Number (3) appears to be the culprit.

First off, my apologies for the long delay in posting this summary. I haven't
yet completely solved the problem, but I am making progress. It seems the
problem lies with the fact that our TeX software requires a number of fonts
and operators be downloaded to the printer from the host. Birger A. Wathne
was on the right track when he suggested playing with the sizes of the
internal buffers. By playing with the memory for downloaded fonts and the
PSHeap I can inconsistently print jobs that never would print before. Still
not perfect, but at least it's progress. Once I have things well in hand I'll
post a more complete summary.

Several people suggested that I check to ensure that the header page was being
suppressed (":sh:" in the printcap entry). I had already done this.

My thanks to all who responded:
