LaserWriter Select 310 Hardware

Interactive Mode

1

You can use the LaserWriter Select 310 printer as a personal computer, and control it directly by means of a terminal or other input device. This way of using the printer is known in this context as interactive mode. It allows you to experiment with the PostScript language.

In interactive mode, a job consists of a long dialogue, in which you issue a PostScript language statement, and the server executes the statement and prompts for the next one. The state of the PostScript interpreter’s virtual memory persists until you explicitly end the job. While you are entering a statement, the printer echoes characters and provides you with limited means for making corrections.

The imageable area of a page (the area in which printed matter may appear) is referred to as the page size. Page size constrained by

■the physical size of the paper

■the margins required by the printing engine

■the amount of memory available for the full-page frame buffer

Table 1-5 lists the range of paper sizes supported by the LaserWriter Select 310 printer.
