z92_pos_printer_flutter_sdk 1.1.0

Android plugin for ZCS Z92 and Z91 built-in POS printers. Print text, columns, images, Code 128 barcodes, and QR codes.

Changelog

1.1.0

• Add printBatch with typed PrintCommand entries for text, columns, images, QR codes, Code 128 barcodes, separators, and feed. Append in order and submit once on the existing background queue, with a single readiness wait.
• Reject malformed/nested batches and prevent submission after invalid input, append failures, interruption, or engine detachment. Preserve buffer cleanup and never automatically retry a failed submission.
• Demonstrate batch printing in the example and document migration from individual commands. Existing printing APIs retain their behavior.

1.0.2

• Wait up to 10 seconds for a printing printer before submitting the next command, polling every 100 ms on the background queue with a monotonic deadline.
• Keep terminal printer errors, timeout, interruption, and engine detachment as failures without retrying print submission; preserve append-buffer cleanup.
• Include method, numeric status, and readiness/submission phase in failure logs.

1.0.1

• clear SDK print buffer after failed jobs
