We present measurements of the ep{yields}ep{pi}{sup 0} cross section extracted at two values of four-momentum transfer Q{sup 2}=1.9 GeV{sup 2} and Q{sup 2}=2.3 GeV{sup 2} at Jefferson Lab Hall A. The kinematic range allows one to study the evolution of the extracted cross section as a function of Q{sup 2} and W. Results are confronted with Regge-inspired calculations and GPD predictions. An intepretation of our data within the framework of semi-inclusive deep inelastic scattering is also discussed.
