Abstract: Example implementations relate to point of sale cables. For example, a system may comprise a point of sale terminal coupled to a splitter via a registered jack (RJ) cable to provide electrical power to the splitter, a receipt printer coupled to receive electrical power from the splitter at a DIN connector input, and a cash drawer to receive electrical power from the splitter via an RJ connector input.

Abstract: Example latching assemblies and electronic devices including the latching assemblies are disclosed. In an example, an electronic device includes a housing including a cavity to receive a peripheral device therein. In addition, the electronic device includes a latching assembly disposed within the housing. The latching assembly includes a latch biased toward the cavity to engage with the peripheral device, and a block. Displacement of the block is to slidingly engage the block along the latch and thereby withdraw the latch from the cavity.

Abstract: In an example, a device includes a display, a stand, and a printing device. The stand is positioned beneath and supports the display, and has a cylindrical shape. The printing device is housed within the stand and includes a spindle, a roller, a fluid ejection die, and a cutting mechanism. The spindle supports a roll of paper. The roller unrolls the paper from the roll of paper. The fluid ejection die ejects fluid onto the paper as the paper unrolls from the roll of paper. The cutting mechanism severs a portion of the paper from the roll of paper.
