php/pdf configuration project

We have calculator code written in .php hosted on shared server. This code has option to generate detailed report in the website and also it gives a link to generate the .pdf format for this to download. We have recently moved our server and now we are facing some configuration issues on [login to view URL] server. The pdf files are executing fine but it doesn’t generate .pdf files and shows some junk characters instead. Please have a look at this website: [login to view URL] When u click on the pdf link “Let Me Print That Form in PDF!” it will pop up a new window with some junk. We just need this pdf thing to work correctly. There can some configuration issues on server or may need code enhancement. But this code was working perfectly on previous server so I think configuration may be the only issue. PLease see the attached source code You need to test it on your server and once its working fine. You have upload and configure the site on godaddy/our server too. The required information to upload at our server will be provided later.
