WPF 프로젝트 생성

dotnet new wpf -n WpfPrintSolution
cd WpfPrintSolution

필요 어셈블리 참조 추가

• System.Printing (프린터 관리)
• PresentationFramework (UI 컨트롤)

핵심 기능 구현 (MainWindow.xaml.cs)

using System;
using System.Printing;
using System.Windows;
using System.Windows.Documents;

namespace WpfPrintSolution
{
    public partial class MainWindow : Window
    {
        private PrintDialog printDialog;
        private PrintQueue activePrinter;

        public MainWindow()
        {
            InitializeComponent();
            SetupPrinter();
        }

        private void SetupPrinter()
        {
            printDialog = new PrintDialog();
            printDialog.PrintTicket.PageOrientation = PageOrientation.Portrait;
            printDialog.PrintTicket.PageMediaSize = PageMediaSize.ISOA4;
        }

        private void ShowPreview(object sender, RoutedEventArgs e)
        {
            if (printDialog.ShowDialog() == true)
            {
                printDialog.PrintDocument(
                    DocumentContent.DocumentPaginator, 
                    "문서 미리보기"
                );
            }
        }

        private void ExecutePrint(object sender, RoutedEventArgs e)
        {
            try
            {
                if (activePrinter == null)
                    throw new InvalidOperationException("프린터를 선택하세요");
                
                var documentWriter = PrintQueue.CreateXpsDocumentWriter(activePrinter);
                documentWriter.Write(DocumentContent);
                MessageBox.Show("인쇄 작업 시작됨");
            }
            catch (Exception ex)
            {
                MessageBox.Show($"오류 발생: {ex.Message}");
            }
        }

        private void PickPrinter(object sender, RoutedEventArgs e)
        {
            PrintServer server = new PrintServer();
            var availablePrinters = server.GetPrintQueues();
            
            printDialog = new PrintDialog();
            printDialog.PrintQueue = availablePrinters
                .FirstOrDefault(p => p.Name.Contains("Samsung")); 
            activePrinter = printDialog.PrintQueue;
        }
    }
}

주요 기능 설명

인쇄 설정 구성

printDialog.PrintTicket.PageOrientation = PageOrientation.Landscape;
printDialog.PrintTicket.PageMediaSize = PageMediaSize.ISOA5;
printDialog.PrintTicket.CopyCount = 3;

동적 콘텐츠 생성

var newSection = new Paragraph();
newSection.Inlines.Add(new Run("실시간 생성된 텍스트"));
DocumentContent.Blocks.Add(newSection);

프린터 필터링

var printers = new PrintServer().GetPrintQueues();
var target = printers.FirstOrDefault(p => p.Name.Contains("Canon"));

고급 기능

이미지 인쇄

var printImage = new Image {
    Source = new BitmapImage(new Uri("image.png", UriKind.Relative)),
    Width = 300,
    Height = 150
};
DocumentContent.Blocks.Add(new Paragraph(printImage));

인쇄 작업 모니터링

var job = activePrinter.AddJob("DocumentJob");
job.Start();
job.End();

배포 요구사항

• System.Printing 어셈블리 포함
• 앱 매니페스트 설정:

  <requestedExecutionLevel level="asInvoker" uiAccess="false" />

• 타겟 프린터 드라이버 사전 설치
