Despite its strengths, the QLn420's 203 dpi resolution might not suffice for applications requiring ultra-high definition printing. The device primarily supports direct thermal printing, limiting use to thermal-sensitive media and eliminating options for color or thermal transfer printing. Battery life, while generally sufficient, can vary with usage intensity and may necessitate frequent charging during heavy print volumes. The printer's maximum print width of 4 inches may be restrictive for some labeling requirements needing wider formats. Firmware updates and configuration may require some technical knowledge or proprietary Zebra software, which can be a barrier for inexperienced users. Additionally, the device lacks integrated NFC or cellular connectivity, which some contemporary mobile printers now offer for enhanced wireless options.
