再在图片imgHead中心加字,当然字会变的。是从txtCustomer里取出来的
Private Sub PrintHead()
PrintPic imgHead, 0, lngPOSiITION_NowY
PrintFont Int_CONST_X * 4, lngPOSiITION_NowY + imgHead.Height * 0.8, frmCoil.txtCustomer, 16
PrintFont Int_CONST_X * 25.8, lngPOSiITION_NowY + imgHead.Height * 0.8, frmCoil.txtPlace, 16
End Sub'打印文字,同时预览和打印
Private Sub PrintFont(ByVal X As Integer, ByVal Y As Long, ByVal strPrint, ByVal intSize As Integer)
If intPrintOrView = 1 Then ‘预览
picPrint.CurrentX = intLeftStartX + X
picPrint.CurrentY = Y
picPrint.Font.Size = intSize
picPrint.Print strPrint
Else ’打印
Printer.CurrentX = intLeftStartX + X
Printer.CurrentY = Y
Printer.Font.Size = intSize
Printer.Print strPrint
End If
End Sub'打印图片,同时预览和打印
Private Sub PrintPic(ByVal ImgObject As Object, ByVal X As Integer, ByVal Y As Long)
If intPrintOrView = 1 Then
picPrint.PaintPicture ImgObject.Picture, intLeftStartX + X, Y, ImgObject.Width, ImgObject.Height
Else
Printer.PaintPicture ImgObject.Picture, intLeftStartX + X, Y, ImgObject.Width, ImgObject.Height
End If
End Sub我不知道有没有说清楚。
在pictrue控件上打印是正常的,但是打印机打出来后,就rt所说了

SetBkMode Printer.hdc, TRANSPARENT '=1
SetBkMode Printer.hdc, OPAQUE '=2
都不行?why?thks
