This is the fundamental program on a computer, the first thing it loads, which tells it to stop being an inert lump of plastic, silicon and metal and to start paying its way.
Although solvent and light solvent inks are touch-dry when they come off the printer, they continue to evaporate and 'outgas' for some hours. If you need to add a laminated surface it has to wait until outgassing finishes, or bubbles may form. Several types of ink have been developed that do not outgas, including aqueous, (though that has separate drying issues), UV-cured, latex and most recently, solvent-UV hybrids that contain very little solvent.
