Both IMZ220 and IMZ320 printers have the same resolution value, which is equal to 203 dpi. So they should have no any difference between amount of lines can be printed on a label.
However, due to different printing width there could be a difference in case you are printing your labels as 90 degree rotated. Their printing widths related to each other with ratio 1.5. In this case you may have an coarse idea on new value in a following way:
new_value = old_value * 1.5
