Since there is 15 different models, we would need to know which model
you are referring to but I took a chance and picked one model at random
and here are the results:

at 6 lines per inch (LPI) are shown as follows:

You would not use DDS to modify this but change either the printer
setup or do an OVRPRTF. Also bear in mind that when you change the
CPI there are default fonts that will change the appearnace of the
print. I would do several tests to get the desired results........
