You may find something at sunsite in the directory system/printing. I
have been looking there because I can't make work my Canon LBP-660 on
linux. And send me the canon's tech support email, please.

Hi ,
I am at the same point of decision ... I use a HP520 (b/w) printer which is still
printing with
acceptabel speed and good quality although it had to print many pages during 4
years.
Once I had to change the traktor as it was defect. But HP sold a 3-year
warrantity as
standard and so I were asked if I preferred to exchange the printer to
refurbished one
or if I wanted to wait for my printer to be repaired (6 weeks) and returned.
I decided to exchange the printer... and a forwarding agency came to my door two
days later... and the best: no costs at all!!
Epson only gives 1 year of warrantity and no exchange service.
Be aware, that Epson stylus printers even print slower. I would not belief that
first
but saw it (a chart / text combination) with my own eyes.
HP prints with _real_ 600x600 dots and manages (with the newest 895cxi @ some 380
EURO) with
it's retTechnology to place up to 12 dots at the same place.
Epson's calculation: 4 colors do 4 dots which make 1 mixed (blurred) resulting
point. So you have to devide
1440 through 4 ....
for my concern: I compared the Canon BJ7000 (with POP tech) (some 350 EURO) with
the HP 895 Cxi.
Concerning speed: HP manages to output up to 8 pages (b/w) per minute, Canon upto
5.
Color: complex corel draw's steam engine (1 page): HP about 7 minutes, Canon
about 12(!) minutes.
Big advantage of Canon: special ink (with POP) is waterproof! and you can print
on handmade paper
and cotton without any problems...
Canon's Color prints look more natural.
I will decide to buy the HP again as the HP finally uses less ink on every print
so that price per print
is in good relation.
Hope to have confused you a little more...
Carsten

None yet, There is still a long way to go on the USB project. Also from what I
gather they are having problems getting the specs from the manufacturers. also
for USB project info try http://www.nv.org/linux/uusbd-www/ instead of the
link you posted or Inaky's site

Its the same number of colors, the last 8 bits are generally ignored,
though they can be used to hold non-image information. 32 bit servers
are easier to write and can be faster because you can grab a
particular four byte pixel with a single machine instruction.

The problem is that there's no standard for video over USB. Every vendor
is doing it differently, so you have to get specs from the vendor, and
they're pretty tight-lipped about proprietary designs.
Check out http:/www.usb.org to see which device classes have a firm
standard and which ones are still in flux. You can also surf my
collection of USB links at http://www.well.com/user/shiva/tech.html#usb
to get lots of other USB info.

It sounds like this guy's looking for ways to make his filesystem
more robust and recoverable by any means, hook or crook, under linux,
and as inexpensively as possible.
If so, then I would suggest an alternative, higher-level approach
which would get you a more flexible/featureful solution and require
considerably less coding: make a cheap (ie, from mostly used parts)
linux CVS server, put it on the network with your "primary" system,
and write a script periodically run by cron which checks file changes
into the CVS repository.
This gives you the flexibility to describe which files need to be
restorable and which do not (ie, if you still have the install CD,
then you don't need to save your nonchanging executables and data
files into CVS), and the ability to restore any file or filesystem
heirarchy (ie, /* or /usr/* or /home/yourname/prog/projectfoo/*) to
any previous state. An "undelete" or "regress" script would simply
call the cvs client with appropriate arguments. If your hard drive
crashes entirely, you can "check out" the most recent revision of
your filesystem onto a new hard disk.
I've been considering doing this myself since a couple weeks ago,
when in a too-sleepy state I deleted the only copy of about 24 solid
hours' worth of code. I still get so depressed thinking about it
that I've put off going back and re-writing it all, though it's a
thing I need to do sometime. I do back up my media occasionally,
but when I'm working hard on a project and the bit's in my teeth it
is very difficult to remember to do it.
The most expensive part of the CVS server would be the hard disk,
which you want to be reliable and large. Here's what I can get at
local used computer stores (San Jose / Santa Clara / Sunnyvale
areas in South Bay, specifically Sharon Industries and Weird Stuff
Warehouse; some of these are approximations, but I'll try to appro-
ximate high):
386DX33 + motherboard $ 10 used
16MB RAM $ 20 used
Case with power supply $ 15 used
ISA 512K SVGA card $ 5 used
IDE/FD/S/P IO card $ 10 used
NE2K 10bC ethernet card $ 15 <-- NEW
10.1GB IBM DeskStar $193 <-- NEW
Total: $268, plus tax on the ethernet and hard disk. Note that 72%
of that cost is the storage media itself. The only caveat is that
you need to get a 386 motherboard with a sufficiently recent BIOS
that you can describe a "custom" (ie, ID = USER) disk in its setup.
No monitor or keyboard is necessary once you have it all set up
correctly and running linux. You can use your other computer's
keyboard, monitor, and cdrom to get linux installed, but after
that it can sit headless on the network and be accessed exclusively
remotely (ie, telnet/rlogin/ftp/rsh/cvs, etc), left in the corner
to chuckle to itself, ignored, while it backs up your files.
All of these components tend to be very very robust. I use
old 386DX33 and 386SX40 motherboards/CPUs for various projects,
and they're forever reliable. Even if something does break down,
only the hard disk is critical for maintaining data integrity,
and the low-RPM version of the IBM DeskStar is very robust. If
you are very concerned, well, throw a second hard disk onto the
IDE bus (which is slow, but speed is fairly irrelevant since the
updates are batched and CVS handles updates fairly intelligently)
and put a CVS repository on that too, and submit file changes to
both repositories. Or to make it more robust, keep each CVS's
disk on a different computer (for an additional cost of $75 for
the cpu, motherboard, etc).
Of course you could eschew with the cheap computer + network
entirely and just put the CVS repository on a disk on your own
computer's disk bus, and save yourself the $75 and the work of
collecting parts and installing linux on a new box. That just
occured to me. The only reason I'm doing it that way here at
home is because I already have most of the parts, I already have
the network, I've installed linux so many times that it's a no-
brainer, and I have multiple computer systems on the network
that I'd like to have backed up this way. Also, (warning -- the
rest of this post is mostly blather about my network setup at home
and some comments about administration ideology, so if you don't
care you can quit reading now) I've found it very useful to break
up my system functions onto as many independent systems as possible.
The main server really needs to be up 24/7; I sometimes need to pull
things from it at work, and it services web pages and email, and
since it's a pseudo-open system there are various other geeks who
use it remotely at random times. So I leave it where it is and I
don't touch it. The network pipe to my ISP is mounted on another
system, which I can spuriously reboot or power down / upgrade hard-
ware / power back up without interfering with the main server's
operations. The system downstairs is the only one running a GUI.
It's just a user interface to the server most of the time, but when
something goes wrong with the network it's nice to be able to use it
to check things out. And of course running a GUI makes it much less
robust (and makes me less robust too -- when I'm called on to make
configuration changes to make it look/feel better, sometimes I'll
accidently overwrite a critical file or two -- oops!), but since
it's a completely noncritical system it doesn't matter. Rebooting
it by no means interferes with net connectivity or web serving, etc.
Sheerly for robustness' sake I avoid using NFS to provide a system
with files important to its operation. I like to keep each system
maximally functional independent of any other system. At work, each
user is massively dependent on NFS-mounted directories, and I under-
stand why it's nice to do things this way. It frees up local disk
space, makes system administration incredibly easier, and guarantees
that each system will have similar environments. On the other hand,
it also means that when one of the NFS servers goes down, everyone in
the company (or at least in the engineering department) goes home.
Everyone except me -- a few months after starting work there, I
brought a spare 486 to work and put it on the network, but kept it
independent of the NFS servers and did my own administration on it.
Often I would continue working using it while everyone else's systems
were frozen up tight, blocked on attempts to run executables from NFS
directories which were no longer there. As long as my home network
remains a fairly reasonable size, I will refrain from making it quite
so fragile. (And I will write auto-administration scripts to maintain
common environments via rsh/rcp before I start using NFS.)

I have the Color QuickCam VC that I would dearly love the specs for.
I have the USB specs for OHCI, UHCI, CCI, audio, etc from
www.usb.org. I am on the linux-usb mailing list. The specs just
haven't been made available yet.
Please ask logitech to provide specs. Everyone. But be polite!
There are engineers at Logitech who would like to support Linux.
There is just a question of politics that needs to be worked around.
If Logitech perceives a demand for their products in the Linux
community, then the USB spec for their cameras should become available
with a driver following a short while after that.

With RedHat 5.2, you will have to go into fdisk 'expert' mode and
change the number of cylinders to the correct LBA value. You'll
have to determine the exact number for your drive, but it will be
somewhere around 1400-1500. Does DOS fdisk tell you this
number?
Note: Realize that installing Linux entirely above the 1024 cylinder
boundary means you will have to boot from floppy disk or using
loadlin - you won't be able to boot from the hard drive using lilo
in the master boot record.

yes... recompile the kernel folowing the advice in the sound HOWTO and
the documentation about AWE32 that comes with it. I was able to compile

yes... that is what happens when you have either the "PnP aware OS"
option enabled in the BIOS or do a warm boot from a PnP OS
One option that I saw documented (I forgot where) said that if you have
an ATX powersupply, shuting it down is not enough... you have to unpulg
the box (the cmos draws minimal power otherwise, saving the PnP
settings) to get it to work.
A much better solution that worked for me is to upgrade to kernel 2.2.1,
enable PnP in the kernel config (I also installed isapnp... dunno if
that was part of the solution, but it's worth a try). IMO... this is
your only option if you boot windoze and linux on the same box.
