Printing
Use the print button on the master scale when printing. If more than one scale is
being used, put the slave scale(s) in the total mode. This will allow the printer to print
the total weight of all the scales. The important thing to remember is that the
printer will print whatever is displayed on the last scale in line before the printer.
In addition to the weight, the printer will print a letter that signifies the number of scales
that it printed the weight from.
i.e. The letter A signifies the weight is from one scale. The letter B signifies the weight
is from two scales etc..
