      Have you checked so there's not processes hogging the cpu? I followed
      Martin Michlamayr's instructions here
      http://www.cyrius.com/debian/nslu2/ and remember I had problem with one
      program. (Sorry, don't remember the name of it but it's an apt
      database-something that I thinks starts with an X in it's name.) After I
      removed that it runs a lot better.

        You can use "top" to check on the processes running. You can also use "free" to check your memory status. In my office, I've been using one of my NSLU2 with SlugOS as a print/scan-server for my HP Scanner/Printer for some time now and been running pretty well. The Epson shouldn't be more of a challenge.

          The first time I ran cups it hogged everything, it took 10 mins to log with SSH, and cupsd was
          hogging 85% of the cpu, after that its been about 15%, Looking at the led on the flash stick its
          flashing away all the time cupds is in processing with just one job in the queue.
          When I untarred the debian package from the laptop to the flash stick it took 15 ~20 mins.
          and it took 30 mins for cups and its dependences to install . 30M broadband here.
          I'll look through some more documentation and surplus package that can be slowing it down.
          I'm a bit miffed that the flash sticks I thought were good were duff. If it had been just one that
          fdisk and gparted didn't like , I may have rumbled earlier it was a flash problem.
          There's a job in the queue at the moment , cupds isnit taking more than 10% cpu and 10% mem,
          but pdftopdf was taking 35% of each ,
          Free showed 1105 of swap used
          the job waiting is just the testpage, so why pdftopdf runs I dont know.

            Well its now printing albeit very slowly,, but withing 5 mins of putting a test page in the queue.
            I found a slightly faster flash, and loaded several times, before , I only partition 4 GB of the 8
            GB stick, then it booted OK.
            Running top while printing shows usage up to 85% but memory only 50%. I hoping the faster flash
            stick will speed things up, as it is swapping during the process. I hope replacing it with a
            pogoplug later next week will speed things up enough. Its not cups that hogs the processor its the
            page rendering.

              Sounds like you actually used the cups printer driver and doing most of the processing on the NSLU2. What I did instead and mind you, I used SlugOS, is to use the instructions on http://www.nslu2-linux.org/wiki/HowTo/AddPrinter . It references the pass through hp990c driver. I load the actual driver on the local machine so most of the processing happens there before it goes to the remote NSLU2 cups server. You could also setup the p910nd daemon, instead, but it does not allow for spooling while the other way does.

                Interesting, that you load the driver on the local machine before passing it to the remote cups
                server. How did you do that ?. the remote cups server, NSLU2, will broadcast the HP990c. , so how
                do you get the local cups client to handle the Epson R285 data.
                I did look at the wiki page and tried with slugos, but I could not get the cups control page with
                elinks, both local on the NSLU2 and remotely I got page 404. Thats why in the end I went with
                Debian.

                  You probably couldn't get to the cups:631 page because you didn't set up the proper authorizations in "/opt/etc/cups/cupsd.conf" ("Allow From 127.0.0.1" and if you want from your desktop "Allow From 192.168.X.0/24", change this to your proper subnet, check "man cupsd.conf"). You should also check to make sure cups is actually working with ps. If it is, then it is an authorization problem. Maurice set up an Epson using the info on "http://www.nslu2-linux.org/wiki/HowTo/AddPrinter". You probably need to make sure that the mime files in "/opt/etc/cups" have the raw options uncommented (might be raw files in your Debian version). You can Google "cups pass through" and "cups local raw printer" for more info. Use the internet printing protocol on your local machine. You could do the same thing in Debian (or any other Linux), just depends on variations in CUPS version.

                    Many thanks for that , As soon as the new flash drives arrive, I guess Monday, I'll clone the
                    current image, and try that again.
                    I have a major problem with my Philips TU pro webcam, its semi died , the images are low res, over
                    exposed , it could be used for movement detection , but you'd never tell what moved :(
                    I'm beginning how difficult at times it is to run a machine headless

                    Any suggestions for a low cost web cam that will give a reasonable definition/quality picture. Its
                    only going to be used to capture intruder images, hopefully none. Or maybe what the cat does when
                    we go out, something I might find on ebay $20 or less.

                    Thanks for the help

                      Any Linux supported one should work, just Google "Linux usb webcam". You might need a powered hub since some can really draw some current. You can check with "cat /proc/bus/usb/devices" if you have usbfs mounted on /proc/bus/usb or "usb-devices" on newer systems. I had an stv680 camera that would draw quite a bit of power.
                      Like I said previously, an IP cam like a Foscam clone works pretty well and can also feed a small arm server running "motion" like bturrie mentioned or be standalone. I actually use an easycap 002 cctv capture dongle for 4 feeds. I think several companies already makes a compact 4 channel ip cctv server like http://www.ambery.com/4webvisewitv.html.
                      The Ubuntu guys have a webpage https://help.ubuntu.com/community/Webcam that has a link to a list of recommended webcams and there is an older list at http://www.tldp.org/HOWTO/html_single/Webcam-HOWTO/ . I have an older ibmcam and can tell you the picture is not very good so I wouldn't buy that.
