　　These models focus on standard office document output, with a printing width covering 210mm (A4 size), suitable for common paper documents such as contracts, reports, and proposal drafts. Battery capacity generally ranges from 1200mAh to 2000mAh; when fully charged, they can continuously print 80-150 A4 sheets (calculated based on 15 seconds per sheet). Print speed is mostly 50mm/s-80mm/s, which translates to 4-6 complete A4 documents per minute, meeting immediate needs such as on-site contract signing and on-site report printing. Representative models include the Deli DL-660W and Zebra ZD420, both supporting dual wireless connectivity (WiFi + Bluetooth) for quick pairing with mobile phones or laptops without relying on wired networks.

　　Portable Receipt/Label Models

　　These models emphasize small-format printing, with common widths of 58mm (cash register receipts) and 80mm (express waybills). Their weight is usually controlled between 300g and 500g, equivalent to the weight of a large-screen mobile phone, making them easy to carry in backpacks or pockets. Battery capacity typically ranges from 2000mAh to 3000mAh; when fully charged, they can print 300-500 58mm receipts or 200-300 80mm labels. Print speed is concentrated at 100mm/s-150mm/s, outputting 1-1.5 lines of text per second, suitable for scenarios such as couriers printing waybills on-site, retailers conducting off-site inventory checks, and service industries issuing instant certificates after on-site contract signing. Representative models include the HPRT MT800 and Epson EPSON TM-P80; some models also support multiple consumables such as waterproof paper and thermal label paper, adapting to different usage environments.

　　2. Key Purchasing Indicators (Avoiding Parameter Traps)

　　Battery Life: Focus on "Actual Printing Duration" Rather Than Just Capacity

　　For some manufacturers’ "2000mAh battery" claims, it is necessary to consider printing power consumption. For example, A4 models consume approximately 5W during printing, so a 2000mAh battery (3.7V) has an actual battery life of about 1.4 hours; while receipt models consume approximately 2W, so a battery of the same capacity can last 3.7 hours. When purchasing, prioritize checking the "continuous printing sheet count" data provided by the manufacturer, as it is more in line with actual usage scenarios. For food delivery models, verify "peak-hour battery life" (e.g., 400 orders/8 hours) instead of nominal capacity. For logistics models, confirm "12-hour duty cycle" (e.g., 1,000 waybills/day) to avoid mid-shift power depletion. For multi-size models, request "mixed-size battery endurance" (e.g., 300 58mm receipts + 50 A4 sheets) as larger formats drain power faster.

　　Print Speed: Distinguish Between "Maximum Speed" and "Stable Speed"

　　The "150mm/s" in parameter sheets is mostly the maximum instantaneous speed. When actually printing documents (especially those containing images or complex tables), the speed will drop to 80mm/s-120mm/s. When purchasing, you can consult customer service to obtain the "mixed document print speed" to avoid reduced office efficiency due to false speed claims. For food delivery, prioritize "stable speed ≥120mm/s" to handle batch orders with special instructions (e.g., "less spicy"). For logistics, require "stable speed ≥200mm/s" to process bulk waybills with QR codes and sender/receiver details during peak e-commerce periods (e.g., Double 11). For multi-size models, confirm speed consistency across widths—e.g., ≥100mm/s for 80mm labels and ≥60mm/s for A4 docs.

　　Wireless Connectivity: Prioritize " Dual-Mode + Auto-Reconnection" Functions

　　In mobile office scenarios, WiFi is susceptible to environmental interference, and Bluetooth connectivity offers better stability. It is recommended to choose models that support both WiFi (5GHz + 2.4GHz dual-band) and Bluetooth 5.0 or above. Some high-end models feature an "auto-reconnection after disconnection" function, which reduces the trouble of repeated pairing during field work and improves operational fluency. For food delivery, select models with "WiFi + 4G" dual-network redundancy and 100ms fast reconnection. For logistics, opt for "Bluetooth 5.2 + 4G LTE" with cloud synchronization—critical for couriers working in remote areas with weak WiFi. For multi-size models, ensure connectivity supports cross-device switching (e.g., phone for receipts, laptop for A4 docs) without re-pairing.

　　Consumable Compatibility: Avoid "Proprietary Consumable Binding"

　　Some brand models only support their own thermal paper, which increases long-term usage costs. It is recommended to choose models compatible with universal thermal paper specifications (e.g., A4 models compatible with 210mm × 30m universal thermal roll paper, receipt models compatible with 58mm × 40m universal thermal roll paper), allowing more flexible subsequent consumable purchases. For food delivery, opt for printers compatible with oil-resistant thermal paper (10-year fade resistance) to prevent smudging from food grease. For logistics, ensure compatibility with universal pressure-sensitive adhesive thermal labels (80mm×180mm, 100mm×190mm) and synthetic paper for humid/wet environments—avoid proprietary labels that cost 30% more. For multi-size models, confirm compatibility with universal roll diameters (up to 127mm recommended) and thicknesses (40-120μm) to avoid jamming.

　　Food Delivery-Specific Reliability Metrics

　　Platform Adaptation: Confirm compatibility with local delivery platforms (e.g., Uber Eats, DoorDash) via manufacturer’s API list.

　　Offline Capability: Ensure 50+ order cache capacity and cloud synchronization.

　　Environmental Resistance: IP54 rating for kitchen oil/dust (back-of-house use) or IP42 + 1.5m drop resistance for riders.

　　Logistics-Specific Reliability Metrics

　　Platform & System Integration: Verify SDK/API support for major logistics platforms (SF Express, Cainiao, JD Logistics) and WMS/ERP systems via the manufacturer’s certification list.

　　Waybill Compatibility: Support 76mm (3-ply), 80mm (standard), and 100mm (large) electronic waybills; accommodate gap/adhesive-backed labels without jamming.

　　Durability: IP54 rating for warehouse dust/oil or IP42 + 1.5m drop resistance for couriers (e.g., HPRT HM-A300E).

　　Intelligent Management: Cloud-based device monitoring, remote configuration, and order log tracking (critical for fleet operations).

　　Multi-Size-Specific Adaptability Metrics

　　Adjustment Convenience: Prioritize tool-free width adjustment (e.g., sliding guides vs. screw-fastened parts) to minimize downtime during size switches.

　　Detection Accuracy: Ensure dual sensors (transmissive + reflective) for auto-detecting paper type/size and avoiding misalignment.

　　Media Versatility: Support continuous paper, black-mark paper, and adhesive labels across all compatible widths—avoid models limited to plain thermal paper.

　　Mechanical Durability: Check for reinforced paper paths (e.g., stainless steel guides) to handle frequent size changes without wear.

　　3. Scenario-Specific Selection Recommendations

　　For frequent printing of A4 documents such as contracts and proposals: Prioritize A4 models with a battery capacity of 1800mAh or above and a print speed of ≥60mm/s. Match them with apps that support direct PDF printing (e.g., some models are compatible with WPS and Adobe Acrobat for direct output) to reduce file format conversion steps.

　　For mainly printing express waybills and cash register receipts: Choose portable receipt models with a weight of ≤400g and a battery capacity of 2500mAh or above. Prioritize styles with the "auto paper cutting" function to avoid uneven edges and consumable waste caused by manual paper tearing.

　　For outdoor or humid environments (e.g., logistics warehousing, seafood markets): Pay extra attention to the device’s protection level and select products with an IP54 or higher dustproof and waterproof rating (such as the Honeywell Odyssey 1200) to prevent dust and splashing water from affecting the device’s service life.

　　For restaurant back-of-house food delivery orders: Select 80mm models with 160mm/s speed (e.g., Sunmi 58 Cloud Printer), dual-network connectivity, and auto-order voice alerts. Pair with oil-resistant thermal paper to handle 200+ daily orders.

　　For delivery riders: Choose 58mm ultra-portable models (≤300g) with 3000mAh battery (e.g., SNBC BTP-P33), IP42 protection, and 4G module. Prioritize 1-minute fast charging (100 orders per 10-minute charge) for emergency use.

　　For small food stalls with limited space: Opt for all-in-one models (e.g., HPRT MT800 + delivery app integration) that support both order printing and payment receipt output, reducing equipment clutter.

　　For couriers (on-site pickup): Select 80mm portable models (≤450g) with 3000mAh battery (e.g., HPRT HM-A300E), 1.5m anti-drop performance, and Bluetooth 5.2. Prioritize 203DPI resolution to ensure barcode scannability and offline cache for 100+ orders.
