USB On-The-Go (USB OTG or just OTG) is a specification first used in late 2001 that allows USB devices, such as tablets or smartphones, to also act as a host, allowing other USB devices, such as USB flash drives, digital cameras, mouse or keyboards, to be attached to them. Use of USB OTG allows devices to switch back and forth between the roles ...
A printing protocol is a protocol for communication between client devices (computers, mobile phones, tablets, etc.) and printers (or print servers).It allows clients to submit one or more print jobs to the printer or print server, and perform tasks such as querying the status of a printer, obtaining the status of print jobs, or cancelling individual print jobs.
Today, the parallel port interface is virtually non-existent in new computers because of the rise of Universal Serial Bus (USB) devices, along with network printing using Ethernet and Wi-Fi connected printers. The parallel port interface was originally known as the Parallel Printer Adapter on IBM PC-compatible computers.
Beyond driver configuration, HP UPD also employs managed printer lists (MPLs) and managed print policies (MPP) to control access to devices and capabilities. These technologies are used with HP UPD in dynamic mode. If MPLs are used, then searching for devices is unnecessary. Users are presented with a predefined list of devices from which to ...
USB 3.0 provides two additional differential pairs (four wires, SSTx+, SSTx−, SSRx+ and SSRx−), providing full-duplex data transfers at SuperSpeed, which makes it similar to Serial ATA or single-lane PCI Express. Standard, Mini-, and Micro-USB plugs shown end-on, not to scale. Light areas represent cavities.
USB keyboards, mice, and I/O devices are the most common devices connected to a KVM switch. The classes of KVM switches discussed below are based on different types of core technologies, which vary in how the KVM switch handles USB I/O devices—including keyboards, mice, touchscreen displays, etc. (USB-HID = USB Human Interface Device)

PoweredUSB, also known as Retail USB, USB PlusPower, USB +Power, and USB Power Plus, [1] is an addition to the Universal Serial Bus standard that allows for higher-power devices to obtain power through their USB host instead of requiring an independent power supply or external AC adapter.
