高手请进：把纸张定义为三分之一高的241纸，当报表打印时，为什么会竖着打？

老兄，我也做过套打的程序，也是自定义纸张类型。当时用的也是MS VB6自带的那个变态的报表设计器，只要你的纸张类型不是标准的纸张(A4)类型，那打印进就是像你所说的竖向打印。我是用一些类，来实现打印的，且改变成了横向打印。源码如下：
1>orient.bas'------COMMENTS'For use on NT:
'  When adding a printer icon to the printer folder (when you double-
'  click on "Add Printer"), it is important to choose to save printer
'  settings on "My Computer" rather than on "Network Printer Server".
'  If "Network Printer Server" is used, then SetPrinter will fail
'  unless the user has privileges on the network printer server to
'  change the network server's global settings - in which case ALL
'  users of that printer are affected.  Whereas, when "My Computer"
'  is selected, the user only needs privileges on the local NT machine
'  and no one else is affected.'HP LaserJet 5si
'  As of 3/2/98,  The HP LaserJet 5si printer driver does not work
'  properly with the SetPrinter API call.  After using this code,
'  the 5si properties in the Printer folder are unaffected.
'  3/2/98  --  The current workaround is to use the HP 4si driver.

对呀，用水晶报表就好多了!
不好意思，因为CSDN最多只让连续发三次帖子，所以还没有说具体的调用方法：
老兄：不要怕麻烦，很简单的：你只要把以上两个类添加到你的工程中就OK了，也不要管看懂，还是看不懂!!说实话，我到现在还不完全懂呢!!!!(哈哈!)接下来，就是我的调用打印的一个按钮下的单击事件：(注意：还要加上一点：你必须在你的打印窗体上添加上一个listBox控件，这用来，列出你的机器上的所有按装的打印机。)**********************************************************************代码在下面：Private Sub cmdPrint_Click()
    '----------------------------------------------------------------------------默认打印机设置
    Dim osinfo As OSVERSIONINFO
    Dim retvalue As Integer
    osinfo.dwOSVersionInfoSize = 148
    osinfo.szCSDVersion = Space$(128)
    retvalue = GetVersionExA(osinfo)    If MsgBox("你确定已经把打印机的纸张更换了吗?", vbYesNo + vbExclamation, "警告") = vbNo Then
        Exit Sub
    End If
    '---------------------------------------------------------------------------设置纸张走向并打印
    Dim obj As pageset.PrinterControl
    On Error GoTo errorhandler:
        Set obj = New pageset.PrinterControl
        obj.ChngOrientationPortrait
        Dim i As Integer
        For i = 0 To List1.ListCount - 1
            If List1.List(i) = "打印报停单" Then
                List1.ListIndex = i
            End If
        Next i
        If osinfo.dwPlatformId = VER_PLATFORM_WIN32_WINDOWS Then
            Call Win95SetDefaultPrinter
        Else
        ' This assumes that future versions of Windows use the NT method
            Call WinNTSetDefaultPrinter
        End If
        STOP_RptSQL = "select autoid,a.mid,Tracffic_Card,AddToll_card1,AddToll_card2,Runing_card1,Runing_card2,car_card1," & _
                "car_card2,RoadStop_form,Stopdate_b,Stopdate_e,Maker,Make_Date,ZS_com,mcar_code,driver_name,car_name,car_kind " & _
                " from yz_stopinfo a inner join yz_carinfo b on a.mid=b.mid where autoid= '" & Trim(txt_AutoCode) & "'"
        Rpt_Stop.Show
        Rpt_Stop.PrintReport
        CmdPrint.Enabled = False
        Exit Sub
errorhandler:
          MsgBox Err.Description
          obj.ReSetOrientation

End Sub

最后，建议老兄以后做报表最好转到crystal report 或 active report!我现在就是用crystal report做报表! 而且，VB6自带的那个报表以后就从这个世界上消失了!
据听说，MS以后要推出一款非常值得期待的报表设计器!
祝：老兄好运，能解决当前问题!
