Never encountered paying for non-open access publication. I have only encountered "article processing fees" in relation to open access publishing.

If you're okay with having your paper paywalled, you do not need to pay for journal publication.

So I'm curious in which domain/subdomain you have encountered this.

In my area of semiconductor engineering/ detectors, we generally have to pay to publish. Journals do seem to be slowly moving away from this for just the publication, however as you say for open access you still need to pay. Depending on the funding provider for the research, it can be compulsory for the papers to be open access, so we would end up paying anyway.
