Abstract: A print medium can include a cellulose-based paper substrate with a first surface and a second surface opposite the first surface. The first surface can be treated with an electrically charged treatment layer. An ink-absorbing layer can be positioned on the electrically charged treatment layer. The ink-absorbing layer can include a polymeric binder and surface-activated fumed silica particles. The surface-activated fumed silica particles can include fumed silica particles that are surface-activated with charged multivalent aluminum salt and organosilane reagent. In further detail, an ink-receiving layer can be positioned on the ink-absorbing layer. The ink-receiving layer can include amorphous silica particles, alumina particles, or a combination thereof.

Abstract: Examples of printing device calibration based on a lot code are described. In an example, a lot code of a print media is determined. Calibration parameters for a printing device are determined based on the lot code. The printing device is calibrated to print on the print media based on the calibration parameters.
