5. Bar code and enlarged character function
• Modulus 47
a. Data characters are weighed from the right to the left, as, for
example, 1, 2, ..., 20, 1, 2 ... 20, 1, 2 and so forth. The sum of
the data character values determined..
b. The character with a character value equal to the remainder of
dividing the value determined in step a by 47 is the first check
character (C).
c. Data characters are weighed from the right to the left,
beginning with C, as, for example, 1, 2, ..., 15, 1, 2 ... , 15, 1, 2
and so forth. The sum of the data character values is
determined.
d. The character with a character value equal to the remainder of
dividing the value found in step c by 47 is the second check
character (K).
• Modulus 103
a. The sum of the products of the data character values and
position values is determined. (The leftmost character has a
position value of 1.)
b. The start character value is added to the sum determined in
step a above.
c. The character with a character value equal to the remainder
of dividing the value determined in step c by 103 is the check
character.
After executing a BS command input immediately after bar
code data, printing starts from the position by one
character to the left of the currently set character pitch.
When a margin is specified, bar code data in the buffer is
cleared.
The element printing function prints bar codes by inputting
data element by element.
This function allows the user to print bar codes which are
not supported by the printer but are expressed by
combining elements. No HRI is printed, no check digit is
added, and a start or stop character is not added, since
data is input element by element.
The following show the codes expressing elements.
00H: Narrow bar
01H: Wide bar
02H: Narrow space
03H: Wide space
04H: Inter-character gap
