base64로 인코딩된 파일을 인쇄하는 UI를 제공합니다.

플랫폼 동작:

  • iOS: UIPrintInteractionController를 사용하여 base64 디코딩된 데이터를 사용합니다.
  • Android: PrintManager를 사용하여 base64 디코딩된 데이터를 사용합니다.
  • Web: base64 데이터에서 블록을 생성하고 프린트 대화상자를 열어줍니다.

성능 경고: 대형 파일은 메모리 제한으로 인해 base64 디코딩을 통해 앱이 충돌할 수 있습니다. 5MB 이상의 파일을 사용하는 경우 printFile() 대신 사용하는 것을 권장합니다.

import { Printer } from '@capgo/capacitor-printer';
// Print a base64 encoded PDF
await Printer.printBase64({
name: 'Invoice #12345',
data: 'base64-encoded-pdf-data',
mimeType: 'application/pdf',
});
// Print a base64 encoded image
await Printer.printBase64({
name: 'Product Photo',
data: '/9j/4AAQSkZJRgABAQEAYABgAAD/2wBDA...',
mimeType: 'image/jpeg',
});

printFile

printFile

프린터 장치 파일을 프린트하기 위해 프린팅 UI를 표시합니다.

플랫폼 동작:

  • iOS: 파일 URL을 사용하는 UIPrintInteractionController를 사용합니다. 앱의 문서 폴더와 상대 경로를 지원하는 file:// 경로를 사용합니다.
  • Android: PrintManager를 사용하여 파일 경로를 사용합니다. content:// URI와 file:// 경로를 모두 지원합니다.
  • Web: 파일을 읽고 프린트 대화 상자를 열어줍니다.

지원하는 파일 형식:

  • PDF 문서 (application/pdf)
  • 이미지: JPEG, PNG, GIF, HEIC, HEIF
import { Printer } from '@capgo/capacitor-printer';
// iOS: Print from app documents directory
await Printer.printFile({
name: 'Contract',
path: 'file:///var/mobile/Containers/Data/Application/.../Documents/contract.pdf',
});
// Android: Print from content URI
await Printer.printFile({
name: 'Receipt',
path: 'content://com.android.providers.downloads.documents/document/123',
mimeType: 'application/pdf',
});
// Android: Print from file path
await Printer.printFile({
name: 'Photo',
path: 'file:///storage/emulated/0/Download/photo.jpg',
mimeType: 'image/jpeg',
});

HTML 문서를 인쇄하기 위한 인쇄 UI를 제공합니다.

플랫폼 동작:

  • iOS: WKWebView에서 HTML을 렌더링하고 UIPrintInteractionController를 사용하여 인쇄합니다.
  • Android: WebView에서 HTML을 렌더링하고 PrintManager를 사용하여 인쇄합니다.
  • Web: iframe에 HTML 콘텐츠를 생성하고 인쇄 대화상자를 트리거합니다.

HTML 요구 사항:

  • 완전한 HTML 문서 구조를 포함해야 합니다.
  • 인라인 CSS 스타일 또는 스타일 태그를 포함할 수 있습니다.
  • 외부 자원 (이미지, 스타일 시트)에는 절대 URL을 사용해야 합니다.
  • 인쇄 전용 CSS가 추가될 수 있습니다.
import { Printer } from '@capgo/capacitor-printer';
// Simple HTML document
await Printer.printHtml({
name: 'Sales Report',
html: '<html><body><h1>Q4 Sales Report</h1><p>Revenue: $125,000</p></body></html>',
});
// HTML with print-specific CSS
await Printer.printHtml({
name: 'Styled Invoice',
html: `
<html>
<head>
<style>

PDF 문서를 인쇄하기 위한 인쇄 UI를 제공합니다.

플랫폼 동작:

  • iOS: PDF 파일 URL을 사용하여 UIPrintInteractionController를 사용합니다.
  • Android: PdfDocument을 사용하여 PrintManager를 사용합니다.
  • Web: 인쇄 대화 상자를 열기 위해 객체 URL을 생성합니다.

파일 경로 요구 사항:

  • iOS: __CAPGO_KEEP_0__
  • 안드로이드: __CAPGO_KEEP_0__
  • : __CAPGO_KEEP_0__
import { Printer } from '@capgo/capacitor-printer';
// Print PDF from app storage
await Printer.printPdf({
name: 'Annual Report 2024',
path: 'file:///var/mobile/Containers/Data/Application/.../Documents/report.pdf',
});
// Print PDF from Android downloads
await Printer.printPdf({
name: 'Downloaded Document',
path: 'content://com.android.providers.downloads.documents/document/123',
});

printWebView

printWebView

웹 뷰 콘텐츠를 출력하기 위한 UI를 제공합니다.

앱 내의 현재 웹 뷰 콘텐츠를 출력합니다.

플랫폼 동작:

  • iOS: WKWebView의 view가 인쇄 가능할 때 UIPrintInteractionController를 사용합니다.
  • Android: WebView.createPrintDocumentAdapter()를 사용하여 PrintManager와 함께 인쇄합니다.
  • Web: 현재 페이지의 window.print()를 트리거합니다.

인쇄 스타일: 인쇄 미디어 쿼리(CSS)를 사용하여 인쇄를 커스터마이즈합니다. 웹 뷰의 현재 스타일이 적용됩니다.

import { Printer } from '@capgo/capacitor-printer';
// Print current web view with default name
await Printer.printWebView();
// Print with custom job name
await Printer.printWebView({
name: 'Dashboard Screenshot',
});
// Use with print-specific CSS in your HTML
// Add this to your app's CSS:
//

PrintBase64Options

인쇄 Base64 옵션

Base64 인코딩된 데이터를 인쇄하는 옵션입니다.

export interface PrintBase64Options extends PrintOptions {
/**
* Valid base64 encoded string representing the file content.
*
* The base64 string should NOT include the data URL prefix (e.g., "data:application/pdf;base64,").
* Only provide the raw base64 encoded content.
*
* **Performance Considerations:**
* - Base64 encoding increases data size by approximately 33%
* - Large files (>5MB) may cause memory issues when decoding
* - Consider using printFile() for large documents
*
* **Platform Notes:**
* - **iOS**: Decoded to NSData and passed to UIPrintInteractionController
* - **Android**: Decoded to byte array and written to temporary file
* - **Web**: Converted to Blob for printing
*
* @since 7.0.0
* @example 'base64-encoded-pdf-data'
*/
data: string;
/**
* MIME type of the base64 encoded data.
*
* **Supported types:**
* - `application/pdf` - PDF documents
* - `image/jpeg` - JPEG images
* - `image/.png` - PNG images
* - `image/.gif` - GIF images (iOS/Android only)
* - `image/heic` - HEIC images (iOS only)
* - `image/heif` - HEIF images (iOS only)
*
* **Platform Support:**
* - All platforms support PDF, JPEG, and PNG
* - GIF support varies by platform
* - HEIC/HEIF are iOS-specific formats
