HP 5100tn Printer Job Language - Technical Reference Manual - Page 299

Poorly Formed Print Job A print job which either starts or ends with an invalid data stream sequence. For example, any job that does not begin and end with a UEL command is a poorly formed job. This manual describes how to create properly formed print jobs and contains many examples to demonstrate them. See Chapters 1 - 3 and Chapter 10 for more information about creating well-formed jobs. Print Environment The group of all the printer's current feature settings, collectively, is referred to as the print environment. The print environment is modified using printer commands and control panel settings. Printer Language A set of syntax and semantic rules used to control a printer. PCL and PostScript are both printer languages-they both contain commands that enable the user to control where marks are printed on a page. Ready Message A ready message is displayed on the control panel display when no error conditions are present. When errors occur, an error message replaces the ready message until the situation is corrected or the printer autocontinues. The PJL RDYMSG command is used to specify a ready message to replace the "00 READY" message. Secure PJL Job A "secure" PJL job is a job that contains the correct password in the JOB command. For the LaserJet 4Si/4SiMx printers, secure jobs are able to use the DEFAULT and INITIALIZE commands. (The LaserJet 4 Plus, 4M Plus, 4V, 4MV, 4Si, 4SiMx, 4000 series, 5, 5M, 5P, 6P, 5Si, 5SiMx, and the 5Si Mopier are the only printers that support the password option of the JOB command.) Glossary-7
