本章将系统讲解打印设置与配置、打印预览、多页面打印控制、打印机选择与管理、批量打印处理,以及打印质量优化,同时提供完整的综合示例代码,帮助你快速实现高效打印。
打印设置是控制打印输出效果和布局的关键,包括:
Aspose.Words 提供了 PrintOptions
类,可以配置文档打印属性,支持丰富的自定义选项。
using Aspose.Words;
using System.Drawing.Printing;
class PrintSettingsExample
{
static void Main()
{
Document doc = new Document("SampleDocument.docx");
PrintOptions printOptions = new PrintOptions
{
// 设置纸张方向
Orientation = PrintOrientation.Landscape,
// 设置打印页范围
PageRange = "1-5",
// 设置打印份数
Copies = 2,
// 启用双面打印
Duplex = Duplex.Vertical
};
// 打印到默认打印机
doc.Print(printOptions);
Console.WriteLine("打印任务已提交。");
}
}
Orientation
控制横向或纵向打印PageRange
支持单页、范围页、逗号分隔页等Duplex
控制单双面打印打印预览是用户在实际打印前检查文档布局和效果的关键步骤。Aspose.Words 提供了生成图像或 PDF 预览的方式:
using Aspose.Words;
using Aspose.Words.Saving;
class PrintPreviewExample
{
static void Main()
{
Document doc = new Document("SampleDocument.docx");
// 将文档每页保存为图像
ImageSaveOptions options = new ImageSaveOptions(SaveFormat.Png)
{
PageCount = doc.PageCount,
PageIndex = 0
};
for (int i = 0; i < doc.PageCount; i++)
{
options.PageIndex = i;
doc.Save($"Preview_Page_{i + 1}.png", options);
}
Console.WriteLine("打印预览图像生成完成。");
}
}
ImageSaveOptions
可生成分页图像大型文档通常需要打印特定页或分批打印:
using Aspose.Words;
using System.Drawing.Printing;
class MultiPagePrintExample
{
static void Main()
{
Document doc = new Document("SampleDocument.docx");
PrintOptions printOptions = new PrintOptions
{
PageRange = "1-3,5,7-10", // 打印页范围
Copies = 1
};
doc.Print(printOptions);
Console.WriteLine("多页面打印完成。");
}
}
Aspose.Words 支持指定打印机打印,实现多打印机环境管理:
using Aspose.Words;
using System.Drawing.Printing;
class PrinterSelectionExample
{
static void Main()
{
Document doc = new Document("SampleDocument.docx");
// 获取本机打印机列表
foreach (string printer in PrinterSettings.InstalledPrinters)
{
Console.WriteLine($"可用打印机: {printer}");
}
PrintOptions printOptions = new PrintOptions
{
PrinterName = "Microsoft Print to PDF"
};
doc.Print(printOptions);
Console.WriteLine("已打印到指定打印机。");
}
}
PrinterSettings.InstalledPrinters
获取系统打印机PrinterName
指定打印机,确保打印任务发送到正确设备企业环境中,文档通常需要批量打印:
using Aspose.Words;
using System;
using System.IO;
class BatchPrintExample
{
static void Main()
{
string folderPath = @"C:\Documents\ToPrint";
string[] files = Directory.GetFiles(folderPath, "*.docx");
foreach (string file in files)
{
Document doc = new Document(file);
doc.Print(); // 使用默认打印机
Console.WriteLine($"已打印文档: {Path.GetFileName(file)}");
}
Console.WriteLine("批量打印完成。");
}
}
Directory.GetFiles
批量处理文档打印质量优化涉及:
using Aspose.Words;
using Aspose.Words.Saving;
class PrintQualityExample
{
static void Main()
{
Document doc = new Document("SampleDocument.docx");
ImageSaveOptions options = new ImageSaveOptions(SaveFormat.Png)
{
Resolution = 300, // 提高图像分辨率
UseHighQualityRendering = true
};
doc.Save("HighQualityPreview.png", options);
Console.WriteLine("打印质量优化完成。");
}
}
Resolution
控制输出 DPIUseHighQualityRendering
保证图像清晰using Aspose.Words;
using Aspose.Words.Saving;
using System;
using System.Drawing.Printing;
using System.IO;
class CompletePrintWorkflow
{
static void Main()
{
string[] documents = Directory.GetFiles(@"C:\Documents\ToPrint", "*.docx");
foreach (string docPath in documents)
{
Document doc = new Document(docPath);
// 打印设置
PrintOptions printOptions = new PrintOptions
{
Orientation = PrintOrientation.Portrait,
PageRange = "1-5",
Copies = 1,
Duplex = Duplex.Vertical,
PrinterName = "Microsoft Print to PDF"
};
// 打印预览生成
ImageSaveOptions previewOptions = new ImageSaveOptions(SaveFormat.Png)
{
Resolution = 300,
UseHighQualityRendering = true
};
for (int i = 0; i < doc.PageCount; i++)
{
previewOptions.PageIndex = i;
doc.Save($"Preview_{Path.GetFileNameWithoutExtension(docPath)}_Page{i + 1}.png", previewOptions);
}
// 打印文档
doc.Print(printOptions);
Console.WriteLine($"已打印文档: {Path.GetFileName(docPath)}");
}
Console.WriteLine("完整打印流程完成!");
}
}
