We report on measurements of differential cross sections dσ/dpT for prompt charm meson production in pp̅ collisions at s=1.96   TeV using 5.8±0.3  pb-1 of data from the CDF II detector at the Fermilab Tevatron. The data are collected with a new trigger that is sensitive to the long lifetime of hadrons containing heavy flavor. The charm meson cross sections are measured in the central rapidity region |y|≤1 in four fully reconstructed decay modes: D0K-π+, D*+D0π+, D+K-π+π+, Ds+φπ+, and their charge conjugates. The measured cross sections are compared to theoretical calculations.
