Webbrowser is a browser control built in IE, which does not need to be downloaded by users.

I. webbrowser Control
<Object ID = 'webbrowser 'width = 0 Height = 0 classid = 'clsid: 8856f961-340a-11d0-a96b-00c04fd705a2 '> </Object>
2. webbrowder Control Method
// Print

Webbrowser1.execwb (6, 1 );

// Print settings

Webbrowser1.execwb (8, 1 );

// Print and preview

Webbrowser1.execwb (7,1 );

There are other usage examples of this component:
Webbrowser. execwb () Open
Web. execwb () Close all existing IE Windows and open a new window
Web. execwb () save Web Page
Web. execwb (6, 1) Printing
Web. execwb (7,1) print and preview
Web. execwb (8, 1) Printing page settings
Web. execwb () view page properties
Web. execwb () seems to be undo, to be confirmed
Select all web. execwb ()
Web. execwb (22, 1) Refresh
Web. execwb () Close form no prompt
However, printing prints the entire page, and prints out anything on the page. Sometimes we only need to print the data table, and then we need to write a style: hide the part that you do not want to print:
Style content:
<Style type = "text/CSS" Media = print>
. Noprint {display: None}
</Style>
Then you can use the style:
<P class = "noprint"> No printing required </P>

The Code is as follows:

<Script language = "JavaScript">
Function printsetup (){
// Print page settings
Wb.exe CWB (8, 1 );
}
Function printpreview (){
// Print the Page Preview

Wb.exe CWB (7,1 );

}

Function printit ()
{
If (confirm ('Are you sure you want to print? ')){
Wb.exe CWB (6, 6)
}
}
</SCRIPT>

<Object classid = "CLSID: 8856f961-340a-11d0-a96b-00c04fd705a2" Height = 0 id = WB name = WB width = 0> </Object>
<Input type = button name = button_print value = "print" class = "noprint" onclick = "javascript: printit ()">
<Input type = button name = button_setup value = "print page settings" class = "noprint" onclick = "javascript: printsetup ();">
<Input type = button name = button_show value = "print preview" class = "noprint" onclick = "javascript: printpreview ();">
