Header Elements - Microcom 334M Operator's Manual

Designing Labels with LDS
The values for header elements requiring measurements are expressed as thermal dots or
pixels. Dot or pixel size varies depending upon the print resolution of the print head. Two
print resolutions are currently available for the 334M printer (203 DPI and 300 DPI). The dot
size of a 203 dots per inch head (8 dots/mm) is 0.0049". The dot size of a 300 dots per inch
head (12 dots/mm) is 0.0032". The dot size is the same in both the horizontal and vertical
direction. For example, a 4" X 6" label printed with a 203 DPI print head would be 812 (4 X
203) dots in the horizontal or "X" direction, and 1218 (6 X 203) dots in the "Y" direction.
While the maximum number of dots in the horizontal or "X" direction is limited by print head
size, it is virtually unlimited in the vertical or "Y" direction. Vertical dot rows are "stepped" by
the drive roller motor.
