>I have HTML page displaying a table. I do not want certain portion of text to be printed. Using white font color on a some backgroung (bgcolor="#336666" color="#FFFFFF") did not help. Is here any trick to hide text when printing?

In addition to the other suggestion you got, you can also use a standard approach that many Web sites are using by forwarding the print to another page. That page would be pretty much such as you have minus the attributes that you do not want to print.
