For this printer, the resident fonts are Courier 10, Prestige Elite
12, Pica 10, OCR-B 10, OCR-A, Boldface PS, Compressed font,
Correspondence, and Draft. Unlike soft fonts, resident fonts
can always be accessed.
A type of serial interface. See Serial interface.
A test that determines whether the printer is working correctly.
Test pages are printed to show print quality and verify whether
all characters print. The self-test only tests the printer. It does
not test how thecomputer works with the printer.
A standard computer interface. Information is transferred
between devices over a single wire (although other wires are
used for control). A serial interface can use an interface cable
greater than 3 meters (10 feet). A long cable is often necessary
in networking environments, where the printer may be shared.
One of the printer’s two operating modes. In setup mode, the
control panel can be used to select the printer default settings,
such as print features, hardware options, and top-of-form.
Setup mode also provides some diagnostic functions. See also
Normal mode.
Shadow printing prints characters twice for emphasis.
Characters printed the second time are shifted slightly to the
right.
Single sheets are sheets of paper, envelopes, and noncontinuous
multipart forms fed into the printer using the paper table or
optional cut sheet feeder. Single sheets are also called cut sheets.
