The HP LaserJet 1020 Plus does not support macOS, only Windows and Linux. For some earlier macOS versions, an HP LaserJet 1022 Mac driver could be used for 1020 or 1018 models. However, it appears to be a problem installing such software under macOS Sequoia.
If a compatible HP driver cannot be found, or if another software solution is not possible, you may have to look for a workaround.
Linux drivers are available for the HP LaserJet 1020 Plus.

If nothing else helps, you could perhaps investigate whether a small Linux-based Raspberry Pi print server would allow a USB-connected HP LaserJet 1020 Plus to be shared with a modern Mac (or iPhone/iPad) in an AirPrint-like way. Look upon this as an experiment.
See, for example, the posts by Techguyuk about a Kyocera laser printer in Can’t print with iPadOS17 - Apple Community. Also, Tesserax reported about using a Raspberry Pi 3 Model B+ for an old HP LaserJet printer.
