# Installs a new atalk printer into the printcap etc in a manner
# compatible with Linux printtool.  It assumes that printtool etc.
# are installed.  Netatalk must be working, as must nbplkup and pap.
#
# Arguments are:
# 1. queue name (may be "name1|name2")
# 2. full ethertalk path (MUST be in quotes)
#
# There is some error checking
