[Plugin: Print Button Shortcode] Not working with IE

I found the root cause.

IE doesn’t like the new window name to have spacebar. So we must change this line
w=window.open(null, 'Print_Page', 'scrollbars=yes');

Then we still cannot print yet. There must be this line
w.document.close();
before the print command
w.print();

Now it works.

I am having the same problem you had. Thanky you for posting your solution. What did you do to change the line
w=window.open(null, ‘Print_Page’, ‘scrollbars=yes’);

Did you do anything to edit any other lines or did you just insert the w.document.close(); line on the line before w.print(); ?

Just edit and insert the lines you mentioned, as I remember.
