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)
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 ...
The other motivation for driver synthesis, is the large number of flavors of operating systems and device combinations. Each of these has its own set of input/output control and specifications which makes support of hardware devices on each of the operating systems difficult. So the ability to use a device with an operating system requires the ...
A programmable logic controller (PLC) or programmable controller is an industrial computer that has been ruggedized and adapted for the control of manufacturing processes, such as assembly lines, machines, robotic devices, or any activity that requires high reliability, ease of programming, and process fault diagnosis.
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.
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.
The OPC specification was based on the OLE, COM, and DCOM technologies developed by Microsoft Corporation for the Microsoft Windows operating system family. The specification defined a standard set of objects , interfaces e.g. IDL and methods for use in process control and manufacturing automation applications to facilitate interoperability .
A driver in software provides a programming interface to control and manage specific lower-level interfaces that are often linked to a specific type of hardware, or other low-level service. In the case of hardware, the specific subclass of drivers controlling physical or virtual hardware devices are known as device drivers.
