title: guaranteeing print dimensions / layout for a dynamically generated html page
body: <p>I have a page that I need to design in PhP/Html/Java/CSS that has to be printed out Exactly to a certain size on the clients printer. The printer uses labels (similar to fedex/ups) that have multiple parts, and the design is made so that the label, when seperated into its parts, has certain data on each.</p>
  
  <p>Any advice on the exact way to guarantee my page prints out properly on say a 5x7 label?</p>
  
  <p>I have full control of the design, but all css must be done in-line.</p>
  
  <p>The device that prints it will not scale anything. Once designed, this page's only purpose is to be printed on this device. Usability, design, all of that is unimportant as long as it prints this label correctly on this printer. The printer may be hooked up to multiple different PC's, or multiple PC's may be printing this page to the same printer/same model printers.</p>
  
  <p>is there any easy way other than "guess and check"?</p>
