Windows下Puppeteer生成PDF打印时宽大于高出现尺寸方向错误

使用Puppeteer加载HTML文件转换为PDF后，通过Node.js调用打印机打印。当PDF宽度小于高度时打印正常，但宽度大于高度时，打印机输出的尺寸和方向均出现错误。

const puppeteer = require('puppeteer');
const fs = require('fs');
const path = require('path');
const express = require('express');
const expressWs = require('express-ws');
const printer = require('pdf-to-printer');

let browser;

async function initializeBrowser() {
    if (!browser) {
        browser = await puppeteer.launch({
            headless: 'new',//'new'
        });
    }
}

async function printHtmlToCustomSize(page, htmlFilePath, outputPath, widthMM, heightMM, printerName) {
    await page.setViewport({
        width:  widthMM* 25.4,
        height: heightMM * 25.4,
        deviceScaleFactor: 2,
    });

    const fileUrl = `file://${path.resolve(htmlFilePath)}`;
    console.log(fileUrl);

    await page.goto(fileUrl);

    await page.pdf({
        path: outputPath,
        width: `${widthMM}mm`,
        height: `${heightMM}mm`,
    });

    const printerOptions = {
        printer: printerName,
    };

    await printer.print(outputPath, printerOptions);
    console.log(`PDF printed to ${printerName}`);
}

async function startServer() {
    const app = express();
    expressWs(app);

    app.ws('/print', (ws, req) => {
        ws.on('message', async (message) => {
            const { htmlFilePath, outputPath, widthMM, heightMM, printerName } = JSON.parse(message);

            await initializeBrowser();
            const page = await browser.newPage();

            try {
                await printHtmlToCustomSize(page, htmlFilePath, outputPath, widthMM, heightMM, printerName);
                ws.send(JSON.stringify({ status: 'success' }));
            } finally {
                await page.close();
            }
        });
    });

    app.listen(3000, () => {
        console.log('WebSocket server listening on port 3000');
    });
}

startServer();

• 实际打印：内容尺寸缩放错误，方向偏移，无法匹配设定的宽高
• 预期打印：内容完整贴合设定的宽高布局，位置准确
