Abstract: The next-to-leading open charm production in $\gamma p$ collisions is calculated within the Perturbative Fragmentation Functions formalism, to allow resummation of $\as\log(\pt^2/m^2)$ terms. In the large $\pt$ region $(\pt > m)$ the result is consistent with the fixed order NLO calculation, small discrepancies being found for very large $\pt$ and at the edge of phase space. The two approaches differ in the definition and the relative contribution of the direct and resolved terms, but essentially agree on their sum. The resummation is found to lead to a reduced sensitivity to the choice of the renormalization/factorization scale.
