imin_printer 0.7.0

Add label printing API and call examples

Changelog

0.7.0 - 2026-03-24

Note: All new features below are only available on Android 13 (API 33) and above devices using SDK 2.0. On older devices (SDK 1.0), these methods will be silently ignored.

以下新增功能仅适用于 Android 13 (API 33) 及以上设备（SDK 2.0）。在旧设备（SDK 1.0）上调用这些方法会被静默忽略。

Bug Fixes

• Fix setTextBitmapLetterSpacing calling wrong method internally (修复setTextBitmapLetterSpacing内部调用错误方法)
• Fix setTextWidth calling wrong MethodChannel name (修复setTextWidth调用了错误的MethodChannel名称)
• Fix printText with style not working on SDK 2.0 devices — now auto routes to printTextBitmap path (修复2.0设备上printText带style参数无效的问题，自动走位图打印路径)
• Fix LabelCanvasStyle missing enableReverse and enableMirror fields (修复LabelCanvasStyle缺少enableReverse和enableMirror字段)

New Features — ESC/POS Font Control (2.0 SDK)

Important: These methods only take effect when used with printEscPosText or printText (without style). They do NOT affect printTextBitmap. These are global settings — you must manually reset them after use (e.g. setFontBold(false) or call initPrinterParams()), otherwise they will affect all subsequent prints.

重要提示：这些方法仅对 printEscPosText 或不带 style 的 printText 生效，对 printTextBitmap 无效。这些是全局配置，使用后需手动还原（如 setFontBold(false) 或调用 initPrinterParams()），否则会影响后续所有打印。
