Class: MarklifeDiscovery ​

PrinterDiscovery implementation for marklife printers.

Every chassis speaks Bluetooth; the P12 and P15 also expose a USB Printer-class interface, and none speaks TCP. The discovery surface is therefore:

  • Classic-BT SPP (the bulk of the catalogue) — openBluetoothSpp accepts an OS-paired RFCOMM device path (/dev/rfcomm0, /dev/tty.<Name>-SPPDev, COMx) plus a deviceKey. The user pairs at the OS level; SerialTransport.open opens the path.
  • BLE GATT — deferred. Node BLE (noble) is rough; for v1, openBluetoothGatt throws. Browser hosts use the web package's requestPrinterBluetooth factory.

listPrinters() returns an empty list because none of the supported transports are auto-enumerable to a specific marklife model from Node — Classic-BT pairing is OS-managed and BLE is deferred.

Constructors ​

Constructor ​

new MarklifeDiscovery(): MarklifeDiscovery

Returns ​

MarklifeDiscovery

Properties ​

family ​

readonly family: "marklife" = 'marklife'

Driver family identifier — matches DeviceEntry.family.

Implementation of ​

PrinterDiscovery.family

Methods ​

listPrinters() ​

listPrinters(): Promise<DiscoveredPrinter[]>

Returns an empty list — no auto-enumeration in v1.

Classic-BT SPP printers don't surface a model identifier on their RFCOMM channel, so we can't bind a registry entry without a user-provided deviceKey. BLE enumeration is deferred until a Node BLE backend is wired in.

Returns ​

Promise<DiscoveredPrinter[]>

Implementation of ​

PrinterDiscovery.listPrinters

openBluetoothGatt() ​

openBluetoothGatt(_options): Promise<MarklifePrinter>

Open a BLE printer.

Deferred in v1 — Node BLE backends (noble) are rough and the BLE Profile A / B / C dispatch layer is non-trivial. Browser hosts use @thermal-label/marklife-web's requestPrinterBluetooth(modelKey) factory, which surfaces the Web Bluetooth picker with the right service UUID.

Parameters ​

_options ​
deviceKey ​

DeviceKey

Returns ​

Promise<MarklifePrinter>

Throws ​

always.

openBluetoothSpp() ​

openBluetoothSpp(options): Promise<MarklifePrinter>

Open a Bluetooth-SPP printer by OS-paired RFCOMM path.

On Linux: /dev/rfcomm0 (after rfcomm bind or rfcomm connect). On macOS: /dev/tty.<Name>-SPPDev (after Bluetooth pairing). On Windows: COMx (after pairing in the Bluetooth settings). The deviceKey is required because RFCOMM carries no protocol-binding information.

Parameters ​

options ​
baudRate? ​

number

deviceKey ​

DeviceKey

serialPath ​

string

Returns ​

Promise<MarklifePrinter>

openPrinter() ​

openPrinter(options?): Promise<MarklifePrinter>

Open a printer.

  • serialPath + deviceKey → opens an OS-paired Bluetooth-SPP port via SerialTransport.
  • host → throws (no TCP transport in this catalogue).
  • vid+pid → throws (no USB transport).

Use openBluetoothSpp / openBluetoothGatt directly for the marklife-specific surface.

Parameters ​

options? ​

OpenOptions = {}

Returns ​

Promise<MarklifePrinter>

Implementation of ​

PrinterDiscovery.openPrinter
