Abstract: A drying apparatus usable with a printing system includes a housing, a first set of radiative heating elements, a second set of radiative heating elements, and an air handling device. The housing includes a front region and a rear region adjacent to the front region. The front region includes an inlet to receive media. The rear region includes an outlet to pass media there through. The first set of radiative heating elements is disposed within the front region to heat the media. The second set of radiative heating elements is disposed within the rear region to heat the media. The air handling device is disposed across from the second set of radiative heating elements to jet air within the rear region to cool the media prior to the media being passed through the outlet.

Abstract: In one example, an inkjet web printer includes: an arched printing unit and an aerosol control system. The printing unit has a series of printheads arranged along an arc and multiple rollers to support a print substrate web along the arc through a print zone adjacent to each printhead. The aerosol control system has a vacuum duct through which air may be sucked away from the web leaving a print zone adjacent to one of the printheads and a pressure duct through which air may be blown on to the web leaving the print zone. The pressure duct is positioned downstream from the vacuum duct and configured to blow air diagonally upstream directly on to the web at the same location the vacuum duct is to suck air away from the web.

Abstract: In an example implementation, a processor-readable medium stores code representing instructions that when executed by a processor cause the processor to initiate motion of a media web in an inkjet web press, begin printing a print frame based on a start pulse from a metering device, verify that printing the print frame is complete, receive a signal from the metering device that a frame-length of the media web has been measured at the output of the press, and begin printing a new print frame based on the verification and the signal.

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.

Abstract: In an example, an apparatus is described that includes a first print section, a second print section, a dryer, and a printing path. The first print section includes a first fluid ejection array, while the second print section includes a second fluid ejection array. The dryer is positioned adjacent to the first print section and the second print section. The printing path that travels in a first direction through the dryer after exiting the first print section and travels in a second direction through the dryer after exiting the second print section.
