A more serious answer - it depends greatly on where I'm working and what we're doing.

I've worked in places where we'd receive outsource work. Usually we'd get fairly detailed instructions about what to do and what to avoid, that were discussed between our PMs/architects and the client, including tests for example that were agreed upon. You were supposed to follow those to the letter, but the most important part was that you needed to deliver quickly because the customer wanted to keep costs to a minimum. "Useless questions" (from their perspective) were seriously frowned upon, so if it wasn't specified, the expected approach was to do whatever was quicker.

This occasionally lead to situations where their QC/UATs would identify issues with their business rules, but as long as it was compliant with the requirements we received, it would then come back to be changed (at additional cost, depending on how big the change needed to be).

Once accepted though, job done, grab your next work item and move on. Months later they could run into a situation like the one in the printer and come back asking for a fix, but very likely that would go into the CR bucket and a quote would be provided.

Of course if you're working for a company that actually cares about what they're building, the philosophy is completely different. If I'm working on our products, then I build a good understanding of what I'm working on, and I'm expected to flag any concerns or issues I encounter even before it reaches QC.

That said, I've never heard of a developer ever being criminally charged other than intentional misconduct - like, in the world. Look at the IBM Queensland Health payroll system fiasco, I'm not sure anyone was even fired, let alone prosecuted.

Or even the Boeing 737-MAX crashes - how do you build a system that pitches the nose down repeatedly, without limitations? Those guys who worked on the MCAS software would 100% have considered a scenario where an angle-of-attack sensor would provide bad data, and the consequences of repeated trim, but alas - 2 planes crashed, 350 people died, and what are the consequences? Some payouts...
