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.
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.
DOS—Disk Operating System; DP—Dot Pitch; DPC—Deferred Procedure Call; DPI—Deep packet inspection; DPI—Dots per inch; DPMI—DOS Protected Mode Interface; DPMS—Display Power Management Signaling; DR—Disaster Recovery; DRAM—Dynamic Random-Access Memory; DR-DOS—Digital Research – Disk Operating System; DRI—Direct Rendering ...
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.
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 ...
OPC servers provide a method for different software packages (as long as it is an OPC client) to access data from a process control device, such as a programmable logic controller (PLC) or distributed control system (DCS). Traditionally, any time a package needed access to data from a device, a custom interface or driver had to be written.
