What, exactly, does the "Tape" dropdown set?

[fake-name]

Thank you for this tool. One thing you might not be aware of is that the p-touch cube will happily print on heat-shrink tube labels with this tool. Apparently the limitation of requiring a much more expensive label printer to print on heat shrink tubing label stock is entirely in software!

That said, I'm somewhat confused by the UI entry to set the tape type. Setting it to TZe-S211 (the closest in width to HSE211e) doesn't seem to set the margins correctly at all.

I can work around the issue by just manually fiddling with the margins, but is that just not something that setting the tape variety does? I can't see why there'd be multiple entries of the same color combination unless it does something in addition to just changing the preview colors.
