universal_printer_flutter 0.0.2

Discover (Epson/Sunmi/Zebra/Star/SNMP/USB) and print ESC/POS receipts to network, USB, Star and Sunmi/iMin printers. Full on Android; network + Star on iOS.

Changelog

0.0.2

• Built-in printer discovery: discoverBuiltIn() detects the host device's own Sunmi/iMin printer (via the vendor print-service package) and is folded into discoverAll().
• PrinterConnectionType.builtIn + DiscoveredPrinter.isBuiltIn; new PrinterBrand.imin.
• Supported paper size: DiscoveredPrinter.supportedPaperWidthsMm (e.g. [58] / [80]), queried live from the vendor SDK for built-in printers.

0.0.1

• Initial Android implementation: a federated Flutter plugin wrapping the Universal Printer Kotlin SDK over a MethodChannel.
• Discovery: Epson (ENPC), Sunmi (mDNS), Zebra, SNMP (Bixolon/Citizen/Brother/Seiko), generic network (TCP-9100), USB — plus discoverAll and ping.
• Printing: ESC/POS network & USB, Star (StarXpand), Sunmi/iMin built-in; centralized PrintDocument builder with PrintType.text (native ESC/POS) and PrintType.image (HTML → WebView → bitmap); receiptHtml for previews.
• Impact/dot-matrix detection (isImpact) and effectiveEmulation default (ESC/POS).
• iOS: no-op stub that returns UNSUPPORTED_PLATFORM (no crash); Android-only for now.
