PCL 6 Standard: Equivalent to PCL 5e or PCL 5c, intended to provide backward compatibility. Font synthesis : Provides scalable fonts, font management and storage of forms and fonts. PCL 6 "Enhanced" architecture was altered to be more modular and to be more easily modified for future HP printers, that it prints complex graphics faster, that it ...
Using another lower-level device driver (e.g. file system drivers using disk drivers) Simulating work with hardware, while doing something entirely different [9] For software: Allowing the operating system direct access to hardware resources; Implementing only primitives; Implementing an interface for non-driver software (e.g. TWAIN)
Install-able drivers can be packaged in various formats. PPD is a popular packaging format for drivers that accept Postscript data or PDF data as input. Due to dominance of select operating systems, the operating system–driver interface is more standardized than driver–printer interfaces.

So the ability to use a device with an operating system requires the availability of corresponding device driver combination. Hardware vendors usually supply the drivers for Windows, Linux and Mac OS but due to the high development or porting costs and technical support difficulties they are unable to provide drivers on all platforms. An ...
The operating system provides an interface between an application program and the computer hardware, so that an application program can interact with the hardware only by obeying rules and procedures programmed into the operating system. The operating system is also a set of services which simplify development and execution of application programs.
An overlapping term is printer control language, which includes Hewlett-Packard's Printer Command Language (PCL). PostScript is one of the most noted page description languages. The markup language adaptation of the PDL is the page description markup language.
In embedded systems, a board support package (BSP) is the layer of software containing hardware-specific boot loaders, device drivers and other routines that allow a given embedded operating system, for example a real-time operating system (RTOS), to function in a given hardware environment (a motherboard), integrated with the embedded operating system.
