The modification of silver screen‐printed electrodes with a dodecyl benzenesulfonic acid and KCl solution was performed by inkjet printing. Scanning Electron Microscopy was performed to characterize the electrode surfaces. Electrochemical reduction of H 2 O 2 was studied and compared to electrodes modified by dip‐coating. Analytical parameters of the all‐printed electrode such as LOD, sensitivity and inter‐electrode reproducibility were calculated (5.8×10 −6 M, 4.9×10 −2 AM −1 cm −2 and approx. 10 %) and contrasted with other data in the literature for the measurement of H 2 O 2 . Ink jet printing led to reductions in required surface modification times and improved signal to background levels and reproducibility.
