分享送分400分：请问如何在打印预览前由程序选定自定义纸张
VB6+DATAREPORT开发的程序，在打印预览前，DATAREPORT默认是使用默认打印机的各项设置。
现在的问题是：我打印时需要一个自定义的纸张规格，但是此自定义纸张在打印服务器中设置了之后，但在打印机的打印首选项的纸张规格列表中却没有显示。打印机是针式打印机，自定义纸张是18X9.5CM，完全在这个打印机的可打范围之内。
所以我想问一下，在打印预览前，如由程序控制选取的我的自定纸张。
有能帮我解决的，我会再开贴，别外送那300分。谢谢大家。

中国的程序员，在编程的时候，就好像是在操作一个有几千个控制按钮的机器，而这些个按钮还只有其中一小部分，我们知道是什么作用，更不要说了解这个机器的原理了，真是悲哀。

这样啊。其实里面最难的是一些API ，这个就不要注释了，还是你自己具体查一下是什么意思更好。
至于那个结构体，最好还是有人给注释一下~

调用printer对象设置纸张规格。在公共模块里加入这个，然后调用。注意红色部分
Option Explicit
Public Enum PrinterOrientationConstants
OrientPortrait = 1
OrientLandscape = 2
End Enum
Private Type DEVMODE
dmDeviceName As S……

怎么到底粘贴的都是这段代码，一字不差。
请详细注解一下以下这些代码，每一句都请注释一下，各函数的各个参数请详细注解，在哪儿调用自定义纸张类型：
Call GetPrinter(hPrinter, 2&, 0&, 0&, nSize)
ReDim bPrinterInfo2(1 To nSize) As Byte
lResult = GetPrinter(hPrinter, 2, bPrinterInfo2(1), nSize, nSize)
Call CopyMemory(pi2, bPrinterInfo2(1), Len(pi2))
nSize = DocumentProperties(0&, hPrinter, sPrnName, 0&, 0&, 0)
ReDim bDevMode(1 To nSize)
If pi2.pDevMode Then
Call CopyMemory(bDevMode(1), ByVal pi2.pDevMode, Len(dm))
Else
Call DocumentProperties(0&, hPrinter, sPrnName, bDevMode(1), 0&, DM_OUT_BUFFER)
End If
Call CopyMemory(dm, bDevMode(1), Len(dm))
Call CopyMemory(olddm, bDevMode(1), Len(olddm))

' .dmPaperLength = iDmpaperLength

lResult = SetPrinter(hPrinter, 2, pi2, 0&)
Call ClosePrinter(hPrinter)

请帮我看一下，Veron_04，您所说的代码应加在何处，如何把CommanDialog.ShowPrinter 接收到的信息传给DATAREPORT3.
谢谢。

使用CommanDialog.ShowPrinter，会打开一个打印对话框，里面可以设置页面等属性。
