Web Printing opens an empty windows

Hi developers,

I've tried to apply the file: "How To Enhance Web Printing".

I've applied all the adds to the HTML code as suggested by the file, but the system opens a new page empty. The URL of the new explorer page is: http://172.24.40.56:8045/sap/bw/BEx?SAP-LANGUAGE=I&PAGENO=2&CMD=PROCESS_HELP_WINDOW&HELP_SERVICE=ZPRINTING&ITEM=Table_1&REQUEST_NO=1

Any ideas how can I solve my problem?

Thanks in advance!

Domenico
