Project description:
"I’m building a single thermal printing solution that my web app and companion Android / iOS apps can all talk to in exactly the same way, regardless of whether the user connects over Bluetooth, Wi-Fi or a straight USB cable. The device must switch seamlessly between printing 110 mm-wide receipts and 100 mm-wide adhesive labels without needing manual recalibration each time.

Here’s what I need from you:

• Recommend—or design—the actual printer mechanism and controller board that can physically handle both media types at the stated widths.
• Develop or supply firmware plus a simple cross-platform SDK / REST or ESC/POS-style command set so the browser, Flutter, React Native or native code can call print() and get identical output on every interface.
• Provide a demo page and sample Android & iOS projects that show printing over all three connection methods.
• Include clear documentation for integrating the printer into third-party web POS and mobile inventory apps.

Acceptance is straightforward: I will load the sample projects, pair or plug in the printer, hit “print” from browser, Android and iOS, and receive a correctly scaled test receipt and label on the first try.

If you already have a proven board or firmware that fits these specs, let’s move fast; otherwise outline your proposed hardware, chipset, driver approach and timeline in your reply." (client-provided description)
