A Flutter plugin to capture a web URL as a PNG image sized for thermal receipt printers (e.g., 384/576 dots) using platform WebView rendering.
web_uri_to_image #
Render a web URL to a PNG image sized for thermal receipt printers (ESC/POS).
Designed for stable printing: control width (in printer dots), scale, and render delay.
Why this package? #
Thermal printers expect a fixed pixel width (dots/line). Typical widths:
- 58mm receipts: 384 dots
- 80mm receipts: 576 dots
This plugin renders a web page at an exact width and returns PNG bytes you can feed into your ESC/POS image command pipeline.
Features #
- Capture URL → PNG bytes (Uint8List)
- Specify target width in printer dots (e.g., 384/576)
- Adjustable
scale,delayMs, andtimeoutMs - Optional transparent background (useful for some layouts)
