解决IE静默打印/保存PDF无弹窗问题

嘿，我之前也跟你一样碰到过IE打印弹窗的问题！你的代码里用ie.ExecWB 6, 2触发打印，虽然第二个参数2理论上是OLECMDEXECOPT_DONTPROMPTUSER（不提示用户），但IE的行为经常会受系统打印设置或者安全限制影响，导致弹窗还是会出来。下面给你两个靠谱的解决方案，分别对应静默打印和直接静默保存为PDF：

方案1：调整ExecWB参数并优化IE设置

首先，确保你的系统已经设置了默认打印机（如果是要输出PDF，就把Microsoft Print to PDF设为默认）。然后修改代码里的IE配置和打印参数，顺便禁用打印的页眉页脚，让输出更干净：

Sub View_Tech_Recalls_SilentPrint()
    Dim ie As Object
    Dim Recall_URL As String
    Dim TimeOutWebQuery As Integer
    Dim TimeOutTime As Date
    
    Set ie = CreateObject("InternetExplorer.Application")
    Recall_URL = Range("A1").Value
    
    ' 配置IE为静默模式，不需要显示界面
    ie.Navigate Recall_URL
    ie.StatusBar = False
    ie.Toolbar = False
    ie.Visible = False ' 直接隐藏IE，避免干扰
    ie.Resizable = True
    ie.AddressBar = False
    
    TimeOutWebQuery = 5
    TimeOutTime = DateAdd("s", TimeOutWebQuery, Now)
    
    ' 等待页面完全加载
    Do Until ie.ReadyState = 4
        DoEvents
        If Now > TimeOutTime Then
            ie.stop
            GoTo ErrorTimeOut
        End If
    Loop
    
    ' 额外等待几秒确保页面渲染完成（根据页面复杂度调整时长）
    Application.Wait (Now + TimeValue("0:00:03"))
    
    ' 可选：禁用打印的页眉页脚，避免默认的网址/日期输出
    ie.Document.execCommand("print", False, "<object ID='PrintSettings'><param name='MarginTop' value='0'><param name='MarginBottom' value='0'><param name='MarginLeft' value='0'><param name='MarginRight' value='0'><param name='Header' value=''><param name='Footer' value=''></object>")
    
    ' 执行静默打印：6是打印命令，2是不提示用户的执行选项
    ' 如果还是弹窗，可以试试把第二个参数改成1（默认执行）
    ie.ExecWB 6, 2
    
ErrorTimeOut:
    ' 关闭IE并释放资源
    ie.Quit
    Set ie = Nothing
End Sub

方案2：静默保存为PDF（更稳定，不依赖物理打印机）

如果你的核心需求是保存页面为PDF，直接用系统自带的Microsoft Print to PDF并通过Windows API自动操作“另存为”窗口会更可靠，完全不需要手动干预：

' 64位Office的API声明，32位Office请去掉PtrSafe，把LongPtr改成Long
Declare PtrSafe Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As LongPtr
Declare PtrSafe Function FindWindowEx Lib "user32" Alias "FindWindowExA" (ByVal hWnd1 As LongPtr, ByVal hWnd2 As LongPtr, ByVal lpsz1 As String, ByVal lpsz2 As String) As LongPtr
Declare PtrSafe Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hWnd As LongPtr, ByVal wMsg As Long, ByVal wParam As LongPtr, lParam As Any) As LongPtr
Declare PtrSafe Function SetForegroundWindow Lib "user32" (ByVal hWnd As LongPtr) As LongPtr

Const BM_CLICK = &HF5
Const WM_SETTEXT = &HC

Sub SaveAsPDF_Silent()
    Dim ie As Object
    Dim Recall_URL As String
    Dim TimeOutWebQuery As Integer
    Dim TimeOutTime As Date
    Dim savePath As String
    Dim hWnd As LongPtr, hWndChild As LongPtr
    
    ' 自定义PDF保存路径，这里用当前工作簿目录+时间戳命名
    savePath = ThisWorkbook.Path & "\TechRecall_" & Format(Now, "YYYYMMDD_HHMMSS") & ".pdf"
    
    Set ie = CreateObject("InternetExplorer.Application")
    Recall_URL = Range("A1").Value
    
    ie.Navigate Recall_URL
    ie.Visible = False ' 隐藏IE窗口
    
    TimeOutWebQuery = 5
    TimeOutTime = DateAdd("s", TimeOutWebQuery, Now)
    
    ' 等待页面加载完成
    Do Until ie.ReadyState = 4
        DoEvents
        If Now > TimeOutTime Then
            ie.stop
            GoTo ErrorTimeOut
        End If
    Loop
    
    ' 等待页面渲染
    Application.Wait (Now + TimeValue("0:00:03"))
    
    ' 触发打印对话框（选择Microsoft Print to PDF）
    ie.ExecWB 6, 1
    
    ' 等待"另存为"窗口弹出（根据系统速度调整等待时间）
    Application.Wait (Now + TimeValue("0:00:01"))
    
    ' 找到"另存为"窗口
    hWnd = FindWindow("#32770", "Save Print Output As")
    If hWnd <> 0 Then
        ' 找到文件名输入框
        hWndChild = FindWindowEx(hWnd, 0, "Edit", vbNullString)
        If hWndChild <> 0 Then
            ' 自动填写保存路径
            SendMessage hWndChild, WM_SETTEXT, 0, ByVal savePath
            ' 找到"保存"按钮并点击
            hWndChild = FindWindowEx(hWnd, 0, "Button", "&Save")
            If hWndChild <> 0 Then
                SetForegroundWindow hWnd
                SendMessage hWndChild, BM_CLICK, 0, 0
            End If
        End If
    End If
    
ErrorTimeOut:
    ie.Quit
    Set ie = Nothing
End Sub
