For most printer settings, you'll need to change them from the Print dialog that comes up when you select print. That lets you select the printer and the settings for that printer. Otherwise, within GCA, you can mostly just change page settings as displayed in preview and sheet view.

(I see print settings is still on the File menu, although it is disabled. That should actually be removed as those apply when printing, as mentioned above, and therefore need to be set from inside the Prrint dialog.)
