programmable character. In fact, it is possible to programme two characters which can be printed at any
time with the codes $1E and $1F. There are two ways of programming the characters; the can be saved in
a non volatile memory which stores all the data, even when the printer is switched off, or alternatively, in a
memory which is automatically erased when the power is switched off. In the first case, the user can ask the
technicians responsible to programme the two characters, depending on his requirements, or the user
himself can programme the by using the personalized software supplied by Custom Engineering. In the
second case, the user can form the characters at the same time as he is transmitting the text to be printed;
the advantage of this approach is that an infinite number of symbols can be associated to a character,
exactly as the user pleases, which he can print and modify as he sees fit. If the printer is new (or if the
characters have not been manipulated), the following symbol | | | will be associated with codes $1E and
$1F; each time the printer is switched on, the above mentioned codes will contain the last characters
programmed in the non volatile memory.

Prints the 1st (...8th) programmable character (software release 5.3)
If the hexadecimal character $17 (...$1F) is transmitted to the P 190 printer, it will print the corresponding
programmable character. In fact, it is possible to programme eight characters which can be printed at
any time with the codes from $17 to $1F. There are two ways of programming the characters; they can
be saved in a non volatile memory which stores all the data, even when the printer is switched off, or
alternatively, in a memory which is automatically erased when the power is switched off. In the first
case, the user can ask the technicians responsible to programme the eight characters, depending on
his requirements, or the user himself can programme them by using the personalized software supplied

mentioned codes will contain the last characters programmed in the non volatile memory.

Sets the printer in reverse mode
The command “ESC” R selects reverse mode printing. In reverse mode printing, the ticket comes out
of the printer with the writing right side up and running from left to right. When the printer is switched on,
the default value is selected by the flag of a location called the “option register”; this flag can be
manipulated by programming, using the the two keys on the front panel of the printer with which the
default value can be changed and it can be decided whether the printer is to be in reverse or normal
mode when it is switched on.
