I have eliminated printing unneeded parts of my sites pages - including wrapping a noprint span class around self placed Adsense units (which now do not show on print preview) - using classes/ids display:none in @media print CSS.
However the auto-inserted "here an ad, there an ad, everywhere an ad ad," Adsense units keep showing on printed page. Anyone had this trouble, or know what class/ID to target to stop them showing when printing?
