Recent versions of MacOS heavily favour AirPrint as the driver. These can lack extra options, such as resolution.

When printing, the Print Dialog will typically show "Normal" as the only option. This can be found under the "Media & Quality" section of the Print Dialog.

If you know your printer has a higher resolution, follow these steps to add it:

1. Obtain the actual resolution from the manual. Mine says "HQ1200" which is actually 2400x600dpi.
2. Run lpstat -a to get a list of printers.
3. Run lpoptions -d printername -l to show the options. Mine has just a single resolution:
