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: [EMAIL PROTECTED] -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
