Hi cinemasign.grafix
just to make a case in favor of the online heater. If your not hurting for the cash, its a worth while investment. what mark said was true about profiling and settings but there is also a heaping time investment associated with that too.
the online heater takes the guess work out. your prints are dry for certain. with out it your prints may be dry to the touch but you still need to wait for them to "gas out" before use (installation, lamination, etc). The online heater makes certain my prints are dry. Some days i come in to the shop, load a 80' roll of banner material and let it print from edge to edge with out a second thought about making sure the media is dry as the take up reel rolls it up.
think if it as a new car. sales guys tells you, " ...for a few hundred more, I'll throw in leather and premium sound, and a turbo package."
the online heater makes your printer the "total package"
