Abstract: A printing system including a print engine, a drying module, and a heating module. The print engine applies printing fluid on media. The drying module dries the printing fluid and provides dried printing fluid. The heating module applies thermal energy to the dried printing fluid and transitions the dried printing fluid to a cured printing fluid that has improved durability versus the dried printing fluid.
