We review the phenomenology of $\pi^{0}$ production at large transverse momentum in proton-induced collisions. Uncertainties in the next-to-leading-order predictions of Quantum Chromodynamics are discussed. The comparison with data reveals that the disagreement between theory and experiment lies essentially in an overall normalization factor. The situation for $\pi^{0}$ production is contrasted with that of prompt-photon production in hadronic collisions.
