i have tried to print a page through client button click event.but it shows an error as printer has not installed.so i want to check whether printer is installed on this computer or not.if yes i want to proceed else alert the user.

this i want to do in javascript.. 

Before you can perform printer-related tasks shch as page setup or printing a document,you need to install a printer. do you want to install a printer now? .

Javascript has no access to printer properties, so you can't do this.  You would need to develop a control that runs in the client browser, such as an ActiveX control, and you need them to download and install it.

samuelchandradoss:

i think u misunderstood my need. I want to know whether printer is installed or not on the system by javascript .

No - you misunderstood my reply.  You cannot use javascript to do this.  It has no access to printers, printer properties, the file system or port information on the user's machine.  Therefore, it is impossible to find out by using javascript if a user has a printer installed. 

function CallPrint( strid ) { try { var prtContent = document.getElementById(strid); var WinPrint = window.open('', '', 'left=0,top=0,width=900,height=600,toolbar=1,scrollbars=1,status=0'); WinPrint.document.write( prtContent.innerHTML ); WinPrint.document.close(); WinPrint.focus(); WinPrint.print(); WinPrint.close(); //prtContent.innerHTML=strOldOne; } catch(err) { alert("hai"); txt+="Error description: " + err.description + "\n\n"; txt+="Click OK to continue.\n\n"; alert(txt); return false; } }

it is the java script to print a content present on the div,
