Printronix ThermaLine Series - Manual (Page 133)

4–89 Commands
The default scale factor uses character row and column (6 lpi and 10 cpi).
Anytime CP.DP format (page 4–7) is used, the scale assumes 6 lpi and 10
cpi and a 60 x 72 dpi format.
You can change the Scale at any time during forms creation by using either
of the Scale commands. Elements designed before the scale change will
print at the former scale, while those elements following the scale change
will print at the current scale.
NOTE: Scale affects data position, not the printed data itself. For example,
alphanumeric data printed at 10 cpi will still print at 10 cpi after a Scale
change; however, where the data is placed on the page is affected.
Also, Scale affects line thickness if dot scale and horizontal/vertical scaling
are given.
