The printer is DYMO LabelWriter SE 300. I use it as a POS receipt printer from 
SQL-LEDGER.
When I was setting up the printer for the first time I was running SUSE 9.0.
I configured it on a raw que in CUPS and it worked without a problem until 
upgrade to SUSE 10.2. (This was not the first upgrade I have done. I went 
through every version)

CUPS setup was simple. 
These are the settings that have been working for a couple of years:
Description: Receipt Printer
Location: shop
Make and Model: Local Raw Printer
Printer State: stopped, accepting jobs, published.
Device URI: serial:/dev/ttyS0?baud=9600+bits=8+parity=none+flow=soft

When it stopped for the first time I tried:
Changing permitions on dev/ttyS0 - that did not make any difference. 
I tried to delete the printer using yast and reinstall it - no use
The only way how to make it working again is to delete the printer using CUPS 
and then set it up with Yast.
When I upgrade something significant (kernel for example) I usually restart 
the computer. The printer then stops working and I have to do the whole thing 
again. It did however stop once without any reason. As if access permitions 
for ttyS0 were changed by the system.
