  brilliant - absolutely brilliant. Thank you. Thought I would have to trash my printer and the unused ink cartridges. Only hiccup was needing to disable my security protection to install this wonderful product. Used it as a trial - which proved it worked - then bought the key to finish the job. I am wrapped as you have saved me hundreds of dollars as there is nothing wrong with the quality of the printing. Cheers, Alan.

  I spent 4 hours trying to get my r340 to work then l I used your program to reset the protection counter. I have just printed 5 pages and 4 disks. Slightly cryptic instructions but it worked perfectly. it took me all of 5 minutes.
