I can't find the serial number label on my printer.

[PaperBoy68]

I checked the list of printers that are compatible with Win. 11 but my particular model was absent.
I tried to contact customer support about this, but I cannot find the serial number label anywhere on it.
I used the HP Print and Scan Doctor when searching for drivers and it listed the S/N, but when I enter it the website tells me to enter a valid S/N. I tried to go through the virtual assistant but shortly after initiating my session, It told me that the Bot can't talk right now, and supplied an error number. I am just about at my wit's end with this POS!
Where in the hell is the serial number?😠

The serial number should be on the bottom of the printer. That printer model is way too old to be supported in WIN11.
