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:

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

	#!/bin/bash

	time="1" # one second
	int="eth1" # network interface

	while true
	do
	txbytes_old="`cat /sys/class/net/$int/statistics/tx_bytes`" # sent bytes
	rxbytes_old="`cat /sys/class/net/$int/statistics/rx_bytes`" # recv bytes
	sleep $time

	# Calculates Growing Degree Days (GDD) using generally-accepted methods
	# defined by the Division of Agriculture and Natural Resources, University
	# of California [1].
	#
	# The single-sine method seems to be the defacto way of determining a GDD [2].
	#
	# The triangulation methods are originally from [3] and are used to correct
	# a transcription error in [1].
