Rpi stock issues are well behind us. You can buy them straight up now. Even the 1GB RPi4.
Esp32 may not have enough RAM to buffer large prints, especially if there’s a lot of graphics. It is possible to give it up to 4MB of external RAM, but that’s still not much.
Pi Pico can do a 16MB external RAM chip. That’s starting to be adaqute.
I had an HP 5si for a while with 20MB of internal RAM. It struggled with Postscript printing–could only buffer and print one page at a time. Did fine with HP’s own PDL drivers, though.

I still had some trouble getting the Zero 2Ws, but a lot of sellers still have a limit of 1 per order.
I’ll probably use my Zero W for the print server once I replace the controller for my snake’s enclosure with a 2.
