f = 2 link watermark printing
Example:
Activate watermark printing using logo #F1 (1F 03 16 02 s r) with “s” being the skip distance in dot rows before
activation and “r” is the distance in mm between watermark repetitions.
After executing a knife-cut command and the f = 1 steps, if s > 0, execute the following:
• skip “s” (feed paper) dot rows (15 s command)
• set watermark printing to “on” using logo F1 (execute merge watermark mode -1D 8C r F1 command). Logo must
be defined for F1 and comply with watermark mode requirements in order for this happen.
• stop background merging mode (1D 9B 1 command). Clears background for logos, barcodes, and captured images.
The watermarks feature is now activated (following an optional F0 logo) to start after each knife cut. Note that
when printing graphic objects, merging is turned off by each knife cut. The default value is s = 0 and turns off the
f = 2 watermark link.
No correlation exists (when both are set) between watermark and logo skip distances.
If the f = 4 logo link is undefined, you should set a null trailer logo with s = 1 and p = 144 (1F 03 16 04 1 90, no
logo at index F3). This will turn off watermarks at the position of a knife cut and leave a clear space at the top of the
next receipt.
f = 3 link margin message printing
Example:
Activate margin message printing using logo #F2 (1F 03 16 03 s r t) with “s” being the skip distance, “r” the
distance between repetitions and “t” the toggle mode.
Toggle mode values for t:
0 = both left and right side
1 = toggle sides, starting with left side
2 = right side margin message only
3 = left side margin message only
After executing a knife cut command and the f=1 steps, if s > 0, execute the following:
• skip “s” dot rows (=15 s command). When both watermark and margin message merging are defined, the
respective “s” values are treated independently. The same value should be used to start watermark and margin
message at the same place.
• Use the toggle mode values listed above to apply margin message for the left and/or right side. For margin
messages on both sides, enter the 1D 99 1 F2 p 0 command followed by the 1D 99 t’ F2 r t’ (apply margin
message) command with the message at index F2 defined.
• suspend background merging mode (=1D 9B 1 command), so any logos, barcodes, and captured images will print
in the clear.
The margin message printing feature is activated after the header logo after a restart at each knife-cut. Note that
when printing graphic objects, merging is turned off by each knife cut. No correlation exists (when both are set)
between watermark and logo skip distances.
If the f = 4 logo link is undefined, you should set a null trailer logo with s = 1 and p = 144 (1F 03 16 04 1 90, no logo
at index F3). This will turn off margin message at the position of a knife cut and leave a clear space at the top of the
next receipt.
