针对VB打印的一些常用设置

我们平时在做票据打印的时候常常遇到如何设置纸张，默认大小，边距等问题。拼命的到处提问，搜索，以下代码就可以帮助你解决部分问题。

1、调用API函数设置打印的方向

'Constants used in the DevMode structure
Private Const CCHDEVICENAME = 32
Private Const CCHFORMNAME = 32

'Constants for NT security
Private Const STANDARD_RIGHTS_REQUIRED = &HF0000

Private Const PRINTER_ACCESS_USE = &H8
Private Const PRINTER_ALL_ACCESS = (STANDARD_RIGHTS_REQUIRED Or PRINTER_ACCESS_ADMINISTER Or PRINTER_ACCESS_USE)

'Constants used to make changes to the values contained in the DevMode
Private Const DM_MODIFY = 8
Private Const DM_IN_BUFFER = DM_MODIFY
Private Const DM_COPY = 2
Private Const DM_OUT_BUFFER = DM_COPY
Private Const DM_DUPLEX = &H1000&
Private Const DMDUP_SIMPLEX = 1
Private Const DMDUP_VERTICAL = 2
Private Const DMDUP_HORIZONTAL = 3
Private Const DM_ORIENTATION = &H1&
Private PageDirection As Integer
'------USER DEFINED TYPES

'The DevMode structure contains printing parameters.
'Note that this only represents the PUBLIC portion of the DevMode.
' The full DevMode also contains a variable length PRIVATE section
' which varies in length and content between printer drivers.
'NEVER use this User Defined Type directly with any API call.
' Always combine it into a FULL DevMode structure and then send the
' full DevMode to the API call.
Private Type DEVMODE

3、判断某个纸张类型是否存在

以上代码有，修改一下既可

4、默认某个纸张

Private Const CCHDEVICENAME = 32
Private Const CCHFORMNAME = 32
Private Type DEVMODE
dmDeviceName As String * CCHDEVICENAME
dmSpecVersion As Integer
dmDriverVersion As Integer
dmSize As Integer
dmDriverExtra As Integer
dmFields As Long
dmOrientation As Integer
dmPaperSize As Integer
dmPaperLength As Integer
dmPaperWidth As Integer
dmScale As Integer
dmCopies As Integer
dmDefaultSource As Integer
dmPrintQuality As Integer
dmColor As Integer
dmDuplex As Integer
dmYResolution As Integer
dmTTOption As Integer
dmCollate As Integer
dmFormName As String * CCHFORMNAME
dmUnusedPadding As Integer
dmBitsPerPel As Long
dmPelsWidth As Long
dmPelsHeight As Long
dmDisplayFlags As Long
dmDisplayFrequency As Long
End Type

Private Type PRINTER_DEFAULTS
pDatatype As String
pDevMode As DEVMODE
DesiredAccess As Long
End Type

Private Declare Function OpenPrinter Lib "winspool.drv" Alias "OpenPrinterA" (ByVal pPrinterName As String, phPrinter As Long, pDefault As PRINTER_DEFAULTS) As Long
Private Declare Function GetPrinter Lib "winspool.drv" Alias "GetPrinterA" (ByVal hPrinter As Long, ByVal Level As Long, buffer As Any, ByVal pbSize As Long, pbSizeNeeded As Long) As Long

Private Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" (Destination As Any, Source As Any, ByVal Length As Long)
Private Declare Function SetPrinter Lib "winspool.drv" Alias "SetPrinterA" (ByVal hPrinter As Long, ByVal Level As Long, pPrinter As Any, ByVal Command As Long) As Long

Public Sub SetPrintDefault(ByVal FormName As String, PaperSize As Integer)
Dim SizeNeeded As Long, buffer() As Long
Dim pDef As PRINTER_DEFAULTS
Dim X As DEVMODE
Dim lret As Long
Dim mhPrinter As Long
Dim str As String

pDef.DesiredAccess = PRINTER_ALL_ACCESS
lret = OpenPrinter(Printer.DeviceName, mhPrinter, pDef)

ReDim Preserve buffer(0 To 0)

lret = GetPrinter(mhPrinter, 9, buffer(0), 0, SizeNeeded)

ReDim Preserve buffer(0 To (SizeNeeded / 4) + 3) As Long

ClosePrinter mhPrinter

End Sub

'调用------------------
'GetFormNum(FormName) 这个是纸张的序号
SetPrintDefault "MyCustomForm", GetFormNum(FormName)

5、如何删除一个纸张类型

'函数名：DeleteCustomPrintSetting(FormName As String)
'
'参 数：FormName 选择纸张类型的名称
'
'功 能：定义纸张的类型
Private Sub DeleteCustomPrintSetting(FormName As String)

Dim RetVal As Long
Dim PrinterHandle As Long ' Handle to printer
Dim PrinterName As String
Dim Continue As Long

' Delete form that is selected in ListBox.
PrinterName = Printer.DeviceName ' Current printer
If OpenPrinter(PrinterName, PrinterHandle, 0&) Then

On Error GoTo ListBoxERR ' Trap for no selection.
RetVal = DeleteForm(PrinterHandle, FormName & Chr(0))
If RetVal <> 0 Then ' DeleteForm succeeded.
' MsgBox FormName & " deleted!", vbInformation, "Success!"
Else
' MsgBox FormName & " not deleted!" & vbCrLf & vbCrLf & _
"Error code: " & Err.LastDllError, vbInformation, "Failure!"
End If
ClosePrinter (PrinterHandle)
End If

Exit Sub
ListBoxERR:
MsgBox "Select a printer from the ListBox before using this option.", _
vbExclamation
ClosePrinter (PrinterHandle)

End Sub

以上为个人的总结，部分代码摘录于网上，本人只用VB两个星期，有错误指出敬请原谅。
在98的打印设置，在之前的一篇文章有写，可以去查看一下作为参考。

另外给点个人建议，设置纸张大小的时候，最好比原纸张大一点，由于每个打印机对于这些设置都有不同的变化，打印纸张必须在打印机的打印大小的允许范围内，否则就会出错，对于网络打印机是无法新建自定义纸张类型（没测试过）

8888 希望大家别碰上我遇到那样的问题。就是在一台打印机上做出了自己的纸张类型，但是打印不完全，其次在其他打印机上是正常的，，晕倒~~~~~
