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?
