	especially on recent RedHat systems that use the “printconf”
	database of queues.
	When using printconf, the /etc/printcap file is automatically
	refreshed from the database of printers managed by the
	system (usually through the “printtool” command), and the
	queues in /etc/printcap.local are appended to the resulting
	file. Since the default queue in LPRng is defined as the first
	queue in /etc/printcap, it is not possible for the Linux Printer
	Package to change the default when some queues have
	otherwise been defined using printtool.
	LPD systems identify the default queue as the one named “lp”.
	Thus, if there is already a queue by this name, and if it
	doesn’t have any alias, you won’t be able to change the
	default. To work around this, you can either delete the queue
	or rename it by manually editing the /etc/printcap file.
