Receipt Printing

An educational, vendor-neutral reference on receipt and point-of-sale printing: how thermal receipt printers work, the paper and roll formats they use, the command sets and standards that drive them (ESC/POS, UnifiedPOS/OPOS), connectivity to POS systems and cash drawers, and the durability trade-offs of thermal media. Scope stays on receipt/POS printing concepts, not product marketing, rankings, or purchase advice.

Planned coverage

What Is a Receipt Printer? — Defines POS/receipt printers and how they differ from general-purpose office printers in form, media, and command interface.
How Thermal Receipt Printers Work — Explains the thermal printhead, heat-sensitive coating, and line-by-line printing mechanism of a direct thermal receipt printer.
Direct Thermal vs Thermal Transfer in Receipt Printing — Compares the two thermal methods, why receipts typically use direct thermal, and where thermal transfer applies instead.
Receipt Paper Sizes Explained (58mm and 80mm) — Describes common roll widths, diameters, and core sizes and how they map to printer models and column counts.
How Receipt Auto-Cutters Work — Explains full vs partial cut mechanisms and how the cut is triggered by print commands.
Receipt Printer Connectivity: USB, Ethernet, and Bluetooth — Vendor-neutral overview of the physical and wireless interfaces used to attach a receipt printer to a POS.
How Cash Drawers Connect to Receipt Printers — Explains the drawer kick-out signal sent through the printer and the RJ-style connector used for it.
Impact vs Thermal Receipt Printers — Compares dot-matrix impact receipt printers with thermal units, including kitchen/heat-tolerant use cases.
Why Thermal Receipts Fade Over Time — Explains the chemistry of heat-sensitive coatings and the heat, light, and friction factors that cause fading.
BPA and BPA-Free Thermal Paper — Educational overview of developer chemicals in thermal paper and what BPA-free and phenol-free labeling means.
What Are UnifiedPOS and OPOS? — Explains the vendor-neutral device standards that let POS software drive receipt printers and peripherals.
Kitchen Printers in Restaurants — Explains why kitchens often use impact printers and how order tickets route from a POS to remote printers.
How Receipt Printer Drivers Work — Explains raw/ESC-POS driving vs OS printer drivers and why POS apps often bypass generic drivers.
Understanding Receipt Print Density and Speed — Explains dots-per-line, print speed in mm/s, and how density settings affect legibility and paper longevity.
Storing and Handling Thermal Receipt Rolls — Best practices for storing thermal media to avoid premature activation, based on the material's heat and solvent sensitivity.
Connecting a Receipt Printer to a POS System — Step-through of pairing a receipt printer with POS software over USB, network, or Bluetooth.
Setting Up a Network Receipt Printer — How Ethernet/Wi-Fi receipt printers get an IP address and are addressed by POS terminals.
Printing Receipts from a Tablet POS — How tablet-based POS apps drive Bluetooth or network receipt printers, and the role of ESC/POS.
Receipt Roll — Defines the paper roll consumable, its width/core/diameter dimensions, and thermal vs plain-paper types.
Auto-Cutter — Defines the automatic paper-cutting mechanism and full vs partial cut.
Cash Drawer Kick-Out — Defines the electrical pulse a printer sends to open an attached cash drawer.
Point-of-Sale Terminal — Defines a POS terminal and its relationship to the attached receipt printer and peripherals.
