Printing bar codes
●
Bar codes are printed at 236 cps print speed when the printing density is 120 dpi or at 158 cps
print speed when the printing density is 180 dpi. (This does not apply to printing paths involving
HRI printing or duty control.)
●
Bar codes and normal characters are printed separately. When the bar code data
sequence start code is processed, print data other than bar code data contained in the
buffer is printed. When print data other than bar code data is input, bar code data
contained in the buffer is printed.
●
Like the right margin overflow processing for character data, data preceding bar code
data is printed and the bar code data is printed from the left margin on the following line
if the data exceeds the right margin.
If bar code data cannot be printed between the left and right margins, the bar code data
is ignored.
●
If the vertical line feed pitch is smaller than the bar code height, reverse feeding is
performed to move to the following printing position. (If an out-of-paper error is detected
in a bar code printing path, the following paths are printed on the following form.)
HRI
●
The HRI is adjusted to the center of the bar code symbol width and printed at 10 cpi
unless EAN or UPC guard bar expansion is executed. If EAN or UPC guard bar
expansion is executed, an HRI is printed at the equal space between the center guard bar
and the left or right guard bar.
If the HRI width is greater than the bar code symbol width, the HRI printing pitch is
reduced to print the HRI in the same width as the bar code symbol width.
●
The HRI is printed below a bar code symbol, the vertical printing position is lower than
the printing start position by (bar code height - 1/6”). If it is printed above the bar code
symbol, the vertical printing position is higher than the printing start position by (1/6” -
24/180”).
●
When Code 11 is selected, small triangle ( ) and large triangle ( ) are printed as the
start and stop characters, respectively. (This does not depend on the setting of the check
character.)
●
When Code 93 is selected, white squares (
) are printed as the start and stop characters,
and a black square ( ) is printed as the control character. A printable character
expressed in combination with the control character is printed as is. (For example, 61H is
printed as ‘a’, not ‘ A’.)
●
When Code 128 is selected, black rhombuses a (
◆
) are printed instead of non-printable
