PRINTER OPERATION AND PROGRAMMING

The DP-510 and DP-520 printers utilize 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 0.005" square. The printing

speed and dot density are controlled according to the battery 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 Programmer's Manual.

The printer has a nominal 20k byte buffer to optimize throughput: this 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.

Spooling mode can be entered by:

a command from the host;

Paper Out condition or Paper Lid open condition being sensed;

an error condition (e.g. head over temperature, battery over voltage, etc).

In spooling mode, the buffered data are stored without being printed until the mode is exited by:

a command from the host;

the 'causing condition' (e.g. Paper Out or Paper Lid open) being cleared;

the paper feed button being double-clicked.

The default 32-column character set is formed from a 24x10 dot matrix, and is based on the industry standard IBM®

character set Code Page 437. 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 a font editor utility, and downloaded to the printer. Only a single custom

font may be loaded in the printer at one time. Contact Dascom Technical Support for more information on the font

editor utility.

Various dot-addressable graphics modes are supported, at up to 384 dots per line. The Windows driver operates in

the graphics mode. Refer to the Programmer's Manual for full details of this and other advanced programming

modes.
