well, i got a new printer, hurrah. i hate printers.
printers are irritating. if they work, they work. if they
go wrong (drivers, hardware etc), it's a _complete_ pain in
the neck to fix.
my fun-and-games began when recompiling the kernel. the
_actual_ problem was that you have to mkdev a device number
of 180 in /dev, which i only discovered later by activating
(kernel compile) mounting (/dev/devfs) devfs and doing ls
-al /dev/devfs/bus/usb/lp0 AAAAGH.
2.4.4 usb support is crap, it failed to create the
2.4.7 created the device but i didn't know about device
number 180, so downloaded patches
2.4.10,11,12,13,14,15,16,17, 2.4.14-2.5.0 and 2.5.1.
compiled up multiple kernels, got on with the job of running
lost all my pcmcia options and i forgot about pcmcia
support _and_ i forgot about ppp async ARGH. rediscovered
discovered devfs - experimental device filesystem
in 2.5.1, hurrah! it showed me the device number! cat
'hello you stupid printer^L' > /dev/devfs/bus/usb/lp0
hurrah! it worked!
okay, *groan* so there was nothing wrong with 2.4.7,
12 _or_ 2.5.1. now to recapture my lost settings, including
my pcmcia 3c574/serial card...
anyway, the upshot is that i am now the proud owner of a
_working_ and cute and very small portable Canon BJC55
deskjet printer. it sings to me when you put the new
cartridge in [which is why it's cute - you think i'd call a
printer 'cute' otherwise??? :) ] as it tests it.
i have no idea how to print graphics on it, and lpd
recognise it properly, but i don't actually care. cat
file.txt > /dev/usblp0 is good enough for me!
i can now print out "stuff" like invoices and faxes and
statements for people, which i am ever so pleased about. of
course... everyone else i talk to takes this kind of thing
totally for granted [well _duur_ of _course_ you can print
stuff out these days, this _is_ the modern age you backwards
remember the story i told last year about the royal navy
1850 commissioning sea charts to be a) calculated accurately
b) _printed_ accurately, after the royal navy discovered
that 1 in 3 charts had copying (yes, copying) errors. an
error in the third decimal place on sea charts can result in
being off-course by hundreds of miles.
anyway: we seem to have the calculating bit down pat,
the printing is still leaving a lot to be desired... :)
