Pitney Bowes Ink & Labels
Be wary of some cheap compatible cartridges as we have first hand experience of some possibly causing damage or premature wearing to some franking machine print heads which is why you will only find GENUINE ORIGINAL Pitney Bowes cartridges on this site.
Important note regarding Royal Mail approved compatible cartridges: These have only been approved for their readability by the Royal Mail and compatibility criteria for recognition by IMP / ILSM sorting machines. The Royal Mail point out that this evidences only that the ink in these cartridges have been tested against and meets Royal Mail’s criteria and not its suitability for use with franking machines.
The simple answer is, stick to genuine lower priced originals from us!
