我实现标签打印的代码如下

但是现在发现一个问题 标签打出来是旋转了90度的  和我预想的不一样 代码改了很久一点作用也没有  请教高手

"条码"
Dim doc As New PrintDoc
doc.PageSetting.Width = 60
doc.PageSetting.Height = 40
Doc.PageSetting.LeftMargin = 1
Doc.PageSetting.TopMargin = 1

doc.Stacking = prt.StackingRulesEnum.InlineLeftToRight
Dim i As Integer=Tables("打印选择").Rows.count-1
For i=0 To i
    Dim t As Integer=Tables("打印选择").Rows(i)("打印张数")
    If t>0 Then
        For t=1 To t
            Dim ra As New prt.RenderArea

            ra.SplitHorzBehavior = prt.SplitBehaviorEnum.Never
            ra.SplitVertBehavior = prt.SplitBehaviorEnum.Never
            Doc.Body.ChildRen.Add(ra)
           
            rt = New prt.RenderText
            rt.Text = "名称: "
            rt.X =4
            rt.Y = 2
            rt.Style.Font = New Font("宋体",14)
            ra.Children.Add(rt)

自己顶一下

项目上传了 麻烦大家看看  试了下lin的方法 现在不旋转了 但是实际打印出来的页面占据了2张纸 而不是设想的一张纸

纸张大小60*40 prt.RenderArea大小58*38

问题已经解决 谢谢啦

我们在激光打印机和针式打印机下测试，都没有问题。

至于标签打印机，我们没有条件测试。

你调整调整纸张大小和边距看看，先简单的开始，打印几个简单的字符
