TSC TSTP-225 ПРИНТЕР МАКТЕР НАБЛЮДАЕТСЯ только на первом печати из приложения .NET 8 Console

Описание:
У меня есть приложение .NET 8 C# Консольное приложение, которое печатает метки с использованием принтера TSC TTP-225 через команды RAW. При первом исполнении печатная метка имеет неверные координаты, вызывая смещение. Однако, если я немедленно запускаю приложение снова, метка отлично напечатает без каких -либо проблем.
