HTML in PHP to a File

I have a PHP file that outputs HTML to the Internet to a user. The user also wants to be able to print that output to a printer. The user wants it formatted with page breaks in the proper place and so on. Using one PHP script to do both, short of a line to display and a line to print, is there a way to do this easily or am I in a pond of alligators? Most of the output is using an echo statement. I thought of trying to take a var and set it top echo or write according to what is needed at that time. Here is my minitest. <?php echo "<P>The test is starting"; $echowrite = "echo "; $echowrite."<P>This is the first line."; echo "<P>You should have seen the first line by now."; ?> Did not work! Hey I'll try anything to get this to work! LOL Seriously, how can this be done? Thanks. Mike
