Posrender

A .NET library that parses an ESC/POS byte stream and renders it as a PNG image, reproducing what an Epson label printer would physically print. Useful for generating label previews in applications that drive POS printers.

Installation

dotnet add package Posrender

Usage

using Posrender;

byte[] escPosData = /* raw ESC/POS command stream */;

// Render with default options (80 mm Epson printer, 203 DPI)
Stream png = PosRenderer.Render(escPosData);

// Render with custom paper width
var options = PosRenderOptions.FromMillimeters(58);
Stream png = PosRenderer.Render(escPosData, options);

// Write to file
using var file = File.Create("label.png");
png.CopyTo(file);

Options

Property Default Description
PaperWidthDots 576 Paper width in dots (≈ 72 mm printable area at 203 DPI)
Dpi 203 Printer resolution

Use PosRenderOptions.FromMillimeters(widthMm, dpi) to compute the dot width from physical dimensions.

Supported ESC/POS commands

Command Description
ESC @ Initialize printer
ESC a n Text alignment (left / center / right)
ESC E n Bold on/off
ESC - n Underline (none / single / double)
ESC ! n Print mode (bold, double-height, double-width, underline)
ESC M n Font select (A / B)
ESC d n Feed n lines
GS ! n Character size (width × height multiplier)
GS v 0 Print raster image
GS ( k QR code (rendered as a placeholder rectangle)
GS V Paper cut (ignored)
Printable bytes Text output
