Tauri Plugin: tauri-plugin-printing-ext

A Tauri plugin for extending printing functionality. This plugin provides a workaround for printing specific HTML on macOS.

Prerequisites

• Minimum macOS version: 10.15. This is due to the use of PDFKit PDFDocument. Perhaps it can be substituted for NSDocument.

Example

<script lang="ts">
  import { onMount } from 'svelte';
  import { printDialog } from './path/to/your/module';

  let printableArea: HTMLElement;

  onMount(() => {
    printDialog(printableArea);
  });
</script>

<div bind:this={printableArea}>
  <h1>Hello, world!</h1>
  <p>This is some content that will be printed.</p>
</div>

How it Works

The goal is to get closer to the native print functionality of Safari that is missing by default in the tauri-apps/Wry crate.

1. Turn HTML into a base64: Using the jsPDF library, we can pass in any HTMLElement and have that produce a base64 string. Potentially discovering a similar method that is native to the WebKitWebView API. I'm tired and need to move forward with another project.
2. Send to Rust for binary conversion: Using the base64 crate to generate bytes that will load into the print window.

Other Goals

Currently, Silent printing is the only other specific printing feature that I've come across. It is possible to accomplish this in macOS with a derivative of the current implementation, but for Windows and Linux, I am less sure.
