Color LaserWriter 12/600 PS Basics & Theory 1–6

Speciﬁcations

Marking

Engine

Canon HX LBP print engine

• 3 ppm in color; 12 ppm in black, cyan, magenta, or yellow; 1 ppm

for transparencies

• 600x600 dpi with Color PhotoGrade

• Enhanced 600 dpi grayscale imaging (effective 200-line screen half-

tone, 122 gray levels)

Laser

Semiconductor laser GaAlAs

• Wavelength: 780 nm

• Output power: 1 mW

Controller

The speciﬁcations for the I/O controller board are as follows:

• AMD Am29030 30-MHz microprocessor

• 8 MB of ROM (including 39 Type 1 fonts)

• 12 MB of RAM (16 MB on CLW 12/660); 8 MB soldered + 4 MB

(or 8 MB) SIMM

(expandable to 40 MB total)

• 128 K parameter SRAM

• SCSI interface for internal/external hard disk(s)

• LocalTalk interface

• High-speed parallel interface (IEEE P1284 ECP, bidirectional)

• Ethernet interface with three protocols: EtherTalk, Novell NetWare

IPX (PSERVER or RPRINTER), and TCP/IP (BSD lpd)

• External Ethernet transceivers available for thin coaxial, twisted pair

(10Base-T), and thick coaxial (IEEE 802.3 AUI)

• Two-position communication conﬁguration switch

• All ports/protocols simultaneously active

• Color-rendering acceleration

• Data compression/decompression system

• Adobe PostScript Level 2 (version 2014)

True 600 dpi

The Color LaserWriter 12/600 PS is a true 600 dpi printer because

every aspect of its architecture is designed to a 600 dpi speciﬁcation. In

addition, its 8-bit per pixel capability can assign levels of color or gray

to each pixel, thereby further enhancing print quality.
