Image printing from Bitmap or directly from a View
+ *
Utilities to choose/save the target printer and paper width (2"/3")
+ *
+ *
+ *
Quickstart:
+ *
{@code
+ * // Requires android.permission.BLUETOOTH_CONNECT on Android 12+
+ * Printama.with(context, printama -> {
+ * printama.printTextln("Hello Printer!", PA.CENTER);
+ * printama.feedPaper();
+ * printama.close();
+ * });
+ *
+ * // Or get an instance directly (uses the saved/default printer)
+ * Printama p = Printama.with(context);
+ * p.printTextln("Hello", PA.LEFT);
+ * p.close();
+ * }
+ *
+ *
Threading:
+ *
+ *
Most text APIs are lightweight and can be called on the main thread.
+ *
Image-heavy operations (e.g., printFromView) offload work to a background thread internally.
+ *
+ *
+ *
Permissions:
+ *
+ *
Callers must hold {@code android.permission.BLUETOOTH_CONNECT} at runtime on Android 12+.
+ *
+ *
+ *
Deprecated API notes:
+ *
+ *
Several constants and old parameter orders were deprecated in 1.0.0 and will be removed in 2.0.0.
+ * See each {@code @deprecated} tag for migration examples.
+ *
+ * @since 1.0.0
