The LaserWriter is a series of laser printers from Apple Computer.

LaserWriter 4/600 PS

The LaserWriter 4/600 PS printer is a mainstream network laser printer designed for the small-business market. Replacing the Personal LaserWriter 320, it supports PostScript Level 2 functions and produces up to four printed pages per minute. The LaserWriter 4/600 PS printer has improved imaging capabilities and supports 600-dpi (dots per inch) resolution. Using Adobe Memory Booster Technology (AMBT) it accomplishes this with only 2 MB of DRAM.

LaserWriter 12/640 PS

The LaserWriter 12/640 PS printer is a mainstream network laser printer designed for midsize to large businesses, higher education institutions, Macintosh and non-Macintosh networks, and graphics and desktop publishing environments. It supports Adobe PostScript Level 2 programming functions and produces printed pages at a rate of up to 12 letter-size pages per minute. The LaserWriter 12/640 PS printer supports 600 dpi resolution. FinePrint can be selected to smooth text and line art. FinePrint technology gives the printer the ability to print dots of different widths, producing crisper text and graphics.

The printer also supports PhotoGrade printing. This is a technology that enables the LaserWriter 12/640 PS printer to print photographs with as many as 97 shades of gray. PhotoGrade can designate more than one level of gray for each pixel by controlling the size of the dots. Photographs printed using PhotoGrade technology retain a higher level of detail than that achieved by other 600-dpi laser printers. You need a minimum of 12 MB of DRAM, implemented by the 8 MB DRAM update, to support this feature.

The LaserWriter 12/640 PS printer comes with 4 MB of DRAM installed in one of its two SIMM slots. You can expand DRAM capacity up to 64 MB by using higher capacity SIMMs and populating both slots. The LaserWriter 12/640 PS has separate controller systems for imaging and I/O processing. The imaging system uses an AMD AM29040 processor, and the I/O processing system uses an 80C186 embedded processor. The imaging and I/O systems share messages and data through a shared SRAM (static RAM).

LaserWriter 16/600 PS

The LaserWriter 16/600 PS printer is a mainstream network laser printer designed for midsize to large businesses, higher education institutions, Macintosh and non-Macintosh networks, and graphics and desktop publishing environments. Replacing the Apple LaserWriter Pro 630, it supports Adobe PostScript Level 2 programming functions and produces printed pages at a rate of up to seventeen letter-size pages per minute.

The LaserWriter 16/600 PS printer supports 600 dpi resolution. FinePrint can be selected to smooth text and line art. FinePrint technology gives the printer the ability to print dots of different widths, producing crisper text and graphics. Antialiasing smooths the jagged edges of both characters and lines, producing an effective resolution much greater than 600 dpi.

When configured with 12 MB or more of RAM memory, the LaserWriter 16/600 PS printer also supports 600 dpi PhotoGrade printing. Photograde technology allows the LaserWriter 16/600 PS printer to print photographs with as many as 97 shades of gray. Photographs printed using PhotoGrade technology retain a higher level of detail than other 600-dpi laser printers are capable of producing. PhotoGrade can designate more than one level of gray for each pixel by controlling the size of the dots.

LaserWriter Pro 600 & 630

The LaserWriter Pro 600 and 630 printers are the next-generation replacements for the LaserWriter II printer. They provide higher print quality, better performance, a wider range of interfaces, and improved paper handling, at a lower cost than the LaserWriter IIf or the LaserWriter IIg.

LaserWriter IIg

As of this writing, the Apple LaserWriter IIg printer is the most powerful and most capable LaserWriter every built by Apple. The LaserWriter IIg is an expandable network printer that makes use of PhotoGrade technology. The unit can print images with more than 65 levels of gray and is capable of smoothing jagged edges by using its FinePrint technology.

LocalTalk capabilities allow for plug-and-play simplicity when connected to an AppleTalk network. The LaserWriter IIg has built-in Ethernet features for easy connection to high-speed EtherTalk networks. The unit can be connected simultaneously to Ethernet, LocalTalk, and other serial interfaces. The LaserWriter IIg can be connected to multiple types of computers or networks.

Incorporation of a high-speed controller and Adobe's PostScript Level 2 software results in document printing at a speed of up to twice the speed of the LaserWriter IINTX. The newest generation of PostScript improves printing speed and adds new capabilities over previous models, and is fully compatible with existing applications and drivers. The IIg is also compatible with the Hewlett Packard LaserJet IIP (PCL 4+) emulation software.
