Specifying where to find the PCC byte within each print
record
The PCC byte must exist in a constant position relative to each print record. In the
majority of cases this will be the first byte of every print line.
If the PCC byte is not in the first byte of each print record, its position can be
specified in the ‘PCC Iden’ section of the View/Change PCC & Channel
Assignments dialogue.
Offset
The position of a PCC byte is specified as an offset. The
offset is the number of characters to skip in each print record
to reach the PCC byte.
The offset for a PCC byte is entered in the ‘Offset’ field in the
PCC Iden section of the dialogue.
Mask
It may be necessary to ‘mask’ a PCC byte, however this is
extremely rare.
The mask function will perform a binary ‘AND’ on the
decimal value of the PCC byte. The interpretation of the PCC
byte will be performed after adding the mask.
The mask for a PCC byte is entered in the ‘Mask’ field in the
PCC Iden section of the dialogue. The value is 255 which is
the same as adding ‘0’.
