| Paper width and print width | Confirm the supported roll width and the printer’s actual printable width. | 80 mm roll support; printable width is commonly around 72–72.8 mm, depending on the model. | Essential | “80 mm” usually describes the paper roll, not the full width of the printed area. |
| Print speed | Compare the rated speed and consider the complexity of typical receipts. | Many desktop receipt printers are rated roughly between 150 and 300 mm/s; actual results vary with content and settings. | High | Higher speed can reduce queues in busy checkout environments, but a published maximum is not always the speed achieved in everyday use. |
| Print resolution | Check the dot density and test small text, logos, and barcodes. | 203 dpi is common for thermal receipt printers. | High | Resolution affects the clarity of fine text and graphics; correct print settings and paper also influence readability. |
| Host connections | Match the ports and wireless options to the POS terminal and network. | USB is common; Ethernet, serial, Bluetooth, and Wi-Fi are available on selected models. | Essential | Confirm the exact interface combination, device compatibility, and whether any required cables or adapters are included. |
| Operating-system and POS compatibility | Verify supported operating systems, drivers, SDKs, and POS software integrations. | Check compatibility with the specific checkout device and application before purchase. | Essential | A printer can have suitable hardware but still require a compatible driver, command set, or integration to work with a POS system. |
| Auto-cutter | Check whether the printer has a cutter, the cut type, and the stated cutter life. | Full or partial cutting is model-dependent; compare the manufacturer’s rated cutter life with expected daily use. | High | Automatic cutting speeds up checkout, while cutter specifications help assess maintenance needs over time. |
| Paper loading and roll capacity | Look for drop-in loading, a clear paper-out indicator, and the supported roll diameter. | Roll capacity varies by model; verify the maximum roll diameter and core requirements in the specifications. | High | Easy loading and fewer roll changes can simplify daily operation, especially at busy counters. |
| Reliability and duty cycle | Review the warranty, support terms, and any published printhead or cutter life ratings. | Use stated manufacturer ratings for comparison; there is no single service-life figure that applies to all 80 mm printers. | High | Published component ratings and accessible support are more useful for planning than assuming all printers have the same lifespan. |
| Counter space and mounting | Measure the printer footprint and check for wall-mounting or vertical-placement options if needed. | Dimensions and approved mounting positions vary by model. | Medium | A suitable footprint helps keep the checkout area organized and ensures the paper cover remains accessible. |
| Power and energy requirements | Check the supplied power adapter, input requirements, and power-saving features. | Use the voltage and adapter specified for the selected printer; do not assume adapters are interchangeable. | Medium | Correct power equipment supports reliable operation and avoids compatibility or safety issues. |
| Thermal paper requirements | Confirm compatible roll width, diameter, core, and paper quality recommendations. | Direct thermal printing uses heat-sensitive paper and does not require ink or toner. | High | Suitable thermal paper supports legible receipts and helps prevent avoidable loading or print-quality problems. |
| Total cost of ownership | Compare purchase price, paper use, warranty, service availability, and replacement parts. | Assess expected operating costs over the intended service period rather than comparing purchase price alone. | High | A lower upfront price may not be the best value if consumables, repairs, or support are difficult to manage. |
