| Paper width | 58mm nominal roll width | Confirm the printer accepts the roll width you need. The printable area is usually narrower than the paper itself. | Check supported roll width, maximum roll diameter, and whether your receipt layout fits. |
| Print resolution | 203 dpi is common in compact receipt printers | This is generally suitable for receipts, simple logos, and basic barcodes. Fine details depend on printhead quality and software settings. | Print a sample containing small text and the barcode types used in your workflow. |
| Body size and portability | Dimensions vary by design; portable units are made for handheld or bag carry | A smaller body is easier to carry, while a larger roll compartment can reduce how often you reload paper. | Compare the published dimensions with your belt pouch, counter space, or storage compartment. |
| Weight | Depends on the enclosure, battery, and roll capacity | Lower weight can be more comfortable for frequent handheld use; include the battery when comparing specifications. | Check whether the listed weight includes the battery and paper roll. |
| Battery capacity and runtime | Capacity and runtime differ substantially between models and usage conditions | A larger battery may extend use between charges, but print volume, wireless connection, battery age, and standby time also affect runtime. | Look for a stated test method or a realistic estimate of receipts per charge; confirm charging time and battery replacement options. |
| Print speed | Varies by printhead and model; published speeds are usually maximum rates | Higher speed can help at busy checkout points, but actual output may be slower with dense graphics or long receipts. | Compare a typical receipt print, not only the headline maximum speed. |
| Connectivity | Common options include Bluetooth and USB; availability varies | Choose a connection supported by the phone, tablet, or computer used for printing. | Verify operating-system compatibility, pairing steps, and whether a required app or driver is available. |
| Paper loading and controls | Designs range from simple drop-in loading to more involved roll installation | A clear cover, accessible feed button, and status indicators make routine use easier. | Check whether paper can be loaded quickly and whether the device clearly signals low battery or an open cover. |
| Thermal paper and operating conditions | Direct thermal printing uses heat-sensitive paper and does not require ink or toner | Printed output can fade with heat, sunlight, friction, or prolonged storage; paper quality affects readability. | Confirm compatible paper and follow the manufacturer’s storage and temperature guidance. |
| Best-fit use case | Portable models suit mobile receipts; larger units may be more convenient for frequent counter use | Balance portability, paper capacity, connection type, and expected print volume rather than choosing by size alone. | Test the printer with your device, app, receipt format, and a full work shift’s expected usage where possible. |
