Installation

npm install @dymo-print-suite/core
# or
pnpm add @dymo-print-suite/core
# or
yarn add @dymo-print-suite/core

Usage

Note: Examples use async/await syntax. For CommonJS or environments without top-level await, wrap calls in an async function.

Print a Label

import { printLabel } from "@dymo-print-suite/core";

async function print() {
  const labelXml = `<?xml version="1.0" encoding="utf-8"?>
<DieCutLabel Version="8.0" Units="twips">
  <!-- Your label XML -->
</DieCutLabel>`;

  await printLabel("DYMO LabelWriter 450", labelXml);
}

print();

Build Custom Requests

import { dymoRequestBuilder } from "@dymo-print-suite/core";

async function fetchPrinters() {
  const response = await dymoRequestBuilder({
    method: "GET",
    wsAction: "getPrinters",
  });

  console.log(response.data);
}

fetchPrinters();

Parse Printer List from XML

import { getDymoPrintersFromXml } from "@dymo-print-suite/core";

const printers = getDymoPrintersFromXml(xmlResponse, "LabelWriterPrinter");

printers.forEach((printer) => {
  console.log(`${printer.name}: ${printer.isConnected ? "Online" : "Offline"}`);
});

Request Cancellation

import { dymoRequestBuilder, isRequestCancelled } from "@dymo-print-suite/core";

async function fetchWithCancellation() {
  const controller = new AbortController();

  // Cancel after 5 seconds
  setTimeout(() => controller.abort(), 5000);

  try {
    const response = await dymoRequestBuilder({
      method: "GET",
      wsAction: "status",
      signal: controller.signal,
    });
    console.log(response.data);
  } catch (error) {
    if (isRequestCancelled(error)) {
      console.log("Request was cancelled");
    }
  }
}

fetchWithCancellation();
