6.3 Exception Processing
6.3.1 Undefined codes
This term refers to the codes ranging from <00>H to <1F>H in the character code table. If
a code in this range that is not defined as a command is input, that code (one byte) is read
in and discarded, and subsequent data is processed as normal data.
Example: <30>H, <31>H, <03>H, <32>H, <0A>H, <33>H
If the above data string is input, the printer reads in and discards "<03>H" as an undefined
code. Note that <0A>H is defined as a command (
LF
). As a result, the data string that is
actually processed is: <30>H, <31>H, <32>H, <0A>H, <33>H
6.3.2 Undefined commands
If the data following
ESC
(<1B>H),
FS
(<1C>H), or
GS
(<1D>H) is not defined as a
command, then the two bytes (
ESC
,
FS
,
GS
and the code that follows) are read in and
discarded.
Example: <30>H, <1B>H, <22>H, <31>H, <32>H
If the above data string is input, the printer discards the data <1B>H and <22>H as
undefined commands. As a result, the data string that is actually processed is: <30>H,
<31>H, <32>H.
6.3.3 Settings outside the defined range
If a value outside of the defined range is input for a command that takes parameters, that
command execution is stopped and the previous value for that setting remains
unchanged. In the case of a command that takes multiple parameters, command
processing is halted the moment that a value outside of the defined range is input and
subsequent values are processed as normal data.
Example: <1B>H, <52>H, <15>H
If the above data string is input, <1B>H and <52>H are defined as a command (
ESC R
),
but the parameter <15>H is outside of the defined range. As a result, the printer reads in
and discards the data string <1B>H, <52>H, <15>H. Accordingly, the previously set
international character set is not changed.
6.3.4 Real-time commands
Real-time commands are stored after executing in the print buffer.
