Help! http://forums.justlinux.com/showthread.php?154463-CUPS-Label-Printer-Problem-Pause-after-each-job!-Help!&goto=newpost Tue, 18 Jun 2013 17:13:14 GMT Hello.

I need a help with my new debian wheezy server. I'm a linux user for +8years and already spend hours trying to solve this and couldn't so if anyone has a clue.. someone can please help?

The problem:
I replaced my old server running debian-6.0 with a new one running debian-7.0. I have a DYMO LabelWriter 450 USB Printer on it to print labels.

The labels are printed by a postscript using the lpr command:
lpr -#$qtd -r -P DYMO_LabelWriter_450 /path/to/my/postscript.ps

If i send more than one label to the printer, this command will run multiple times changing only the postscript file path (different label, different ps).

The problem is: the printer pauses seconds between each job/label... and this behavior wasn't like that before - before the printer prints one after another without pauses.

I already tried a lot of things and nothing worked.

One thing i noticed is i got this message for each job i send:
Jun 18 11:26:55 kernel: [ 723.602744] usblp0: USB Bidirectional printer dev 2 if 1 alt 0 proto 2 vid 0x04E8 pid 0x3433

i already tried to copy my old /etc/cups folder into my new server.
i tried to remove usblp module and blacklist it..
i tried to reinstall the printer in cups..
i tried cups 1.6.2 insted of 1.5 too
and tried more things.. without sucess

The problem is.. the printer is pausing between jobs.. how do i remove that? any ideas!?

I'm getting crazy about this ! ]]> Hardware cpl_ http://forums.justlinux.com/showthread.php?154463-CUPS-Label-Printer-Problem-Pause-after-each-job!-Help! Debian - sound and network not working after update http://forums.justlinux.com/showthread.php?154455-Debian-sound-and-network-not-working-after-update&goto=newpost Sat, 08 Jun 2013 17:27:57 GMT Hi All, hope someone can help with this. I've run a few updates since the upgrade to Wheezy without a problem but a series of updates last week seem to have thrown things out of kilter.

On restarting the system I was unable to get the keyboard and mouse to respond (both USB). Got around that by unplugging then reconnecting. When I logged in there was no sound output and no network connection (onboard sound and ethernet).

The sound hardware was showing as a dummy device under Sound Preferences. I ran alsa reload and the sound card reappeared. Manually selecting it under Hardware in Sound Preferences got it working. Rebooted and the same thing happened, and the mouse and keyboard again failed to work until unplugged and reconnected.

The network is not working at all. The /etc/network/interfaces file had apparently been changed with the manual information I'd put in being overwritten. I've changed it back, but it's not made any difference. Clicking on Network Manager (using Gnome by the way, in classic and Gnome 3 forms) shows no network device available. Checked the cable, and the ethernet light on the router is on.

For information here's the /etc/network/interfaces file, and the output of lspci and lsmod: -

The Linux PC is networked to a WinXP PC via a router exactly as it was (successfully) before the new install.

The Linux machine can read everything I want Ok from the XP machine, but the XP machine cannot now read from the Linux machine. All it sees is a short list of linux folder names which remain inert.

I have replaced the new config.lst with the previous one which worked just fine, so I doubt the problem is there.

I guess something else need setting on the Linux machine, but I need help here. ]]> Networking Toastrack http://forums.justlinux.com/showthread.php?154453-WInXP-cannot-access-mepis11-files-and-folders Do not use Ubuntu !!! http://forums.justlinux.com/showthread.php?154451-Do-not-use-Ubuntu-!!!&goto=newpost Thu, 30 May 2013 03:23:42 GMT For the following reasons don't install or recommend Ubuntu.

1. Development of Ubuntu is led by Canonical, Ltd. a UK-based "trading" company which generates revenue through the sale of "technical support" and "services."

2. By installing users agree to allow Ubuntu's parent company Canonical to collect user search data and IP addresses and to disclose this information to third parties including Facebook, Twitter, BBC and Amazon.

3. The adwares and spywares introduced in Ubuntu violates user's privacy and is one of the rare occasions in which a free software developer persists in keeping a malicious feature in its version of a program.

4. Whenever user searches the local files for a string using Ubuntu desktop, Ubuntu sends that string to one of Canonical's servers.

5. Ubuntu has received widespread objection from the open source community for violating free system distribution guidelines.

6. Canonical disgruntled upstream open source developers by introducing Mir, their own display server not derived from X11 or Wayland.

7. Ubuntu's policy prohibits commercial redistribution of exact copies of Ubuntu, denying the baseline freedom.

8. Ubuntu is basically Debian with extra "cool" look and is not binary compatible with Red Hat Enterprise Linux and CentOS which are used for most scientific development.

This is my first posting, and although I have dabbled with Linux, I think I am still somewhat of a beginner.

I have a widescreen monitor, with a native resolution of 1440 x 900. The graphics card is a Radeon 9000 series and the PC is showing it's age! I have tried various versions of Puppy, and all of them allow a setting of 1440 x 900 (albeit in the extended display choice) and the display is perfect. Other distros, however, don't have that choice, and so the display is distorted. I have tried looking for drivers on AMD's website but with no success. Why can Puppy do it and not others? My latest distro is Trisquel which works fine apart from the display distortion, and all of the others I have tried give the same problem.
Any help much appreciated. ]]> Hardware gozo97 http://forums.justlinux.com/showthread.php?154447-Display-resolution bash regex http://forums.justlinux.com/showthread.php?154443-bash-regex&goto=newpost Tue, 21 May 2013 22:16:03 GMT I am trying to make sure that the number entered for the barcode variable is exactly 10 digits long but it doesnt work and get the following error.

If I change the =~ to == I don't get an error but it still fails when it shouldnt, I assume thats because I am then comparing 2 different numbers for equality, rather than testing for an acceptable pattern.

I did get the following to work but it wasn't what I was going for.. also it allows numbers longer than 10 digits to be accepted.
