제목: API 개요printBase64
제목: printBase64base64로 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 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
printFile프린터 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 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’라는 제목의 섹션HTML 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 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>printPdf
인쇄 PDF를 위한 'printPdf' 섹션PDF 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__
- 웹: __CAPGO_KEEP_0__
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
printWebView웹 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 nameawait Printer.printWebView();
// Print with custom job nameawait Printer.printWebView({name: 'Dashboard Screenshot',});
// Use with print-specific CSS in your HTML// Add this to your app's CSS://타입 참조
