TSC TSPL TSPL2 Printer Programming

I'm wondering if there's a function, or at least the best way, to print on a 3 labels (column) per row paper such as this:

I'm asking because on the provided label design software (that came with the printer) I can input column count (along with paper & label size), and everything will print correctly.

While on TSPL's docs, I can't find anything on setup functions to input column count or paper size. Only label size which must be set up to cover the whole 3 column or it'll only print on the center label.

What I have in mind is to manually adjust the position before each output, placing them on the correct columns. I'm wondering if this is the best approach or not.

Thanks!

The easiest solution for such label printers is to use a .PRN (raw printer output) and modify it accordingly.

For a 3 labels per row, the easy solution would be to have all the elements replicated in the PRN 3 times and change the X coordinates for each element. Obviously, all the vertical commands (feed, gap, home) would remain the same as for a single label.

This solution works for any environment that supports copying a file to the printer.
