Defining the Print Control PacketUse the print control packet (C) to set the contrast, print, and
margin adjustment, print speed, and printhead width.
Syntax {I,C,contrast,print_adj,margin_adjust,
speed_adj,ph_width p }
C1. C Print Control Packet
C2. contrast -390 to 156 (9403) or -699 to 699 (9825/985x/9860). 0 is the
default.
C3. print_adj -99 to 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 to 99 in 1/203 inch (or 1/300 inch for 985x/9860 printer).
0 is the default. Adjusts where data prints horizonta lly 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.
C5. speed_adj Print speed in inches per second (ips). Op tions:
0Default (formats with serial bar codes automatically
print at 2.5 ips)
20 2.0 ips (only speed for 9403)
25 2.5 ips (default for serial bar codes)
40 4.0 ips
60 6.0 ips (default for 9825/985x/9860)
80 8.0 ips (985x/9860)
100 10.0 ips (985x with 203 dpi)
120 12.0 ips (985x with 203 dpi)
NOTE: Serial bar codes with an 8-dot narrow element do not
automatically print at 2.5 ips. Serial bar codes
printed at speeds greater than 2.5 ips may not scan
properly. However, the 985x and 9860 printers can
print 203 dpi serial bar codes with narrow elements of
3 dots (or greater) at 4.0 ips. You must use a print
speed of 2.5 ips with the high energy ribbon. See
"Special Printing Considerations," in Chapter 6 fo r
more information.
C6. ph_width Width of the printhead in dots. Use 0 for these printers.
