Bar Codes
Minimum Error Correction- 0
This parameter is used to set the Minimum Error Correction level. This parameter must be
set to 0 for Auto if a non-Auto is selected for the size parameter.
Table 8-13
Mode - 0
This parameter is used to set the mode to be used in generating the QR code barcode. A
value of 0 generates a standard QR code while a setting of 2 would use the GS1
specification. Please note that if the GS1 is used, the application identifiers should be
entered with brackets, Example: [21]123.
8.2 Bar Code Rotation
When 0 and 180 degree bar codes are X multiplied (CMX), the space between characters is
also multiplied by the printer internally to maintain the correct ratio. When multiplying bar
codes use the default value for the spacing element (SP) in the field format parameters. On
some bar codes that allow spacing to be adjusted, spacing may be increased from the
default and not reduced to a smaller spacing.
When 0 and 180 degree bar codes are Y multiplied (CMY), the result is the actual height of
the bar code in thermal dots. If the Y multiplier (CMY) is not multiplied, a bar code with a
vertical length of one dot would be produced. For example: If a one inch high bar code is
desired using a 300 dpi print head, 300 should be inserted for the CMY value.
When 90 and 270 degree, ladder or vertical, bar codes are X multiplied (CMX), the result is
the actual width of the bar code in thermal dots. If the X multiplier (CMX) is not multiplied, a
bar code with a horizontal length of one dot would be produced. For example: If a one inch
wide bar code is desired using a 300 dpi print head, 300 should be inserted for the CMX
value.
