5.6.2- Hexadecimal dump mode

To enter this mode answer NO to the previous question

"Enter in configuration?". It will be followed then by the question

"Enter hexadecimal mode?" to which YES must be answered.

Once entered this mode, which will be indicated by "***HEXADECIMAL MODE***" anything sent to

the printer will be printed as hexadecimal characters.

This mode can be very helpful for the application developer during the setup test time, as it allows

detecting possible errors (like out of range parameters, non valid command sequences, errors in the

communication channel, etc.), comparing what it has theoretically been sent to the printer to what it is

really being received.

Turn off the printer to quit the hexadecimal mode.

NOTES:

(1) For any received characters under 20h, the ASCII

'.' will not be printed.

(2) During the hexadecimal dump mode, the DEL EOT

command does not work.

(3) It must be taken into account that if the number of

bytes is less than the minimum amount required to

print one line (9 bytes), the printer will not print. It is

recommended to complete the hexadecimal dump

by sending at least 9 bytes (for example 00h).

(4) It is also possible to enter the hexadecimal mode

through the GS (A command.

5.7- ERROR PROCESSING

5.7.1- Error types

When an error occurs, the printer visually notifies its type through the LED. This fact allows the

final user to have a direct and visual reference of the current printer status.

On the other hand, the printer status and all its possible errors can also be monitored via software

through the DEL EOT command or activating the automatic status reporting (See section 6 –

CONTROL COMMANDS). In this way, the application developer can have more complete information

on the printer status, therefore being able to act accordingly.

The errors detected by the interface are the following: No paper / door open error, hardware error,

converter voltage error and printing head temperature error.

When any of these errors happen, the led blinks with a different blinking timing sequence and color

for each of them according to the figure below. If no error happens the led will light permanently green.
