HP Envy 6155e Wireless All-in-One Color Inkjet Printer, Portobello, Print, scan, copy, Duplex printing Best-for-home, 3 month Instant Ink trial included, AI-enabled (714L5A) vs Nelko Label Maker Machine with Tape, P21 Bluetooth Label Printer, Wireless Mini Label Makers with Multiple Templates for School Office Home, White

Print Functionality & Use Cases

The HP Envy 6155e is designed for full home office or family use, handling color printing, scanning, and copying with duplex printing. It supports everyday documents, homework, and borderless photos. In contrast, the Nelko P21 is a specialized label maker focused solely on creating adhesive labels using thermal printing technology. While the HP printer serves as a central hub for general document output, the Nelko P21 excels in niche tasks like organizing school supplies, office files, or household items with custom-printed labels.

The HP Envy 6155e offers print speeds up to 7 ppm for color and 10 ppm for black, suitable for moderate home use. The Nelko P21 uses BPA-Free Direct Thermal Technology with 203 DPI resolution, delivering high-definition monochrome prints without ink or toner. This difference reflects their core purposes: one is a multifunction printer for diverse content, the other a compact tool for precise labeling. The HP’s ability to handle multiple paper types and sizes contrasts sharply with the Nelko’s fixed label dimensions (14×40mm, 14×50mm, 14×75mm, etc.), which are pre-determined and non-adjustable.

Connectivity & Wireless Features

Both devices support wireless connectivity, but they differ significantly in scope and compatibility. The HP Envy 6155e features dual-band Wi-Fi with automatic connection detection and issue resolution, enabling seamless printing from smartphones, tablets, and PCs via the HP App. This ensures broad device compatibility across platforms and reliable performance in typical home networks. The Nelko P21 connects via Bluetooth to iOS and Android phones through its dedicated app, offering portability and on-the-go access—but it does not work with computers and has known incompatibility with Android 14 devices.

The HP’s Wi-Fi integration allows for broader network flexibility and remote printing capabilities, while the Nelko’s Bluetooth-only setup limits its use to mobile devices and requires an active app connection. The HP’s system also includes security updates and firmware improvements, ensuring long-term reliability. The Nelko P21’s reliance on a single app interface means users must maintain app updates—specifically version V4.8.0 for iOS—to ensure optimal function. This makes the HP more versatile for multi-device households, while the Nelko remains ideal for users who prioritize mobility over cross-platform access.

Design & Portability

The HP Envy 6155e is built for desktop placement with a 100-sheet input tray and a 2.4-inch color touchscreen, emphasizing usability and stability. Its design prioritizes functionality over size, making it best suited for a permanent spot in a home office or study area. The printer is constructed with at least 60% recycled plastic, reflecting HP’s sustainability focus. In contrast, the Nelko P21 is engineered for extreme portability—half the weight and size of traditional label makers—allowing it to fit easily in a pocket or bag.

This compact form factor enables spontaneous labeling anytime, anywhere, which suits users needing quick organization solutions on the move. However, the HP Envy 6155e’s larger footprint supports higher-volume tasks and better paper handling, while the Nelko P21’s small size comes with trade-offs: no computer compatibility and limited label length options. The HP’s intuitive touchscreen enhances user experience during complex tasks, whereas the Nelko relies entirely on smartphone interaction via its app. The choice hinges on whether you need a stationary, feature-rich machine or a lightweight, on-demand labeling tool.

Price & Value Comparison

The HP Envy 6155e is priced at $79.89, while the Nelko P21 costs $23.26—a difference of $56.63, making the label maker about 71% cheaper. This significant price gap reflects their distinct roles: the HP is a full-featured all-in-one printer with advanced AI, wireless security, and a 3-month Instant Ink trial included, while the Nelko is a specialized, low-cost tool for label creation. The HP’s value lies in its versatility, supporting printing, scanning, copying, and auto-duplexing, whereas the Nelko delivers minimal functionality at a fraction of the cost.

Despite the lower upfront price, the Nelko’s value proposition is narrow—focused only on labeling. The HP’s inclusion of a 3-month Instant Ink subscription adds immediate utility, though future monthly fees apply after that period unless canceled. For users seeking a single solution for document management, the HP offers greater long-term value per dollar spent on functionality. The Nelko’s affordability shines only if your sole need is labeling; otherwise, the HP provides far more bang for the buck across multiple daily tasks.

Ease of Use & User Experience

The HP Envy 6155e features a smooth, intuitive 2.4-inch color touchscreen that simplifies navigation through print jobs, settings, and scan functions. Its AI-enabled technology automatically formats web pages and emails to eliminate wasted pages and awkward layouts, enhancing workflow efficiency. The HP App further streamlines printing, scanning, and copying from any mobile device. In contrast, the Nelko P21 relies entirely on a smartphone app for operation, requiring users to download the “Nelko” app, install the tape roll, connect via Bluetooth, and select templates—all steps that must be repeated for each print job.

While the HP’s interface is self-contained and accessible without external devices, the Nelko demands constant phone involvement. The app includes 3600+ icons, 700+ borders, 5500+ materials, and 750+ templates, offering rich customization—but this complexity can overwhelm casual users. The HP’s standalone controls make it easier for family members of varying tech skill levels to operate independently. The Nelko’s reliance on app-based workflows limits accessibility for those without smartphones or who prefer physical interfaces.

Sustainability & Environmental Impact

The HP Envy 6155e emphasizes environmental responsibility by incorporating at least 60% recycled plastic in its construction. Additionally, HP promotes forest conservation through its “HP Protects Forests” initiative, where every page printed contributes to forest protection, restoration, and management. This commitment extends beyond materials to include responsible ink delivery via the Instant Ink program, which reduces waste by delivering ink before depletion.

The Nelko P21 does not mention environmental materials or sustainability initiatives in its provided data. Its thermal printing method eliminates ink and toner cartridges, reducing some waste, but it lacks transparency around material sourcing or ecological programs. While the absence of consumables like ink may seem eco-friendly, the lack of stated sustainability goals means users cannot assess its environmental footprint. The HP’s holistic approach to green design gives it a clear edge for environmentally conscious buyers.

Which should you buy?

Choose the HP Envy 6155e if you need a versatile, all-in-one printer capable of handling color documents, photos, scans, and copies with duplex printing, AI-enhanced formatting, and reliable wireless connectivity. At $79.89, it offers comprehensive functionality ideal for home offices or families managing schoolwork, personal projects, and photo printing. Its 3-month Instant Ink trial adds immediate value, and its sustainable design aligns with eco-conscious values. The Nelko P21, priced at $23.26, is best for users who require only a portable, Bluetooth-connected label maker for organizing school supplies, office files, or household items. If your primary need is labeling, the Nelko’s compact size and low cost make it a smart pick—but for any broader printing task, the HP Envy 6155e delivers far greater utility and long-term value.
