GCC Printers Elite 12ppm - Manual (Page 185)

J-7
resolution: The number of dots per unit of length or area. Higher resolution usually leads
to better image quality. High resolution pages typically have sharper text and more detailed
photographs than low resolution pages. High resolution pages may require more RAM to
print than the amount supplied in the printer.
RAM (Random-Access Memory): Temporary storage area for information. This informa-
tion is lost every time the computer or printer is shut down.
ROM (Read-only Memory): Permanent storage area for information. This information is
usually supplied by the manufacturer of the computer or printer and is not accessible by
the user.
RS-422: An 8-pin hardware interface that allows the transfer of data in an asynchronous
serial format. It has five user-defined parameters: baud rate, data bits, stop bits, parity, and
flow control. Your GCC printer’s RS-422 interface is shared with the LocalTalk interface.
screen fonts: Fonts displayed on the Macintosh screen; they’re represented on paper with
printer fonts. Screen fonts are not as high quality as printer fonts; if you don’t install the
printer fonts the printer will print the screen fonts.
screen frequency: The number of lines of dots per unit of length in a halftone screen.
SCSI: A standard for transmitting data. While often used to connect devices to computers
(particularly Macintoshes), it is used by GCC printers to optionally connect hard drives to
store fonts and other information. It is not used to connect the printer to the computer.
The SCSI chain on a printer is totally independent of any SCSI chain on the computer.
serial: A way of transmitting information one bit at a time. Serial transmission of data to
the printer is usually slower than parallel printing.
sheet feeder: An additional paper source. It requires a paper tray to actually hold the paper.
simple page: A page purely consisting of text.
star network: A form of networking where each computer is connected to a hub, and all
network traffic flows through the hub.
stop bits: The number of bits that specify the end of a serial transmission frame.
straight through paper path: A way of passing paper through the printer without it bend-
ing. Sometimes heavy or easily damaged paper can only be printed this way. Usually set up
by using the multipurpose feeder and a rear output tray.
smoothing: A process that makes the text and graphics of some applications look better.
startup disk: The disk (usually a hard disk) containing the System and Finder files used to
run the Macintosh.
