B5. supply_posn -99 - 99 in 1/203 inch. 0 is the default. Adjusts the machine
to print at the vertical 0,0 point on the supply. This
adjustment accounts for mechanical tolerances from machine
to machine. The supply position adjustment only needs to be
made on the initial machine setup. Adjust the supply position
if formats do not start at the 0,0 point on the supply. Increase
the supply position to move print up, decrease to move print
down on the label. To verify the 0,0 point, print the diagnostic
labels. See Chapter 8, "Troubleshooting," for more
information. You can’t change the supply position while the
printer is active. Changing the supply position will affect the
print position, dispense position, and backfeed distance.
Once the supply position is set, use the print control packet
and backfeed control packet to adjust printing and the
dispense position.
Example
{
I
,B,0,0,1,10
p
}
Indicates black mark and thermal direct stock has been loaded,
causes the printer to operate in on-demand mode (purchase
optional), and feeds the supply approximately .05 inches up
before printing the format on each label (10/203 inches).
Defining the Print Control Packet
Use the print control packet (C) to set the contrast, print, and
margin adjustment, print speed, and printhead width.

C2. contrast -28 - 40. 0 is the default. You may need to adjust this value
depending on the type of supplies you are using. For
example, linerless supplies require a higher print contrast, but
receipt paper requires less contrast.
C3. print_adj -99 - 99 in 1/203 inch. 0 is the default. Adjusts where data
prints vertically on the supply. Increase the print position to
move print up, decrease to move print down.
C4. margin_adj -99 - 99 in 1/203 inch. 0 is the default. Adjusts where data
prints horizontally on the supply. Increase the margin position
to move print to the right, decrease to move print to the left.
Margin and print position are format adjustments. They will
not affect the supply position, dispense position, or backfeed
distance.
