Now i'm setting up a new system on a different pc (it will be a lan server with cups), donwloaded your new drivers, followed your instruction about building.
Now when i send locally a print-test-page request then my clp-2160's green led start blinking, lcd tells "Printing..." but nothing else happen. After a few seconds cups don't show the job anymore.
Did new code break compatibility?

I can't stop this job from the printer itself, i'm forced to shutdown printer and open it again :(

Edit: forgot to mention, i run latest Kubuntu Linux.]]> fede Samsung CLX-2160 Thu, 29 Jul 2010 10:13:58 -0400 http://foo2zjs.rkkda.com/forum/read.php?38,1817,1817#msg-1817 http://foo2zjs.rkkda.com/forum/read.php?38,1817,1817#msg-1817
I've just spent a while trying to get decent quality colour printing from my Ubuntu 8.10 desktop machine on my CLX-2160N, but to no avail :-(

Whatever ICM profile or image quality I select, colours always print too dark (compared to the screen and/or the Windows driver which is well matched).

I also find that printing digital photos (3k5 x 2k3 pixels) using GIMP or eye-of-gnome (eog) takes a very long time while ghostscript renders (several minutes @ 600x600 DPI), after a while the 'socket' backend also consumes all the remaining CPU until finally the printer starts up.. this doesn't seem right.

Ubuntu currently use Ghostscript 8.63-0ubuntu6.2, which claims to be 8.63 when asked, could this be the problem (I have seen mention that 8.63 can have colour issues)?

As an experiment I tried printing to a PostScript file, then using foo2qpdl -c to convert to QPDL, and finally qpdldecode to extract image data, hoping to be able to see the colour issues in the resulting .pbm files, but alas these appear to be broken half-way through as well as being separate CMYK planes (I could reassemble in GIMP I suppose..)

FWIW the syslog entries from a typical print activity look like this:

Thanks for any answers,
Phil.]]> Phlash Samsung CLX-2160 Mon, 15 Feb 2010 16:10:23 -0500 http://foo2zjs.rkkda.com/forum/read.php?38,1794,1794#msg-1794 http://foo2zjs.rkkda.com/forum/read.php?38,1794,1794#msg-1794 Posted by: Stuart Reid (IP Logged)

Use the script at www.jon.demon.co.uk/dell1600n-net-scan/

I have this running all the time on my home server. I configured it like this:

Open the crontab like so:
crontab -e

Enter the following (modify it for your needs):
@reboot /usr/sbin/dell-1600n-net-scan.pl --listen 192.168.1.20 --clx2160n --multi-session --scan-dir /files/scans

Press ctrl+x, then y

That's it! It will run persistently in the background and always be ready. Any network scans will automagically appear in the designated folder.]]> rickrich Samsung CLX-2160 Sat, 21 Feb 2009 15:10:26 -0500 http://foo2zjs.rkkda.com/forum/read.php?38,1100,1100#msg-1100 http://foo2zjs.rkkda.com/forum/read.php?38,1100,1100#msg-1100
It's obvious that their Linux driver team don't actually bother testing the driver on the printer. Or they perceive Linux users as easy prey for more frequent toner refills.

Issue 1 ; colour > black conversion quality

Mono prints appear to be about equivalent in terms of toner weight, but the foo2qpdl driver in Mono mode doesn't quite have the same quality as the Samsung driver set to Grayscale. The issue here seems to be coloured lines and text that have been converted to black ; the foo2qpdl driver produces a very slight jagged edge, even on straight lines. The Samsung driver does not. Is this a halftone issue as described on the front page? I wasn't able to work out how to switch to the alternate colour correction method, so I'm stuck using the ICM file at present. This is not especially noticeable, but all feedback is good feedback.

Issue 2 ; yellow separation is off by about a mm.

The Samsung driver, despite it's extreme over-use of toner, gets the placement of the Y colour separation right (or closer than foo2qpdl). foo2qpdl appears to place the Y separation approximately 1mm too high on my hardware. Thin lines with a yellow component are especially noticeable. There is also a "halo" effect on any text with a yellow component. The displacement is about 1mm too high ; the horizontal looks right (orange and green dotted and dashed lines on a square edged graph are best to demonstrate this). Is there a way to adjust this?]]> awilkins Samsung CLX-2160 Wed, 02 Apr 2008 16:44:41 -0400
