HP 5100 Printer Job Language - Technical Reference Manual - Page 296

Glossary-4 Implicit Switching Implicit switching occurs when a printer language is activated due to reception of non-PJL data which is not preceded by a PJL ENTER command. (See contextsensitive printer language selection.) Job Boundary The beginning or end of a print job. The position between two characters of data in the data stream where the previous character is the last character of the previous print job, and the next character is the first character of the next print job. Macro A macro is a collection of escape sequences, control codes, and data downloaded to the printer. Its execution can be initiated using a single command. Modified Print Environment Once a printer language, such as PCL, is entered, the current feature settings constitute the modified print environment. Whenever a feature setting is altered using printer language commands, the new setting is recorded in the Modified Print Environment. Non-Printing Mode Printing selected pages in a print job by sending the entire print job, the desired starting page number, and the ending page number. The PJL JOB command options START and END are used to provide the starting page number and the ending page number. When the printer processes the pages that are not printed, the printer is said to be in non-printing mode.
