Hello devs!
I need orientation regarding a specific topic. I need to find a way to generate custom PDFs files on the fly using WordPress. The content comes from a db query and these values have to be inserted within a custom template.
I’m currently using the TCPDF library with my own custom plugin, but I keep getting weird errors (“Headers already sent”, corrupted files that cant be read except by firefox, completely blank files).
Is there a plugin or library wich does NOT require composer to be used?
Just to clarify, I do NOT want to convert a post or page to PDF (unless this helps me with my task).
Thank you in advance!

Are you trying to do this from inside WordPress? Do you only want the post content in the PDF, and not the header/footer?
You can definitely do this. A few years I wrote a plugin that added the ability to put /pdf at the end of a WooCommerce product URL and download a spec sheet for the product that was generated on the fly using a PDF template. Unfortunately I can’t find the code at the moment. 😩 I may have it on another hard drive. I’ll have to see if I can find it.
But, have confidence: you can definitely do it.
I think that issue means something is starting to communicate with the user’s browse before you try to generate/download the PDF. Since the PDF is a different mime type than an HTML page the process has to crap out. Have you tried googling “TCPDF headers already sent”?
