Specifications

r = Rows to Encode (“9” to “49”)
Odd values only for quality “0” to “140” (“10”-“144”);
even values only for quality “200.”
The number of rows and columns in the symbol will be
automatically determined. The user may wish to force
the number of rows and columns to a larger value to
achieve uniform symbol size. In the current implemen-
tation, quality “0” to “140” symbols will always be
square, so the larger of the rows or columns supplied
will be used to force a symbol to that size. If the user
attempts to force the data into too small of a symbol,
no symbol will be printed. If a value greater than “49”
is entered, the rows or columns value will be set to zero
and the size will be determined normally. If an even
value is entered, it will generate an “Invalid_P”
(invalid parameter). If a value less than “9” but not
“0”, or if the data is too large for the forced size, no
symbol will print; if ^CVY is on, INVALID - L will
print.
Quality “200” symbols may be adjusted by the printer
to a size that is different than the forced value.
