I got me after studying available linux printer drivers for label printers a used Zebra ZPL 3844-Z with build in printserver.
The drivers page says Zebra drivers are included with cups.
Download File: End User License Agreement
With Ubuntu 11.04 it works as it should, enter socket://IP.ADR.ES.S:9100 select Zebra and ZPL an ready to print with glabels.
When I open YAST printer setup there is ZEBRA found but not drivers.
Unter CUPS there isn’t even an entry for Zebra.
What happened to the Zebra drivers?
Is there someone that could point me to?
I note that Zebra have Linux driver available for recent models, but not for leagcy models (such as yours). Googling around, I found that some Zebra drivers are available from here:
SourceForge.net: Zebra Technologies CUPS printer drivers - Project Web Hosting - Open Source Software
You may end up having to edit one of the ppd files to suit the specifics of your model, or perhaps it will be sufficiently close to work with your label printer.
In an effort to assist you further, I downloaded the zebraCupsDrivers.zip file, unzipped the file and copied just the zebra.ppd file to my /usr/share/cups/model/ directory. (You’ll need root privileges to do this). This should be all you require to configure with.
Although I don’t own a Zebra printer, I started the CUPS web config tool (I prefer this utility over YaST) via
http://localhost:631/admi
Selected ‘Add Printer’ and pretended to configure a remote printer (a good method I use to assist others when configuring printers or particular drivers). The Zebra driver was now in my list of available printer models to choose from. That’s as far as I can go without having the hardware to play with. 
I hope this helps.
Strange, I did search for zebra cups driver. Yesterday I would not find it, today the sourceforge link is the number one.
I just used the upload function in CUPS to copy the ppd.
No it just works.
Thank you for your time and help.
Anyway, why aren’t they shipped with opensuse, as ubuntu does?
Glad to be of assistance.

Are you sure about that? This Ubuntu thread suggests otherwise. I’m guessing that its more to do with the CUPS version shipped with a particular distro version. You’d need to ask this question to the CUPS people. Maybe now that Apple Inc are the developers behind CUPS, there are potential legal issues involved.
If you search
Drivers - CUPS
you’ll see that this driver is no longer available from a CUPS perspective.

That is a question for the developers, not this forum. The usual reason is that
the license is wrong. In openSUSE, only software licensed under the GPL is
allowed. As the zebra cups driver is (implicitly) licensed under the GPL and the
LGPL, it should be OK. The only problem is that the zip file does not contain a
LICENSE file. Without that, the openSUSE maintainers might have decided that the
license is inappropriate and did not include the software.
Just installed the zebra printer on some elder notebooks that cannot be upgraded due to the i855m Problem.
Interestingly OpenSUSE 11.2 came with the zebra drivers.
