In some examples, printing device temperature management may include ascertaining a print speed associated with a print job, and comparing the print speed to a print speed threshold. Printing device temperature management may further include actuating a power supply associated with a print bar at a start position of physical medium to be utilized for printing for the print job, or at or beyond a specified location along a path associated with traversal of the physical medium from the start position to a print zone to reduce an operational temperature associated with the print bar.

In one example of the disclosure, a printer includes a printhead having a set of nozzles. Printing ejection of marking agent is caused upon a media to print each of a set of pages of a print job. An initial page spit is caused to occur at the printhead prior to the printing engine causing printing of an initial page of the print job. A between-pages spit is caused to occur at the printhead between printing of pages of the print job. Responsive to a determination that a predetermined period between printing of a page and a consecutive page of the print job has been exceeded, a gap spit is caused to occur at the printhead in lieu of a between-pages spit.

Gap spits at printheads

A printer includes a print media transport to transport a print media through a print zone, the transport of the print media to produce airborne particles, and a particle diverter to divert the airborne particles away from the print zone from a vicinity of the print media transport.

An apparatus includes a differential to receive a primary driving force, and provide a first driving force and a second driving force. A first pick wheel is to transfer the first driving force to a sheet. A second pick wheel is to transfer the second driving force to the sheet. The differential is to balance the first driving force and the second driving force to reduce skew in the sheet and feed the sheet along a feed path of a printer. The first pick wheel and the second pick wheel are aligned perpendicular to the feed path at an offset from the differential.
