P 190

Forward feeds (n) lines
The command $0B forward feeds the printer by the number of lines previously set. This must be an
ASCII number from 0-9; obviously if the number is zero, nothing will happen. Take care because the code
$0B erases the line buffer and so, if there are any characters in it, they will automatically be erased. If, for
example, you want the paper to forward feed by 5 lines, transmit:
$35 $0B (or, alternatively, 5 and the command $0B).
ASCII: - Hex: $0D
Prints line buffer
The command $0D (carriage return) prints the line buffer. If the buffer is empty, nothing happens. If the
CRLF option is set, the code $0D is ignored and printing only takes place if the command $0A is
transmitted. When the printer is switched on, the default value of the CRLF option is contained in the
flag of a byte called “option register” which can be manipulated through the configuration by using the
two keys on the front panel of the printer or through the programme from the PC.
ASCII: - Hex: $0F
Sets CRLF mode
The command $0F enables the CRLF option. It inhibits the action of the command $0D, and keeping
only the command $0A as a print command. This function can be useful in cases where the RETURN
key is associated with the $0D and $0A commands, thus causing the P 190 to print in double spacing.
To disable this option, the printer has to be reset, either by switching it off or by transmitting the reset
command. When the printer is switched on, the default value of the CRLF option is contained in the flag
of a byte called “option register” which can be manipulated through the configuration by using the two
keys on the front panel of the printer or through the programme from the PC.
ASCII: - Hex: $11
Graphic mode
The command $11 enables the P 190 printer graphic mode, i.e. to print in graphic mode transmit the
commamd $11 at the beginning of each line. One line for the P 190 printer (24 column model) corresponds
to 144 horizontal points divided in 24 6-point blocks. For the P 190 printer (40 column model) one line
corresponds to 240 horizontal points divided into 40 6-point blocks. For byte format in graphic
configuration, see paragraph 4.2 (Graphics).
ASCII: - Hex: $12
Prints the time and date
This command prints the time and date in the following format:
hh : mm dd - mm - yy
If the expanded or double width formats are selected (i.e. with less than 15 characters per line), only the
time will be printed. If seconds printing is enabled, the format will be:
hh:mm:ss dd - mm - yy
In any event this command resets the line.
ASCII: - Hex $13
