LaserWriter Select 310 Hardware

The LaserWriter Select 310 printer is an economical laser printer that supports PostScript™ Level 1 functions. It executes page descriptions written in the PostScript language, and it produces printed pages at a rate of up to five pages per minute. The raster printing technology is xerographic, black and white, and write black at 300 dots (pixels) per inch. The printer is dedicated, and it operates with Macintosh computers using the RS-232 serial port or with DOS-based IBM personal computers using the Centronics parallel port. It is available in 110-volt and 220-volt versions.

The LaserWriter Select 310 printer supports the entire PostScript language specified in the first edition of the PostScript Language Reference Manual. In addition, it has features, capabilities, and operating modes not present in other PostScript language printers. You may access these additional facilities by executing special PostScript operators that exist only in the LaserWriter Select 310 printer’s PostScript interpreter.

Unlike other Apple LaserWriter printers, the LaserWriter Select 310 printer does not have a rotary selection switch to allow you to select different communication protocols.

In addition, the printer does not have EEROM (electronically erasable ROM). This means that any of the interpreter’s default parameters that are changed using statusdict operators are not placed in nonvolatile storage and will not persist across power cycles. However, for parameters that are expected to change infrequently, a portion of RAM may be used to simulate EEROM.

Table 1-1 lists functional features of the LaserWriter Select 310 printer.
