Live demos
Browse the sample list on the left and preview layouts plus sample code on the right. Run a demo to print silently or preview PDF via web-print-pdf and the local client. Install and launch the client first.
Client
If results look wrong, install the latest Web Print Expert client from our site first (older builds may cause layout drift).
Layout
Preview and print follow standard HTML/CSS only—no hidden tricks. What you style is what you get.
15 - Header & footer
displayHeaderFooter with header/footer templates; use the page-number demo for page numbers.

Sample code
await webPrintPdf.printHtml(html, {
paperFormat: 'A4',
displayHeaderFooter: true,
headerTemplate: '<div style="font-size:16px;width:100%;text-align:center;color:#333">Web打印专家 · 演示拣货清单</div>',
footerTemplate: '<div style="font-size:14px;width:100%;text-align:center;color:#666">打印时间 <span class="date"></span> · 演示数据,仅供联调</div>',
margin: { top: '18mm', bottom: '18mm' }
}, {
paperFormat: 'A4'
});
Result
- Demos load bundled
web-print-pdffirst (same API as npm); CDN is used as fallback. - The client’s built-in Run examples page has more editable demos; this page complements it.
- Utility demos (connection, printer list) return JSON only—no print job.
