[9fans] JetDirect printing

[Lucio De Re]

Within /sys/lib/lp/devices, the following entries:

# 2c307			2C-307	alice			tcp!mh2c307!9100	81920	post+600dpi			generic		generic		generic		generic		tcppost		FIFO
# fn			2C-501	helix			tcp!fn!9100			81920	post2+600dpi+duplex	generic		generic		generic		generic		tcppost		FIFO

are intended for use with JetDirect connected printers.  But how do
"alice" and "helix" actually deal with this?

I resorted to

hpps		-		sparkle		hpis2	81920	post2+1200dpi+duplex generic	lpdspool		lpd		- 	-		FIFO		-		-

for my purposes, but it falls short of the intended use.  Is there a
direct way to talk to such printers?

The other significant bit is:

# See /sys/lib/postscript/prologues/hpsimx.ps for a fix to make it default

regarding duplex operation.  The entry being referred to here is
missing, the similarly named /sys/lib/postscript/prologues/hp4simx.ps
does not seem to provide the promised goods.  Is the missing
information available elsewhere?

They deal with it by invoking the tcppost transport.
See /sys/lib/lp/daemon/tcppost.
