Problem
Barcode labels (digits) are not displayed in the deployed Docker container when "Label: ON" is enabled.
Root Cause
The base Docker image
mcr.microsoft.com/dotnet/aspnet:9.0doesn't include system fonts, which SkiaSharp requires for text rendering.Solution
Added installation of essential font packages in the Dockerfile:
fontconfig- font configuration systemlibfontconfig1- font configuration libraryfonts-dejavu-core- basic TrueType fonts
