	LPRng, 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,
	therefore it is not possible for the Samsung 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, then 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.
