In this while loading the nsIFile component its throwing an error ReferenceError: urls is not defined.

If I remove the code and run this code only for single file works good but for directory iteration I require that.

Reproducible: Always

Steps to Reproduce:
1.run the code simply giving input and output path
2.
3.

This is not a security bug.  This is not even a bug in Mozilla, but a bug in your own code.  When you call |file.initWithPath(urls)| you are passing an undefined variable as the argument.  Everywhere else in your code you are using |url|.

Yes I got it afterwords,

Now I have Modified the code.

Now I am giving I am iterating a directory and giving a single file one after the other for pdf generation but my code throws following exception

"[Exception... "Component returned failure code: 0x8048001f [nsIWebBrowserPrint.print]"  nsresult: "0x8048001f (<unknown>)"  location: "JS frame :: chrome://html2pdf/content/html2pdf.js :: anonymous :: line 124"  data: no]

and the line where the code is throwing an error is

This is a bug tracking database for Mozilla products, not a developer support tool.  Have you tried searching the error message?  Did you look at the line number that the error message refers to to debug your code?  You're going to need to demonstrate a little more resourcefulness if you want people to help you, in general.
