If i show the print dialog box, then it consume some seconds to give the print , see i done have more printer, i have only one printer ,that is dot matrix, when ever i give print command , then it should print the BILL without open the print dialog box,

Download Google Chrome Version 18.xx.xx.xx and you can use flags to turn OFF the printer dialog

--kiosk-noprint

Something of that fashion I can't quite remember off the top of my head but google will help on that. That will allow the dialog to stay out of the way when you select whatever you want to print.

This is totally possiable. I work in banking and had a webpage that tellers needed to auto print when a transaction was posted. Since they do transactions all day it would slow them down if they had the dialog box display everytime. This code will select your default printer and print directly to it with no dialog box.

<form>
<input type="button" value="Print Page" onClick="window.print()">
</form>


<script language="VBScript">
// THIS VB SCRIP REMOVES THE PRINT DIALOG BOX AND PRINTS TO YOUR DEFAULT PRINTER
Sub window_onunload()
On Error Resume Next
Set WB = nothing
On Error Goto 0
End Sub

Sub Print()
OLECMDID_PRINT = 6
OLECMDEXECOPT_DONTPROMPTUSER = 2
OLECMDEXECOPT_PROMPTUSER = 1


On Error Resume Next

If DA Then
call WB.ExecWB(OLECMDID_PRINT, OLECMDEXECOPT_DONTPROMPTUSER,1)

Else
call WB.IOleCommandTarget.Exec(OLECMDID_PRINT ,OLECMDEXECOPT_DONTPROMPTUSER,"","","")

End If

If Err.Number <> 0 Then
If DA Then 
Alert("Nothing Printed :" & err.number & " : " & err.description)
Else
HandleError()
End if
End If
On Error Goto 0
End Sub

If DA Then
wbvers="8856F961-340A-11D0-A96B-00C04FD705A2"
Else
wbvers="EAB22AC3-30C1-11CF-A7EB-0000C05BAE0B"
End If

document.write "<object ID=""WB"" WIDTH=0 HEIGHT=0 CLASSID=""CLSID:"
document.write wbvers & """> </object>"
</script>

It's not possible, and there are a few good reasons for that:

• the user could want to choose a printer himself
• the user could want to be able to control when his printer gets activated (imagine nasty auto-selfprinting advertisement popups, ARRGH!)
• the user could want to specify printer settings (grayscale or color, resolution, size, ...)

I think the best alternate will be either Flash or Java....

Flash is very flexible in terms of customizing the OS elements....

So, user can define Printers through he want to print and you can just pass the name of the printer to the function and that printer will start printing.....
