ZG310 Thermal Printer User Instructions 15
5 Printer Operation and Programming
The ZG310 utilizes a Fujitsu FTP-628MCL103 printer mechanism, with a fixed
(parallel) print head with 384 horizontally-arranged thermal elements. The paper is
advanced by a stepper motor, and printing takes place in a single dot row for each step
of the paper. Each printed dot is approximately 1/8 mm square. The printing speed and
dot density are controlled according to the power supply voltage and the head
temperature.
Various printing modes, including graphics, are invoked by Escape sequences. Control
codes and status report protocols are described in detail in the Service Manual which
is provided separately.
5.1 Data Buffer
The ZG310 has a nominal 20k byte buffer to optimize throughput which enables data
to be received into the buffer while previous lines are being printed. Printing will be
initiated on receipt of a valid logical line of data or a complete graphics pattern.
The buffer may be cleared by data command or by a hardware reset. A partially full line
will be printed on receipt of an appropriate control code, or after a programmable
timeout delay.
5.2 Spool Mode
Spool mode can be entered by one of the following:
l
a command from the host
l
a paper out condition or head up condition being sensed.
l
an error condition (e.g. head over temperature, over voltage, etc).
In spool mode, the buffered data are stored without being printed until the mode is
exited by:
l
a command from the host.
l
a causing condition (e.g. Paper Out or Head Up) being cleared.
l
the paper feed button being double-clicked.
5.3 Character Printing and Fonts
The default 32-column character set is formed from a 24x10 dot matrix, and is based
on the industry standard IBM® character set Code. This character set has been
modified to include the Euro symbol ('€') at position 80H (128 Decimal), in place of the
usual capital C with cedilla ('Ç').
Various combinations of single or double width, single or double height, inverted,
underlined, and other attributes may be mixed within a line.
Customized fonts may be created using the Font Editor Utility, and downloaded to the
ZG310. Only a single custom font may be loaded in the printer at one time, and having
a custom font installed prevents the internal fonts from being accessed. Depending on
the attributes of the custom font, graphics operations may be affected.
