Hewlett Packard printer Command Language (Printer Languages)
Hp PCL or Hewlett Packard printer Command Language was presented by the Hewlett-Packard. That is elevation of organize system, device drivers, I/O interface, and network communications. Its purpose is to carry all HP printers with each other under a common control structure. HP provided it in that first desktop computer laser printer. PCL is an Escape password language. HP has been making use of this language because that its dot-matrix and inkjet printers prior to the creation of laser printers. PCL regulates are compact escape sequence codes the are embedded in the print job prior to being sent to the printer. PCL fonts quickly translate application output right into high quality raster print images. PCL has actually several versions available.
You are watching: Which of the following are printer languages
PCL 1 was presented in 1980. The is an easy language having actually capabilities for basic printing. PCL 1 prints nothing however only text. Sustained by every HP LaserJet series printers (except the HP LaserJet 3100 and also 3150 series products).
PCL 2 added Electronic Data Processing/Transaction functionality. supported by every HP LaserJet collection printers (except the HP LaserJet 3100 and 3150 series products).
It detailed the commands and also features compelled for straightforward high top quality word processing and also data printing. Permitted for the use of a minimal number the bitmapped fonts and graphics.
PCL 3 listed simple native processing and also data sharing. It supported not only small bitmap fonts however also little bitmap graphic printing. Plenty of other manufacturers emulate PCL 3 referred to as LaserJet plus emulation. PCL 3 is quiet in use on several influence printers which replaced the obsoleted HP models. It does not support downloadable or scalable fonts. It is pixel based press language that primarily explains images through pixel.
Released with the following printers: HP LaserJet series II, HP LaserJet IID, HP LaserJet IIP, and also HP LaserJet IIP Plus collection printers.
Provided brand-new page to press capabilities. Supported macros, larger bitmapped fonts and graphics. Presented in 1985.
The LaserJet Plus printer was superseded by the LaserJet collection II, additionally an 8 p.p.m. Printer. The LaserJet II series of printers consisted of the LaserJet IIP, a 4 p.p.m. Personal printer, and also the LaserJet IID, a duplex version of the LaserJet II. The LaserJet II introduced the PCL 4 language, which built upon PCL 3 by including the ability to use more, bigger bitmap fonts, and an ext bitmap graphics. The traditional LaserJet II could manage just over half a web page of bitmap graphics, but with the enhancement of part extra storage this can be expanded to a totality page.
PCL 4 was presented on the HP LaserJet II in 1985, adding macros, larger bitmapped fonts and graphics. PCL 4 is still famous for countless applications.
PCL 4 was backwards compatible v PCL 3 (PCL 3 tasks would print perfectly fine under PCL 4), yet the added features took it well past the bounds of word-processing, and permitted it to be used for charts, graphics and simple desktop publishing. PCL 4 has actually been superseded for office printers, but is still commonly used in personal printers together it requires fairly little handling power in compare with later on versions that the PCL language. The version of PCL 4 used on the LaserJet IIP was a slightly intensified over the version supplied on the standard LaserJet, and detailed a compression method for bitmap graphics to alleviate the amount of data which the computer had come send to the printer.
