Escape character:
The escape character E
C
is always entered
before an instruction in ASCll code. This
character is not printed, but the printer
recognizes the following characters as
instruction code.
Escape sequences:
See Printer instructions.
Face thickness:
This refers to the width of the character
strokes. It can be either regular or bold.
Font:
A font is a collection of characters and
symbols of the same font type and spacing,
the same size (height), face thickness and
style. Fonts may be installed internally in the
printer or be loaded externally from font
cartridges.
Font cartridges:
These contain fonts that can be loaded into the
printer.
Font style:
The font characters can be printed either in
regular script or in italics with a constant angle.
Font type:
The font type refers to the design of a
character set. Thus Cour has a different
design than LetGot or Helv.
Handshake:
The handshake controls the data transfer
between computer and printer. It is designed
to protect the printer buffer from overflow or
data loss.
Hardware:
This term covers the physical parts of your
computer system such as the computer itself,
the keyboard and the printer.
Installed fonts:
The internal fonts are installed in the printer
and are an integral part of it.
Interface cable:
The data transfer cable that links your
computer to the printer or another peripheral
instrument.
Interface connecting socket:
The DA608 is supplied with two interface
sockets, one parallel and one serial. Both are
located under the paper feed container next to
the power module. The cable connecting your
computer and printer is plugged in here.
LPI
Lines Per Inch. This is the unit of measure-
ment for the line density. The most frequent
setting for printing is 6 Ipi.
Off-line:
When off-line, the printer cannot receive any
data from the computer. In this mode, settings
and programming steps are performed on the
printer itself.
On-line:
When on-line, the printer can receive data
from the computer. The keyboard is then
unresponsive except for the "START" key.
Paper detection:
This sensor is necessary for maintaining the
top margin value and for stopping the printer in
the event of a paper jam. The paper must
always pass over the paper detection device.
Paper jam:
A paper jam occurs when the paper gets stuck
during printing. Both paper feed and ejection
are then blocked.
Paper size:
This refers to the format of the paper that is
being printed. When the address block is
rotated by 180°, the top margin is
automatically modified so that it corresponds
to the value set for the normal orientation of
the address block.
Parallel interface:
This is a connection between the computer
and printer. It is also known as a Centronics
interface. The data is always transferred as a
single byte (= 8 bits) at a time (in parallel).
Parity:
This is an error detection technique that is run
via a serial interface. Errors in the transfer
procedure are detected during data transfer. A
check is made to ensure the evenness of
binary ones in an information unit (e.g. a byte).
PCL instruction:
PCL = Printer Control Language is the HP PCL
level III printer language that was developed
by Hewlett Packard.
Pitch:
This refers to the number of printed characters
contained within an inch.
Print area:
This refers to the maximum range reachable
by the cartridge.
Printer driver:
This converts the printer instructions entered
via software to instruction codes for the printer.
The printer driver must be matched to both the
software and the printer.
Printer instruction:
This is entered via the software application in
order to make changes in the active printer
configuration.
