我在WPF中打印时遇到问题。在.Net 4.5中,它始终以纸张尺寸NorthAmericaLetter打印。在.Net Framework 3.5中,它使用我在Code中定义的正确纸张大小进行打印。我在相同的解决方案中使用相同的代码尝试了它,只是更改了目标框架。
我的问题是,我是否遗漏了PrintTicket配置中的内容或如何正确设置.Net 4.5中的纸张尺寸?
var visual = new DrawingVisual();
using (var context = visual.RenderOpen())
{
context.DrawRectangle(Brushes.CadetBlue, new Pen(Brushes.Black, 2),
new Rect(new Point(0, 0), new Size(793, 1122)));
context.DrawRectangle(Brushes.Brown, new Pen(Brushes.Black, 2),
new Rect(new Point(20, 20), new Size(40, 40)));
context.DrawRectangle(Brushes.Brown, new Pen(Brushes.Black, 2),
new Rect(new Point(20, 257), new Size(40, 40)));
}
var queue = new LocalPrintServer().DefaultPrintQueue;
queue.UserPrintTicket.PageMediaSize = queue
.GetPrintCapabilities()
.PageMediaSizeCapability
.Single(x => x.PageMediaSizeName == PageMediaSizeName.ISOA4);
queue.UserPrintTicket.PageOrientation = PageOrientation.Portrait;
var writer = PrintQueue.CreateXpsDocumentWriter(queue);
writer.Write(visual);

PageMediaSize pageMediaSize = new PageMediaSize(PageMediaSizeName.ISOA4);
if (printCapabilities.PageMediaSizeCapability.Contains(pageMediaSize))
{
PrintTicket deltaPrintTicket = new PrintTicket {PageMediaSize = pageMediaSize };
var result =
queue.MergeAndValidatePrintTicket(queue.UserPrintTicket,
deltaPrintTicket);
if (result.ValidatedPrintTicket.PageMediaSize == pageMediaSize)
{
queue.UserPrintTicket = result.ValidatedPrintTicket;
queue.Commit();
}
}
您必须合并并验证printticket:

也许是queue.Commit();不见了?
