The LaserWriter 16/600 PS was a high-end monochrome laser printer from the LaserWriter series that was released by Apple Computer in late September 1994, replacing the LaserWriter Pro 600 and 630.[1]


The 16/600 PS could print at a resolution of 600-dpi from a Canon LBP-ZX print engine that boosted output to 17 pages-per-minute with the same rated life of 450,000 pages as preceding models, but at the expense of higher power consumption.[2] It utilized FinePrint to adjust individual dot sizes to simulate smoother edges produced by higher resolution printers, though the improvements are reportedly imperceptible at 600-dpi. Upgrading the printer's RAM from the base configuration of 8 MB to at least 12 MB or more will enable PhotoGrade, which improves the printed appearance of grayscale images with finer halftones.[3]

The 25 MHz AMD Am29030 processor could rasterize images from PostScript Level 2 or PCL 5 printer data. The data could be transmitted through a LocalTalk network to its RS-422 serial port, or a direct PC connection to its parallel port. It also supports EtherTalk networking over its proprietary AAUI Ethernet port. A compact HDI-30 SCSI port could be used to attach an external drive to store additional fonts. An optional fax card can allow it to send, receive and print faxes.[2][3]

On June 15, 1996, the LaserWriter 16/600 was replaced by the LaserWriter 12/640 PS, which featured a faster 30 MHz AMD Am29040 processor. However, Apple switched from its usual use of a Canon print engine to a Fuji Xerox P893 mechanism that had the ability to print on both sides (duplexing) at the expense of sustained print speed.[4]

Legacy support[]

Apple phased out support for printing over the old AppleTalk-based EtherTalk protocol in Mac OS X 10.6 (Snow Leopard).[5][6] Printing over TCP/IP is possible, but this requires configuring an IPv4 address over EtherTalk by a Mac running Apple Printer Utility in classic Mac OS or the Classic environment.[7] The older LaserWriter Utility is only supported for Windows users, not Mac for this model.
