TROY SECURITY - original - toner cartridge (alternative for: HP CF280A)

TROY Security Toner allows you to print as usual, but alerts you if your documents have been tampered with. When chemical alteration is attempted, the patented security agent forces a bright red stain to permeate through the document, protecting the printed words and graphics. TROY Security Toner adds a cost-effective layer of security to standard applications such as educational transcripts, medical records, legal documents, and more.
