title: Safe width in pixels for printing web pages?
body: <p>What is the safe width in pixels to print a web page? </p>
  
  <p>My page includes large images and I want to make sure they will not be cut of when printed.</p>
  
  <p>I know about different browser margins and US Letter / DIN A4 paper sizes. So we got standard letter sized and some default DPI values. But can I convert these into <strong>pixel</strong> values to specify in the image's <code>width</code> attribute?</p>
