Calibration info for LabelManager PnP, 12mm/9mm tape sizes

[maresb]

Here are three labels. The first one is a sample pattern with height 512 on 12mm tape. The pattern is truncated at row 64, so I conclude that the print head is 64 pixels high.

I measure the sample pattern to be about 8¾mm high.

The next two show the 64 pixel sample pattern on 12mm and 9mm tapes.

• 12mm

  • Top margin 1½mm
  • Bottom margin 1½mm

• 9mm

  • Top margin: 64th row is partially visible at the tape's edge
  • Bottom margin: 1st row is partially visible at the tape's edge

Is this all the info we need? @FaBjE, @tomek-szczesny, @tomers?

Yes, this is all the information we could possibly ask for. Looks way better than the original one. :)

h=512 obviously doesn't fit on the print, I wonder if there is anything we could do to preserve this information regardless of the tape size. How about repeating "h=xxx" across the full height of the print?

I could do that, but we're only going to do this a dozen or so times, and I don't want to go through the effort to recreate the photos yet again unless there's a really good reason. I'd say that simply not having h=xyz on the pattern is enough evidence that the pattern height is sufficiently large, especially since we don't actually care what h is.
