　　Fast switching between multiple devices: Supports simultaneous memory of 5 commonly used devices (such as mobile phones, tablets, laptops), no need for repeated pairing, and the response time for switching devices to print is ≤3 seconds, adapting to mobile team scenarios with multi-person collaboration;

　　Network-free direct connection is more flexible: No need to rely on WiFi or wired networks, just turn on Bluetooth on the mobile phone to pair and print, especially suitable for scenarios without network coverage such as outdoor and remote areas (such as printing inspection records in field inspections, printing certificates for on-site services in rural areas).

　　2. Long-Life Battery Configuration: Free from Power Supply, Available All Day

　　Large-capacity battery support: Built-in 2000mAh-4000mAh rechargeable lithium battery (3000mAh for mainstream models), which can print 150-300 A5 documents (or 300-500 58mm receipts) continuously on a full charge, meeting the needs of 1-2 days of on-site work;

　　Fast charging + low power consumption dual optimization: Supports Type-C fast charging (50% charged in 30 minutes, fully charged in 2 hours), no long waiting time in emergency scenarios; standby power consumption ≤5mA (even lower in Bluetooth sleep state), continuous standby time up to 72 hours, avoiding frequent charging affecting work rhythm.

　　3. Mini Portable + Durable Design: Adapt to Complex Mobile Scenarios

　　Ultra-light wireless body: Weight is only 300-500g (equivalent to a thin and light tablet), size is mostly 12cm×8cm×5cm (holdable in the palm), can be easily put into pockets and briefcases, no burden to carry on-site; some models adopt foldable paper outlets, which reduce the volume by another 20% after storage, saving space;

　　Durability adapts to outdoor use: The body shell is made of ABS anti-drop material (can withstand a 1.2-meter drop to a hard ground), the print head supports a service life of 100 kilometers (equivalent to printing 500,000 documents), the operating temperature range is -10℃~50℃, and the humidity tolerance is ≤85%RH, adapting to outdoor high temperature, humidity or slightly bumpy scenarios (such as construction sites, outdoor exhibitions).

　　4. Thermal Ink-Free + High-Definition Printing: Balancing Cost and Quality

　　Ink-free design reduces cost and worry: Adopts thermal printing technology, which develops color on thermal paper by heating the print head, no need for ink cartridges, ribbons and other consumables. The cost per print is only 0.05-0.1 yuan (traditional inkjet printing is about 0.3-0.5 yuan per sheet), and it avoids ink leakage polluting documents or equipment;

　　High-definition output meets needs: Printing resolution reaches 203DPI-300DPI (203DPI for mainstream models), which can clearly present 8-point font, tables, QR codes and barcodes, meeting the printing needs of documents requiring high clarity such as contract terms, inspection reports and product labels. It supports multiple paper widths such as A5, 58mm and 80mm (A5 for contracts, 80mm for receipts, 58mm for small labels).

　　5. Minimalist Operation: Zero-Threshold Start, No Professional Settings Required

　　One-click pairing and printing: After turning on Bluetooth on the mobile phone, search for the device name and click to pair to connect. The supporting APP supports two-step operation of "select document - click print", no need to install complex drivers (compatible with Android and iOS systems, no need to distinguish mobile phone brands);

　　Full compatibility with document formats: The APP supports mainstream formats such as Word, Excel, PDF, JPG and TXT, and can directly print documents stored in mobile phones, email attachments, or scan paper documents through the APP and then print. It even supports quick printing of files received via WeChat and QQ, adapting to the document type needs of daily mobile office.

　　3. Typical Application Scenarios: Focus on High-Frequency Needs of "Wireless Mobility"

　　1. On-Site Sales Contract Scenario

　　When sales staff visit customers outside the company, they can connect the printer via mobile phone Bluetooth to print contracts, quotations and customer demand confirmation forms in real time, without carrying a laptop or relying on the customer's printer; if the contract terms need to be modified temporarily, they can reprint within 3 seconds after editing on the mobile phone, realizing the one-stop process of "on-site communication - confirmation - signing" and shortening the contract signing cycle.

　　2. On-Site Service Certificate Scenario

　　In on-site scenarios such as home appliance maintenance, housekeeping services and express delivery signing, technicians can connect the printer via mobile phone Bluetooth to print service work orders, warranty certificates and sign-in documents on site. Customers can sign and confirm on the spot, avoiding the trouble of "supplementing documents afterwards"; it supports custom document templates (such as maintenance items and cost details), improving service professionalism.

　　3. On-Site Inspection Record Scenario

　　When engineers conduct inspections in construction sites, computer rooms and parks, they can connect the printer via tablet Bluetooth to print inspection records (including equipment status and problem descriptions) in real time, and ask the person in charge to sign on the spot, avoiding errors in later transcription of paper records; when encountering equipment failures, they can print equipment parameter sheets and maintenance guidelines, reducing reliance on viewing documents on the mobile phone screen.

　　4. Mobile Teaching/Retail Scenario

　　Teachers in training institutions can print exercises and teaching materials via tablet Bluetooth when teaching outside, without carrying a USB flash drive or looking for a print shop; small mobile stalls (such as market stalls and mobile food carts) can print consumption receipts and product labels. The mobile phone Bluetooth direct connection is easy to operate, no additional computer configuration is required, and the equipment investment cost is reduced.

　　4. Maintenance and Selection Guide: Focus on Bluetooth and Mobile Adaptation
