Question

我尝试动态创建并静默打印文档。问题是我需要缩放文档以适应页面。我尝试使用PrintTicket.PageScalingFactor但它不起作用：当打印机打印文档时，PageScalingFactor = 50和PageScalingFactor = 250之间没有区别。 PageScalingFactor不会影响任何内容。这是一段代码片段：创建PrintTickets：

PrintTicket tkt = new PrintTicket();

tkt.Collation = Collation.Uncollated;
tkt.CopyCount = 1;
tkt.DeviceFontSubstitution = DeviceFontSubstitution.On;
tkt.Duplexing = Duplexing.OneSided;
tkt.InputBin = InputBin.AutoSelect;
tkt.OutputColor = OutputColor.Monochrome;
tkt.PageMediaSize = new PageMediaSize(PageMediaSizeName.ISOA9);
tkt.PageMediaType = PageMediaType.Unknown;
tkt.PageOrder = PageOrder.Standard;
tkt.PageOrientation = PageOrientation.Portrait;
tkt.PageResolution = new PageResolution(PageQualitativeResolution.Draft);
tkt.PageScalingFactor = 40;
tkt.PagesPerSheet = 1;
tkt.TrueTypeFontMode = TrueTypeFontMode.DownloadAsOutlineFont;


StackPanel myPanel = new StackPanel();
myPanel.Margin = new Thickness(15);

设置PrintQueue并使用数据填充StackPanel无关紧要印刷：

myPanel.Measure(new Size(dialog.PrintableAreaWidth,
                         dialog.PrintableAreaHeight));
myPanel.Arrange(new Rect(new Point(0, 0),
                myPanel.DesiredSize));

dial2.PrintVisual(myPanel, "A Great Image.");

我设置PageScalingFactor 40,100,250 - 输出是一样的。我该怎么办？

Answer 1

PageScaling功能是否设置为CustomSquare？

为什么PageScalingFactor不会影响任何东西？
