Chapter 8 — Print Unit
In many cases, it is desired to start the printing immediately at the top
of the label. Actually, what you want to do is to pull back the edge of the
media to the dot line. You can do this by means of a negative Start Adjust
value, for example -108 dots = 13.5 mm/0.53 inches for a 8 dots/mm
(203.2 dpi) printer. Be careful not to enter too large a value, or the media
may come loose from platen roller.
When using peel-off operation, the labels would drop from the liner and
get stuck on for example the desk if you use the default Start Adjust value
0. Use a Stop Adjust value of around -40/-60 (= 5.5 mm/0.22 inches)
instead: that is, after the printing is completed 5.5 mm/0.22 inches less
of media feed than normal will be performed. However, if you still want
to print from the top of the label, you must compensate by a Start Adjust
value of around -80/-115 (= 10.0 mm/0.39 inches).
A special case is tickets with black marks. It is recommended to place the
black mark adjacent to the perforation or the intended tear-off line. If the
black mark is placed further down the media, this must be compensated
for by a negative Stop Adjust setting.
