Abstract: An example of a printing fluid supply connector is described that has a first connector and a second connector, where each of the first and second connectors is to fluidly connect to a respective replaceable reservoir of printing fluid. The printing fluid supply connector also has an outlet to fluidly connect to a printer and a selector to selectively fluidly connect one of the first and second connectors to the outlet in response to an electrical control signal or to fluid pressure at the first and second connectors.

Abstract: In one example, there is disclosed a print device 100 comprising: a print fluid supply pathway 102 extending from a reservoir inlet 104 to a printhead outlet 106; a valve 108 in the print fluid supply pathway 102 downstream of the reservoir inlet 104: a pressure sensor 110 to monitor print fluid pressure upstream of the valve 108; a pressure sensor controller 112 to temporarily close the valve 108 for a closed period and monitor print fluid pressure using the pressure sensor 110 during the closed period; and a print operation controller 114 to control printing operations of the print device 100 so that in use a printing operation continues and print fluid is discharged from a printhead 234 during a closed period of the valve 108 in the respective print fluid supply pathway 102.

Abstract: Printing apparatus (10) including a controller (12) to control supply of at least a first predetermined amount of power to a first heater (18) while the first heater is moving through a print zone (40), and to control supply of at least a second predetermined amount of power to the first heater (18) while the first heater is outside of the print zone (38), the second predetermined amount of power being less than the first predetermined amount of power.

Abstract: A printing apparatus includes a carriage, a first detector module, and a second detector module. The carriage may selectively move a fluid applicator along a scanning path in a first scanning direction and a second scanning direction across a print zone to print on a media therein. The first detector module and second detector module may be coupled to the carriage. Further, the first detector module may include a first receiver and a first source to form a first detection region there between downstream of the carriage in the first scanning direction to detect an object therein. The second detector module may include a second receiver and a second source to form a second detection region there between downstream of the carriage in the second scanning direction to detect an object therein.
