Printer Connection
Prepare Linux/IrDA as described above. Especially check for the existence of /dev/irlpt*
(if it doesn't exists do as root mknod /dev/irlpt0 c 161 16). Now you may perform a first and
simple test. Try to write a small file to /dev/irlpt0 by
cat FILE >/dev/irlpt0. Do not
wonder about a bad format (the lines form sort of steps) this is just a first check. If this
doesn't work please check the permissions of /dev/irlpt0. Watch whether the connection
indicator of your printer shows activity, e.g. the green light above the InfraRed port of a HP
6P/MP comes on (lower left hand corner, near the paper tray).
The cat command will not produce formatted output, but is useful for testing. If it works,
you may set up
an IrDA capable printer depending on your printer system. See the
documentation, e.g. the Printing-HOWTO from LinuxPrinting.org for detailed information.
With the
2100:
Common Unix Printing System - CUPS
use for example with a HP LaserJet
lpadmin -p IRDA_PRINTER_NAME -v parallel:/dev/irlpt0 -E -m de/hp2100_6.ppd.gz

may edit /etc/printcap and
include irlpt0 as the printer device.
The better way is to change your /etc/printcap to use /dev/irlpt0 in addition or instead of
/dev/lp1.
For easy printer setup you may use a printing software like APSFILTER, MagicFilter
EZ-Magic (with RedHat there should also be a GUI for this purpose). Make a copy of
/etc/printcap before.
Example for APSFILTER with a HP 6P (non-postscript, HP 6MP is with postscript). The
two relevant questions are: "Do you have a (s)serial or a (p)arallel printer interface?"
Answer "p"
"What's the device name for your parallel printer interface?"
Answer
"/dev/irlpt0"
Restart the print daemon with kill -HUP >PID of lpd>. If you use another print daemon
choose the according command.
LAN Connection - IrLAN
You might connect your Linux box using IrLAN to another network device such as a Linux
box with IrLAN, a HP NetBeamer or a Microsoft-Windows95 box with Infrared Network
Device support. But currently this protocol is no longer maintained by the Linux/IrDA core
team.
HP NetBeamer Connection
As far as I know this device uses IrLAN. But currently this protocol is no longer maintained
by the Linux/IrDA core team.
