[REQUEST] Extending support for Ablemark M60 aka. Marklife X2 thermal printer

[TC-Patrick]

Hey,

I just got a Marklife X2 thermal printer (also sold as the Ablemark M60 on amaz*n) and wanted to see if I could get it working. Thanks to the profile guide, I was able to find the BLE device and connect to it, but I haven't been able to actually print anything yet.

Here's the profile I'm using:

import type { DeviceProfile } from "../types.js";

export const m60Profile: DeviceProfile = {
  modelId: "m60",
  protocolId: "l11",                          // reuse existing protocol
  serviceUuid: "0000ff00-0000-1000-8000-00805f9b34fb",
  characteristics: {
    tx: "0000ff02-0000-1000-8000-00805f9b34fb",
    rx: "0000ff01-0000-1000-8000-00805f9b34fb",
    cx: "0000ff03-0000-1000-8000-00805f9b34fb", // optional — omit if no flow control char
  },
  packetSize: 95,                              // BLE write chunk size in bytes
  flowControl: {
    starvationTimeoutMs: 1000,
    packetDelayMs: 30,
  },
  defaults: { density: 2, paperType: "gap" },  // "gap" for label paper, "continuous" for receipt
  namePrefixes: ["X2", "M60"],                 // BLE advertised name prefixes
};

The reason I'm looking into this is that the printer is set up for sticky thermal labels, but I want to use standard 58mm thermal paper instead.
When I print on regular paper, I get small gaps between the printed images and text. Not sure if that's a hardware limitation or something configurable. I did notice some print settings in the reverse-engineered SDK that might help fix the gaps.

I'm happy to help with testing and adding support for this printer. If you're on Discord, we could probably figure this out pretty quickly.

Hello @TC-Patrick, happy to support this model. I will have a look and will ad a profile for it :)

Please drop me your discord handle, so that we can speedup the debugging

The M60/X2 uses a different protocol than L11. It needs zlib-compressed bitmaps and a different command set. That's why printing didn't work with the L11 profile.

I've added full X2 protocol support and it's released now. Can you give it a try? Both gap and continuous paper types are supported.

Let me know how it goes!
