我发现生成具有良好图像质量的 pdf 文件的唯一方法是使用 pdf 打印机,因为“另存为 pdf”似乎总是压缩图像。Win 10 有一个内置打印机(“Microsoft Print to PDF”),在 Win 7 中你需要安装一个额外的打印机,我不确定你是否可以以同样的方式访问所有内容(可能是插件添加的一种更简单的方法)。
当然,您可以使用以下命令对所有内容进行硬编码:
' "Application.ActivePrinter = " sets Word's default printer (not Windows'!), so save the old setting, then restore it in the end
Dim newPrinter as String
Dim oldPrinter as String
newPrinter = "Microsoft Print to PDF"
oldPrinter = Application.ActivePrinter
ActivePrinter = newPrinter
ActiveDocument.PrintOut OutputFileName:=filepathandname + ".pdf"
Application.ActivePrinter = oldPrinter
...但是如果打印机不存在,您将收到一条错误消息,因此获取所有可用打印机的列表会更安全,然后检查硬编码名称。
使用 Access ( click )这很容易,不幸的是 Word 的 VBA 无法访问Printers
or Printer
,这使一切变得更加复杂:
这里有一个很好的解决方案,但它只有在您使用的是 32 位的旧版 Word 时才有效。Word 2019 默认为 64 位,这会引发错误消息,我还没有设法让该代码以 64 位运行(此处的建议并未修复它)。
相反,我现在使用这个版本来检查已安装打印机的注册表,并且更容易更新以使用 64 位。
调用额外的模块:
Private Function PrinterExists() As Boolean
Dim allprinters() As String
Dim foundPrinterVar As Variant
Dim foundPrinter As String
Dim printerName As String
printerName = "Microsoft Print to PDF"
PrinterExists = False
allprinters = GetPrinterFullNames()
For Each foundPrinterVar In allprinters
foundPrinter = CStr(foundPrinterVar) 'Convert Variant to String
If foundPrinter = printerName Then
PrinterExists = True
Exit Function
End If
Next
End Function
用于检查可同时使用 32 位和 64 位的打印机的代码(来源:单击,由我更改):
