I have yet to have a PDF version of a W9 form allow me to fill it in completely without telling me some portion of the thing will not allow a text field and/or signature. It's a real fucking pain in the ass, is what it is.
I am having this exact problem, despite being trained to create fillable forms in Acrobat. I could FIX it if they weren't locked, but they're all locked. This is insane.
There have been a few of these where I've printed the form out, scanned it, and then turned the scan into a fillable form. This tactic is normally reserved for things like authorizations to share medical data, where I'll have to turn in multiple versions (one for each provider).
I print the PDF to PDF in the first step, rather than onto paper. Using the "Microsoft print to PDF" option has much the same effect as the print-and-scan method, but faster and with fewer printer artefacts and slightly wonky pages.
Today I discovered that some recent changes to my account seem to have removed Microsoft Print to PDF from my available options. I am now sad and have a much longer workflow.
