In this article we continue from \cite{ sub2-1} the study of normal analytic compactifications of $\cc^2$ from the point of view of their associated pencils of jets of curve germs centered at infinity. If $\bar X$ is a normal analytic compactification of $\cc^2$ which is { \em primitive}, i.e.\ $\bar X \setminus \cc^2$ is irreducible curve, then we show that $\bar X$ is projective iff $\bar X$ is algebraic iff at least one of the jets in the associated pencil of jets of curve-germs can be represented by a planar curve with one place at infinity. As a result we show that there are primitive normal analytic compactifications of $\cc^2$ which are { \em not} algebraic. We give explicit criteria for determining if the primitive compactification corresponding to a jet of curve germs at infinity is projective or not.
