[Caution] •When data being held in the print buffer, this command is ignored.
•Regardless of the specified feed pitch, this command feeds the paper to be required to
print a bar code.
•If the character code d cannot be printed in the respective bar code system, the bar code so
far will be printed, processing the subsequent data as normal data.
•When a bar code whose number of characters to be printed is fixed has been selected, the
number of characters k have to be always made equal to the number of characters to be
printed. (The bar code is not printed when not matching.)
•When the horizontal direction exceeds one line length, the excess part is not printed.
[Default] •The initial value is not specified.
[Description of Bar Codes] <For print examples, see Page 72.>
UPC-A This bar code, consisting of numerals only, has a fixed length of 12 columns; a 11-column
number entered from the host or application software plus a check column(12th column)
automatically calculated inside the printer. If the 12th-column numeral is sent from the host,
the entire bar code will be printed as it is.
UPC-E This bar code, consisting of numerals only, has a fixed length of 8 columns; the first number
system character is "0" stationary. A 12-column numeral entered from the host or application
software is compressed to 8 columns with a check column and printed. The 12th-column
check column is automatically calculated inside the printer and sent from the host, the entire
bar code will be printed, compressed to 8 columns.
JAN-13(EAN) This bar code, consisting of numerals only, has a fixed length of 13 columns; a 12-column
number entered from the host or application software plus a check column(13th column)
automatically calculated inside the printer. If the 13th-column numeral is sent from the host,
