I have a serial receipt printer connected to my server. Printing System is CUPS on SuSe 10.2. Until upgrade it was working OK. Since then how ever I often get this message:

from CUPS. I have to play with it a little set up the printer again
"play with it a little" means doing what, precisely?
Which commands and with what arguments, exactly?
and it works for a while.
Until you do what???
Then it stops working again. How do I make it working permanently?
You haven't even told us how you got it working temporarily.
We are not mindreaders, so how in the world should we know?

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. -- Regards, George Osvald OK Studio ® http://www.okstudio.com.au Email: mail@okstudio.com.au -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
