An enhanced printing system comprises a drum structure, a print carriage for delivering LED curable ink there from, such as from one or more print heads, and one or more LED light sources for curing the delivered ink. Some embodiments may preferably further comprise one or more LED pining stations, such as to control, slow or stop the spread of ink drops. As well, some printer embodiments may comprise a mechanism to deliver any of an inert gas, e.g. nitrogen, or other gas that is at least partially depleted of oxygen, between the LED energy source and the substrate. The disclosed LED printing structures typically provide higher quality and/or lower cost as compared to prior art systems, for a wide variety of printing matter output, such as for but not limited to super wide format (SWF) output, wide format (WF) output, packaging, labeling, or point of sale displays or signage.
