From the LS2208 Product Reference Guide you should print and scan the following barcodes:
Begin New Rule Adobe page 232 of 342
Send all data that remains Adobe page 246 of 342
Send tab key Adobe page 286 of 342
Send 1 Adobe page 270 of 342
Save Rule Adobe page 232 of 342

That should do it. If you find the scanner sends the 1 too quickly after the tab key you may want to scan Send Pause in between the Send tab key and Send 1 statements.

Thanks a lot
