Hi Ralph W. – Based on the additional details provided above, did you have any further suggestions we might be able to try to resolve our Win11/HTB2021 LPT1 printing issue with our existing code? NET USE LPT1 was implemented and didn’t resolve the issue. Also, confirmed that the printer pooling setting was checked under printer port settings. It doesn’t appear to be a permissions issue either, as we get the same error when logged in as an administrator.
Thanks, Seth A.
