Printronix SL4M Reference Manual page 63

NOTE: 1. Multiple RFRTAG commands are allowed in the same
form but the same DFn field cannot be defined multiple
times.
2. The DF field length is restricted to 64 bits for binary or
decimal format and must be a multiple of 8 bits. The sum of
all field lengths must be equal to the tag size.
3. The first field always start at the MSB bit. The bit length
of a field dictates the start bit of the next field, etc. As a
result, DF fields will not overlap each other.
4. RFRTAG does not allow incremental fields (with the "I"
prefix).
5. 432 IGP dots in the ~CREATE line specifies a 6 inch
label. 6 inches = 432 (IGP dots)/72 (dpi)
Use 144 for 2 inch labels and 288 for 4 inch labels.
Example
Same as Example 4 on page 57, except the increment
is dynamic and the result is merged into Alpha to print
on the smart label.
