Bluetooth thermal printers have become an essential tool across multiple sectors, with a diverse range of models available to meet different user needs. Understanding the classification of these printers can assist businesses and individuals in making informed purchasing decisions.

　　Based on Size and Portability

　　Ultra - Portable Printers: These printers are designed for maximum mobility. They are compact in size, often small enough to fit in a pocket or a small bag. Delivery couriers frequently use ultra - portable Bluetooth thermal printers. For example, companies like DHL or FedEx may equip their drivers with such printers to print out proof - of - delivery receipts on the go. These printers typically run on rechargeable batteries, offering extended operation time between charges. Their lightweight construction ensures that users can carry them throughout the day without discomfort.

　　Desktop Printers: Slightly larger in size, desktop Bluetooth thermal printers are more suitable for fixed - location use. In a retail store, a desktop printer can be placed at the checkout counter. It can handle a larger volume of printing tasks compared to portable models. Desktop printers usually have a more robust paper - feeding mechanism, allowing for continuous printing of receipts, labels, or invoices. Some models are even designed to be integrated with point - of - sale (POS) systems, streamlining the transaction process.

　　Based on Functionality

　　Basic Receipt Printers: As the name suggests, these printers are primarily used for printing receipts. They are commonly found in restaurants, cafes, and small retail shops. Basic receipt printers are optimized for fast and efficient receipt printing. They often support standard thermal paper widths, such as 58mm or 80mm. These printers may have limited additional features, focusing mainly on delivering clear and legible receipts.

　　Label Printers: Label - specific Bluetooth thermal printers are designed for applications that require the printing of labels. In a warehouse or a logistics center, label printers are used to print shipping labels, barcodes, and product labels. These printers can print high - resolution graphics and barcodes, ensuring accurate identification and tracking of goods. Some label printers come with advanced software that allows users to design custom labels, adding text, logos, and variable data.

　　Multi - Function Printers: These printers combine the capabilities of receipt, label, and even document printing. In a healthcare setting, a multi - function Bluetooth thermal printer can be used to print patient wristbands, prescription labels, and medical reports. Multi - function printers offer greater versatility, eliminating the need for multiple printers in an office or a business. They usually come with more advanced connectivity options, such as Wi - Fi in addition to Bluetooth, enabling seamless integration with various devices and systems.
