HP Universal Print Driver (UPD) is an intelligent print driver that supports a broad range of HP print devices, such as LaserJet and various MFPs. Developed by Hewlett-Packard , HP UPD combines a general purpose driver ( XPSDrv , UniDrv , or PSCRIPT ), print control, and HP proprietary extensions.
HP Open Extensibility Platform (HP OXP), developed by Hewlett-Packard Co., is an enterprise software development platform that consists of three unique layers.1) HP OXPd, the device layer, enables document workflow applications, 2) HP OXPm, the management layer, exposes functionality for management software like HP Web Jetadmin, and 3) HP OXPw, the workflow layer, embeds web services ...
Through the use of the Printer Preferences program printers could be connected to the serial port as well. Amiga also had support for a virtual device "PRT:" to refer to printer.device so, for example the command "COPY file TO PRT:" caused the file to be printed directly bypassing parallel.device and the default printer driver.
Finally the call device.controlTransferOut() will set up the device to communicate through the WebUSB Serial API. Once the set up is all done, data can be transferred to the device using device.transferIn() to transfer bulk data to the device, similarly its sister function device.transferOut() to read data from the device.

Printer Job Language (PJL) is a method developed by Hewlett-Packard for switching printer languages at the job level, and for status readback between the printer and the host computer. PJL adds job level controls, such as printer language switching, job separation, environment, status readback, device attendance and file system commands.
The Internet Printing Protocol (IPP) is a specialized communication protocol used between client devices (computers, mobile phones, tablets, etc.) and printers (or print servers). The protocol allows clients to submit one or more print jobs to the network-attached printer or print server, and perform tasks such as querying the status of a ...
Changes to files in folders that standard users don't have permissions for (such as %SystemRoot% or %ProgramFiles% in most cases) Changes to an access control list (ACL), commonly referred to as file or folder permissions; Installing and uninstalling applications outside of: The %USERPROFILE% (e.g. C:\Users\{logged in user}) folder and its sub ...
Write blocking, a subset of write protection, is a technique used in computer forensics in order to maintain the integrity of data storage devices. By preventing all write operations to the device, e.g. a hard drive, it can be ensured that the device remains unaltered by data recovery methods.
