fitted inside the printer in the line buffer. This command can be used for entering the date in the context of
a sentence without zero-setting the line buffer. If, for example, you wish to write:
DATE : 09-11-93 TEST OK
you will send: DATE : $1B$55 TEST OK $0D
If you only wish to print the date, it is enough to transmit $1B$55$0D. The date is transmitted in 8
characters and, if the seconds option is enabled in 8 characters; if there is not sufficient space left in the
line buffer, it is not printed.

Enables the printing of seconds
The command “ESC” S enables the printing of seconds when the time is requested with command
“ESC” T. When the printer is switched on the default value, which determines whether or not the
seconds are to be printed, is contained in the flag of a byte called the “option register”; this flag can be
manipulated by programming, using the the two keys on the front panel of the printer.

Transmits operating hours in serial
The command “ESC” O (option of software release 5.3) transmits the total operating hours of the printer
to the serial port. These hours are allocated in the battery-driven RAM of the Real Time device fitted
inside the printer. If, therefore, there is no Real Time Clock, this command will produce no effect. In
addition, if the user utilizes the parallel port, the operating hours will not be transmitted since the parallel
port is unidirectional. The hours begin to increase as soon as the printer is switched on. The increase
is, in actual fact, on a minute to minute basis but the printer only counts the completed hours. The
transmission format is in ASCII standard and four characters are transmitted: in order of importance.
The transmission protocol is the same as that set by by the user on the serial interface. As there are four
characters it can reach a maximum of 9999 operating hours; it then automatically zero-sets and continues
counting.
ASCII: ESC T Hex: $1B $48
Zero-sets total operating hours
The command “ESC” T zero-sets the printer’s total operating hours. If you are using the total hours
option, it is advisable to use this command immediately after switching on the printer so as to synchronize
the operating hours of the printer itself with those of the master device.
