When dragging these to the /Library/Printers/ folder and trying to add the printer in System Preferences, you may get a message that the printer drivers need repairing in order to make the printer work. I have uploaded the HP Printer Drivers for the Laserjet 1018-1020-1022 here, which is a much smaller download and cuts out all the stuff you don't need. You can copy these into your /Library/Printers/ folder. Once you've expanded the first PKG file, you'll get another folder with the same file (HewlettPackardPrinterDrivers.pkg), run the same command on this file, and it'll give you all the files you need. Pkgutil -expand PATH-TO-PKG-FILE PATH-TO-EXPAND-TO Open the DMG file and mount it, then go to Terminal and use this command to extract the PKG files: HP Laserjet 1010 / 1012 / 1015 Windows XP/Vista/7/8/8.1/10 (32/64-bit) Mac OS X 10.13 - 10.6. On Big Sur (M1 or Intel), you can extract the files you need from the HP Printer Drivers 5.1 package from Apple to install the driver for the HP Laserjet 1018-1020-1022 without the need to run the installer. If the new drivers from Apple don't do it for you, you can try the following (which I have also posted on Apple's support forum to help others who are having the same issue):
