses a cartridge-based system linked to HP+ Activation. This includes 3 months of Instant Ink, after which a monthly fee applies unless cancelled. This subscription model ensures ink delivery before running out but incurs ongoing costs. In contrast, the HP Smart Tank Plus 651 Wireless features a cartridge-free printing system. It includes up to 2 years of ink in the box, allowing for thousands of pages of printing. The Smart Tank uses a mess-free refill system where users plug ink bottles into the tank, avoiding the squeezing and spilling associated with traditional cartridges.
Connectivity and compatibility
Both printers support wireless printing, ensuring users can stay connected without physical cables. The HP OfficeJet Pro 9125e Wireless specifies the use of reliable dual-band Wi-Fi, which automatically detects and resolves connection issues. This suggests a potentially more robust network performance in crowded signal environments. The HP Smart Tank Plus 651 Wireless lists mobile and wireless printing capabilities, allowing users to print from smartphones and tablets. Both devices support printing from PCs and tablets, ensuring compatibility across standard home and office devices.
Paper handling and features
Paper handling capabilities are more detailed for the HP OfficeJet Pro 9125e Wireless. It includes a 250-sheet input tray, reducing the frequency of refills during large jobs. It also features an auto document feeder and auto 2-sided printing, which enhances productivity for multi-page documents. The OfficeJet also supports faxing, a feature not listed for the Smart Tank. The HP Smart Tank Plus 651 Wireless supports print, copy, and scan functions, plus borderless prints. While it covers the essential multifunction needs, it lacks the specific paper capacity and fax specifications provided for the OfficeJet model.
Software and ecosystem
HP integrates both printers into its software ecosystem via the HP App. This allows users to print, scan, copy, or fax right from their smartphone, PC, or tablet. The OfficeJet Pro 9125e Wireless highlights HP AI features that format web pages and emails with precision, removing unwanted content to prevent wasted pages. The Smart Tank Plus 651 Wireless emphasizes innovation users can trust, powered by HP innovation. Both rely on the same underlying application infrastructure for mobile management, ensuring a consistent user interface for basic tasks regardless of the hardware chosen.
Price and value
The upfront price distinguishes these two models significantly. The HP OfficeJet Pro 9125e Wireless is listed at $219.89, making it the more affordable initial purchase. However, value must be calculated over time. The OfficeJet requires a subscription after the initial 3 months of Instant Ink. The HP Smart Tank Plus 651 Wireless is priced at $329.89, which is higher initially. However, it includes up to 2 years of ink, which represents substantial savings compared to buying cartridges or paying monthly fees. For high-volume users, the Smart Tank offers better long-term value despite the higher sticker price.
Which one should you buy?
Choosing between these printers depends on your volume and feature requirements. If you need fax capabilities, auto document feeding, and a lower upfront cost, the HP OfficeJet Pro 9125e Wireless is the logical choice. It is better suited for traditional office tasks requiring specific formatting and speed. If your priority is minimizing maintenance and ink costs over several years, the HP Smart Tank Plus 651 Wireless is the superior option. Its tank system eliminates the hassle of cartridges and provides years of ink inclusion, making it ideal for home users or small businesses focused on long-term savings.
