A control panel called RAM Charger causes this printing conflict. The printing problem can be eliminated by removing RAM Charger from the Control Panels folder (making it totally inactive) or by leaving it active and telling it to NOT "optimize" ChemDraw (click on RAM Charger icon, which is normally displayed on the upper right corner of the desktop, right under the Finder icon, and deselect ChemDraw from the list of programs that RAM Charger will "optimize").
