Expanded character rotation

n = 'a0' or 'A1

'Upright (preset)

n = 'a1' or 'A1

'Rotated 90 degrees

n = 'a2' or 'A2

'Upside down, rotated 180 degrees

n = 'a3' or 'A3

'Rotated 270 degrees

Bar code data start

n = "b" or "B"

Data that follows 'b' or 'B' is read in as bar code data.  Bar code data 
must end with the ' \ ' code (5CH), which also ends this command.  
The acceptable bar code data is determined by the bar code mode 
selected by 't' or 'T'. 

■

When CODE 39 is selected with the parameter 't0' or 'T0'  

Forty three characters '0' to '9', 'A' to 'Z', '-', ' . ', '  (space)', '$', ' / ', '+', 
and '%' can be accepted as bar code data.  Other characters will  
cause a data error.  The number of characters for bar codes is not 
limited.  The bar code data automatically starts and ends with an 
asterisk ' * ' (start character and stop character). If the received data 
has an asterisk ' * ' at the beginning or end, the asterisk is regarded 
as a start character or stop character. 

■

When Interleaved 2 of 5 is selected with the parameter 't1' or 'T1':  

Ten numerical characters '0' to '9' can be accepted as bar code data. 
Other characters cause a data error. The number of characters for 
bar codes is not limited.  Because this mode of bar codes needs even 
characters, if the bar code data has odd characters, '0' is 
automatically added to the end of the bar code data. 

■

When FIM (US-Post Net) is selected with the parameter 't3' or 'T3'  

Characters 'A' to 'D' are valid and one digit of data can be printed. 
Upper-case and lower-case alphabet characters can be accepted. 

■

When Post Net (US-Post Net) is selected with the parameter 't4' 
or 'T4'  

Numbers '0' to '9' can be data and it must end with a check digit. '?' 
can be used instead of the check digit.
