| Driver Type | Purpose | Download Source | |-------------|---------|----------------| | | Windows (USB, Serial, Parallel) – supports OPOS, JavaPOS, EPSON OPOS ADK | Epson support site | | Linux CUPS driver | For use with tm-cups (Epson’s CUPS filter) | Epson download center | | OPOS / JavaPOS | POS applications (retail, hospitality) | Epson OPOS ADK | | ESC/POS SDK | Mobile/embedded (Android, iOS, Linux) | Epson ePOS SDK | Development approach : Use these drivers and call standard printing APIs (e.g., Windows PrintDocument , Linux lp , or POS commands). 2. Raw ESC/POS Command Development If you need full control (custom logos, barcodes, cash drawer kick, paper cutting), send ESC/POS sequences directly. Common ESC/POS commands for TM-U220: | Function | Command (hex) | |----------|--------------| | Initialize printer | 1B 40 | | Print text (normal) | raw text + 0A | | Select character font | 1B 21 n | | Open cash drawer | 1B 70 0 25 250 (pin 2) | | Paper full cut | 1B 69 | | Partial cut | 1B 6D | Example (Windows C# – raw USB): using System.IO.Ports; using System.Runtime.InteropServices; // For USB-to-virtual COM or native USB via WinUSB public void PrintRaw(byte[] data)
To develop or work with a driver for the (a popular impact receipt printer), you don’t typically write a driver from scratch. Instead, you integrate using existing drivers or issue raw ESC/POS commands.
sp.Open(); sp.Write(data, 0, data.Length);
// Using serial (if TM-U220 serial or USB virtual COM) using (SerialPort sp = new SerialPort("COM3", 9600, Parity.None, 8, StopBits.One))
