In Internet Explorer, you can highlight the part you want to print (move mouse pointer to beginning of wanted section, press and keep pressed left mouse button, move mouse pointer to end of wanted section). Then go to File menu and choose Print... command (do NOT use the Print icon in the toolbar as this tends to print the hole page!). In the print dialog, in the print range box, select the radio button for "Selection" This should print just the highlighted part of the page (without you having to know which pages these are).
In Netscape it should work the same (but my 6.0 PreRelease installation disables the "Selection" and "Pages" radio buttons
