QL-500 Label Misaligned

[Flo2410]

Describe the bug I'm trying to print some labels with my QL-500 printer onto 17x54 mm die-cut labels. Unfortunately, the print does not align with the label itself, see picture below. Furthermore, the label gets pushed out too far, and cutting it cuts off a part of the next label.

The labels are generated by the label generator of PartDB. I'm printing via die KDE system dialog opened with floorp (firefox). The only label size which actually prints is the autogenerated custom_16.93x53.98mm, using the actual size of 17x54 mm results in the printer's power led flashing.

The exact same label works on Windows 11, printed directly via floorp.

To Reproduce Steps to reproduce the behavior:

1. Get the sample from below.
2. Try to print it.
3. The print is misaligned.

Expected behavior I expect the print to align with the label.
