I bought an unidentified Hercules mono graphic card on eBay.

But it has a db25 printer port.

In my system, it causes an error.

I want to turn off the printer port, but I can't find any data related to jumper setting.

Can you give me advice after looking at the picture?

Right to repair is fundamental. You own it, you're allowed to fix it.
