Hewlett-Packard Raster Transfer Language
The Hewlett-Packard Raster Transfer Language (HP RTL) is a subset of the Printer Command Language (PCL) language. It is used to embed true raster images (bitmaps) into plotter files. Modern plotters (like HP DesignJets) are raster devices, so they need a raster-based language. For backward compatibility they also support the HP-GL/2 (formerly HP-GL HP-GL, short for Hewlett-Packard Graphics Language and often written as HPGL, is a printer control language created by Hewlett-Packard (HP). HP-GL was the primary printer control language used by HP plotters. It was introduced with the plotteHP ...) vector language, so the HP RTL language is designed for mixing with the HP-GL/2 language.

Printer Command Language
Printer Command Language, more commonly referred to as PCL, is a page description language (PDL) developed by Hewlett-Packard as a printer protocol and has become a ''de facto'' industry standard. Originally developed for early inkjet printers in 1984, PCL has been released in varying levels for thermal, matrix, and page printers. HP-GL/2 and PJL are supported by later versions of PCL. PCL is occasionally and incorrectly said to be an abbreviation for ''Printer Control Language'' which actually is another term for page description language. PCL levels 1 through 5 overview PCL levels 1 through 5e/5c are command-based languages using control sequences that are processed and interpreted in the order they are received. At a consumer level, PCL data streams are generated by a print driver. PCL output can also be easily generated by custom applications. *PCL 1 was introduced in 1984 on the HP ThinkJet 2225 and provides basic text and graphics printing with a maximum resolution of 1 ...

Plotter
A plotter is a machine that produces vector graphics drawings. Plotters draw lines on paper using a pen, or in some applications, use a knife to cut a material like vinyl or leather. In the latter case, they are sometimes known as a cutting plotter. In the past, plotters were used in applications such as computer-aided design, as they were able to produce line drawings much faster and of a higher quality than contemporary conventional printers. Smaller desktop plotters were often used for business graphics. Printers with graphics capabilities took away some of the market by the early 1980s, and the introduction of laser printers in the mid-1980s largely eliminated the use of plotters from most roles. Plotters retained a niche for producing very large drawings for many years, but have now largely been replaced by wide-format conventional printers. Cutting plotters remain in use in a number of industries. Overview Digitally controlled plotters evolved from earlier fully analog ...

HP-GL/2
HP-GL, short for Hewlett-Packard Graphics Language and often written as HPGL, is a printer control language created by Hewlett-Packard (HP). HP-GL was the primary printer control language used by HP plotters. It was introduced with the plotteHP-8972in 1977 and became a standard for almost all plotters. Hewlett-Packard's printers also usually support HP-GL/2 in addition to PCL. Design The language is formed from a series of two letter codes (mnemonics), followed by optional parameters. For instance an arc can be drawn on a page by sending the string: AA100,100,50; This means ''Arc Absolute'', and the parameters place the center of the arc at absolute coordinates 100,100 on the page, with a starting angle of 50 degrees measured counter-clockwise. A fourth optional parameter (not used here) specifies how far the arc continues, and defaults to 5 degrees. When first introduced, HP-GL contained the following commands: Formats: * integer formats between -32767 and 32768. No ...
