Set up this Capacitor plugin in the project.
Use the package manager already used by the project.
Install these package(s): `@capgo/capacitor-printer`
Run the required Capacitor sync/update step after installation.
Read this markdown guide for the full setup steps: https://raw.githubusercontent.com/Cap-go/website/refs/heads/main/apps/docs/src/content/docs/docs/plugins/printer/getting-started.mdx
Use that guide for platform-specific steps, native file edits, permissions, config changes, imports, and usage setup.

제목 "API 개요"printBase64
제목 "printBase64"base64 형식으로 인코딩된 파일을 인쇄하기 위한 UI를 제공합니다.
플랫폼 동작:
- iOS: UIPrintInteractionController를 사용하여 base64 디코딩된 데이터를 사용합니다.
- Android: PrintManager를 사용하여 base64 디코딩된 데이터를 사용합니다.
- Web: base64 데이터를 blob으로 생성하고 인쇄 대화 상자를 열어줍니다.
성능 경고: 대용량 파일은 메모리 제약으로 인해 base64 디코딩 시 앱이 충돌할 수 있습니다. 5MB 이상의 파일은 printFile()을 사용하는 것을 권장합니다.
import { Printer } from '@capgo/capacitor-printer';
// Print a base64 encoded PDFawait Printer.printBase64({ name: 'Invoice #12345', data: 'base64-encoded-pdf-data', mimeType: 'application/pdf',});
// Print a base64 encoded imageawait Printer.printBase64({ name: 'Product Photo', data: '/9j/4AAQSkZJRgABAQEAYABgAAD/2wBDA...', mimeType: 'image/jpeg',});printFile
printFile파일을 출력하는 UI를 표시합니다.
플랫폼 동작:
- iOS: file URL을 사용하는 UIPrintInteractionController를 사용합니다. file:// 경로 또는 앱의 문서 폴더와 상대적인 경로를 지원합니다.
- Android: PrintManager를 사용하여 file path를 지원합니다. content:// URI 및 file:// 경로를 모두 지원합니다.
- Web: 파일을 읽고 출력 대화상자를 표시합니다.
지원하는 파일 형식:
- PDF 문서 (application/pdf)
- 이미지: JPEG, PNG, GIF, HEIC, HEIF
import { Printer } from '@capgo/capacitor-printer';
// iOS: Print from app documents directoryawait Printer.printFile({ name: 'Contract', path: 'file:///var/mobile/Containers/Data/Application/.../Documents/contract.pdf',});
// Android: Print from content URIawait Printer.printFile({ name: 'Receipt', path: 'content://com.android.providers.downloads.documents/document/123', mimeType: 'application/pdf',});
// Android: Print from file pathawait Printer.printFile({ name: 'Photo', path: 'file:///storage/emulated/0/Download/photo.jpg', mimeType: 'image/jpeg',});printHtml
‘printHtml’ 섹션HTML 문서를 인쇄하는 UI를 제공합니다.
플랫폼 동작:
- iOS: WKWebView에서 HTML을 렌더링하고 UIPrintInteractionController를 사용하여 인쇄합니다.
- Android: WebView에서 HTML을 렌더링하고 PrintManager를 사용하여 인쇄합니다.
- Web: iframe에 HTML 콘텐츠를 삽입하고 인쇄 대화 상자를 트리거합니다.
HTML Requirements:
- 완전한 HTML 문서 구조가 포함되어야 합니다.
- 인라인 CSS 스타일 또는 스타일 태그를 포함할 수 있습니다.
- 외부 자원 (이미지, 스타일 시트)에는 절대 URL을 사용해야 합니다.
- 인쇄 전용 CSS를 사용하여
import { Printer } from '@capgo/capacitor-printer';
// Simple HTML documentawait Printer.printHtml({name: 'Sales Report',html: '<html><body><h1>Q4 Sales Report</h1><p>Revenue: $125,000</p></body></html>',});
// HTML with print-specific CSSawait Printer.printHtml({name: 'Styled Invoice',html: `<html><head><style>플랫폼 동작:
iOS
- : UIPrintInteractionController를 사용하여 PDF 파일 URL을 사용합니다.Android
- __CAPGO_KEEP_0__: __CAPGO_KEEP_0__을 사용합니다.
- 웹: 객체 URL을 생성하고 프린트 대화상자를 열어줍니다.
파일 경로 요구 사항:
- iOS: 앱의 문서 폴더와 상대 경로만 지원합니다.
- Android: 다운로드, 미디어 스토어에서 가져온 콘텐츠:// URI 또는 file:// 경로를 지원합니다.
- 웹: 액세스 가능한 파일 경로만 지원합니다.
import { Printer } from '@capgo/capacitor-printer';
// Print PDF from app storageawait Printer.printPdf({ name: 'Annual Report 2024', path: 'file:///var/mobile/Containers/Data/Application/.../Documents/report.pdf',});
// Print PDF from Android downloadsawait Printer.printPdf({ name: 'Downloaded Document', path: 'content://com.android.providers.downloads.documents/document/123',});printWebView
프린트 웹 뷰웹 뷰 콘텐츠를 인쇄하는 UI를 표시합니다.
앱의 웹 뷰에서 현재 표시 중인 콘텐츠를 인쇄합니다.
플랫폼 동작:
- iOS: WKWebView의 view가 인쇄 가능할 때 UIPrintInteractionController를 사용합니다.
- Android: WebView.createPrintDocumentAdapter()를 사용하여 PrintManager와 함께 인쇄합니다.
- Web: 현재 페이지에 대해 window.print()를 트리거합니다.
인쇄 스타일: CSS 인쇄 미디어 쿼리 지원을 위해 커스터마이즈할 수 있습니다. 웹 뷰의 현재 스타일이 적용됩니다.
