Question

如果有人可以提供帮助，我有两个问题。我是VBA的新手。我的excel表上有一个命令打印按钮，我添加了下面列出的代码。当我点击打印按钮时，我将第一页打印两次，但其余页面打印单个，这就是我想要的。如何修复代码，使其只打印一次。另一件事是打印管理器窗口打开我选择打印机，我想让代码选择单页打印而不是双面打印。打印机默认设置设置为双面打印，我不想通过窗口更改该设置，但代码可以自动选择单面打印。

谢谢，

Private Sub PrintAll_Click()

    Dim rngOffenders As Range
    Set rngOffenders = Worksheets("Names").Range("A2", Worksheets("Names").Range("A2").End(xlDown))

    Dim willPrint As Boolean
        willPrint = Application.Dialogs(xlDialogPrint).Show
        If Not willPrint Then Exit Sub

    Dim rng As Range
        For Each rng In rngOffenders.Cells
        Worksheets("Template").Range("LastName").Value = rng.Value
        Calculate
        Worksheets("Template").PrintOut
    Next rng

End Sub

Answer 1

关于重复打印，我的猜测是，在没有测试的情况下，通过Show打印对话框，一旦按下“确定”，就会对第一张/活动页面调用打印。然后，当您遍历rngOffenders.Cells时，您将再次打印该表。因此，您可以从rngOffenders中的第二个单元格开始，以避免这种情况。

Dim i As Long
For i = 2 To rngOffenders.Cells.Count
    Worksheets("Template").Range("LastName").Value = rngOffenders.Cells(i).Value
    Calculate
    Worksheets("Template").PrintOut
Next rng

对于打印机设置，这更复杂。见here：

执行此操作的最佳方法是使用API调用。下面的文章为您提供了一个VB代码示例：

Q230743

此代码只有一个“问题”：它是为VB编写的，并使用Printer.DeviceName返回当前所选打印机的名称。在Word VBA中，您需要使用ActivePrinter替换它。问题是这些命令返回的字符串略有不同，即使它们都从控制面板中指定的名称获取打印机的名称。打印机。例如。：

ActivePrinter： LPT1上的HP LaserJet 6L PCL：

Printer.DeviceName： HP LaserJet 6L PCL

因此，您需要相应地测试和修改代码示例。

但是，如果您不想使用API调用，则可以安装具有双工属性集的重复打印机驱动程序并打印到该驱动程序（通过更改ActivePrinter）。

链接的知识库文章（最后）演示如何将打印机设置为双面打印。大多数相同的代码应该用于逆操作，你只需要弄清楚该属性传递的值。

测试程序：

将其放入标准模块中。请注意可能需要调整打印机字符串的长度（删除端口组件，例如“HP Ink Jet Fantastico on LP02 ”等）

Option Explicit
Sub test()

    Dim pName As String
    pName = ActivePrinter
    ' Note you may need to adjust this value to remove the port string component
    pName = Left(pName, (Len(pName) - 9))

    SetPrinterDuplex pName, 1  '1 = NOT duplex printing.

    'Here you might want to actually print something, for example:
    Worksheets("Template").PrintOut

End Sub

在单独的模块中，放置所有与打印机相关的代码。注意：我在没有打印机访问权限的计算机上，因此我无法测试或进一步调试此解决方案。

Answer 2

您可以像这样打印第一页：

Dim i As Long, k As Long
Dim lpc As Long

lpc = ActiveSheet.HPageBreaks.Count

 For i = 1 To lpc + 1
    If i = 1 Then
    k = 2
    Else
    k = 1
    End If
ActiveSheet.PrintOut from:=i, To:=i, Copies:=k
 Next

命令打印按钮。当我点击打印按钮时，第一页打印两次其他页面打印单个，这就是我想要的
