While printing labels through DYMO Label Software (DLS) received an error message

Hi,
While printing labels through DYMO Label Software (DLS) I received an error message. It is indicating that label size not supported by my printer. My machine is running with Windows Vista. If you have any idea for the error message, please help.
Thanks in advance.

Error
This label is not supported by your printer. Either selected label is too wide for the printer or the printer driver is out of date. To download the latest driver, go to the support section at www.dymo.com.
