The BJC-80 is a portable colour bubblejet printer with quite good resolution (720dpi horizontal, 360dpi vertical). It is similar in performance to some of the desktop printers like the BJC-210SP, but is very compact and suited to carrying with with a laptop. It has an IrDA interface which works with Linux IrDA (in addition to an ordinary parallel interface). There are no switches to select the interface to be used. I had access to a BJC-50 for a short period and I believe it will work with Linux IrDA in an identical manner.
In my experience the printer will work happily on a 12V DC power source, such as the one on my yacht Windclimber.
The printer is supposed to be able to work as a
scanner as well, but
there does not seem to be any information available on how to drive it with
Kernel Version Dependencies
I have not found the BJC-80 to work with all kernel versions. If you are
starting afresh I would recommend going to kernel 2.2.13 which works
with some subsequent versions was been mixed. The linux irda major device
number has changed with kernel versions. To determine the correct
number to insert in /etc/conf.modules, execute:
grep MAJOR /usr/src/linux/include/net/irda/*
and use the number disclosed there, almost certainly 161 unless you are trying
a very old kernel (when it was 60).
The BJC-80 seems to be a bit slow in the discovery phase, and as of
linux-2.2.7 and up to linux-2.2.pre15
will not be discovered unless the timeout is increased.
I do this in my IrDA startup script which is version dependent:
# irda start script for linux 2.2.13 and later and
# irda-utils-0.9.5 and later
/sbin/irattach /dev/ttyS0 -s 1
echo 110 > /proc/sys/net/irda/slot_timeout
echo start bj80 | lpc
for earlier versions:
# irda start script for linux 2.2.7 and irda-utils-0.9.4
echo 110 > /proc/sys/net/irda/slot_timeout
irmanager -d 1
The BJC-80 appears to be the same as a BJC-600 as far the input requirements
are concerned. A script like:
# Print Postscript to the Canon BJC-80 Bubble Jet Printer
# seems to behave the same as a BJC-600
gs -sPAPERSIZE=a4 -sDEVICE=bjc600 -sOUTPUTFILE=- -q -dNOPAUSE - quit.ps
can be used in a pipeline from PostScript to the printer, e.g. invoked by
lpd. In my case, the script is kept in /usr/local/lib/lpd/ps2bj80
To use the BJC-80 successfully with lpd, lpd must be able to set the serial
line to raw mode (i.e.clear the
sgtty l_flags), and for best results, set the line speed
to 115,200 baud. There are two slightly different ways to achieve
this depending on the version of lpd you use.
This package, available by
is the basis of the lpr in some commercial distributions of Linux (e.g.
Red Hat, SUSE).
A version of the lpd set that supports these flags can be obtained at ftp://phoenix.physiol.usyd.edu.au/pub/lpd-5.9+l_flags.tar.gz
