Your post is in the wrong forum since you are selling a product...so it will be considered SPAM.
That aside...your screen shots only show one style of PB...so how does your software work for all the different styles/sized of PBs out there AFA properly spacing the text?
I use narrow, 3-row TT bays, and unlike the ones shown in your screen shots, they don't have all that spare room above the points for labels...there are only thin, plastic covered "channels" for adding labels.
TO tell the truth, I can get more mileage out of a typical Brother laser label maker. Not as much font/color options, but it works.
