    Abstract: According to one example, there is provided a system for compensating for changes in printhead-to-printhead spacing in a printing system having multiple printheads mountable on a printhead support. The system comprises a measurement system to determine a change in printhead-to-printhead spacing between different ones of mounted printheads, and a processor to determine compensation to be applied to the printing system to compensate for the determined change in printhead-to-printhead spacing.

    Abstract: An uncoated recording medium includes a blend of hardwood and softwood chemical pulp fibers, and thermomechanical pulp (TMP) fibers, with total fiber content at least 80 wt % of the medium's total wt %. Hardwood fibers range from about 20 wt % to about 70 wt %, softwood fibers range from about 30 wt % to about 50 wt %, and TMP fibers range from about 10 wt % to about 30 wt %, all relative to the total fiber content. A TiO2 amount ranges from about 1.5 wt % to about 6 wt % of the total wt %, and a bivalent or multivalent salt amount ranges from about 6,000 to about 16,000 μg/gram of the medium. The basis weight ranges from about 45 g/m2 to about 63 g/m2.

    Abstract: An integrated circuit to drive a plurality of fluid actuation devices includes a plurality of contact pads, a plurality of pulldown devices, and control logic. The plurality of contact pads include a first contact pad and a second contact pad. Each of the pulldown devices is electrically coupled to a corresponding contact pad. The control logic enables at least a portion of the pulldown devices in response to both a logic low signal on the first contact pad and a logic low signal on the second contact pad.
