We just cut off the %EOF and concatenate them.

Which printer-specific commands do you mean?
Input tray selection in the ps file occurs as follows (for each document):
%%BeginFeature: *InputSlot Optional

  currentpagedevice /InputAttributes get 5 get
  dup null eq
  { pop }
  { dup length 1 add dict copy
    dup /InputAttributes
    1 dict dup /Priority [5] put
    put setpagedevice
  } ifelse
%%EndFeature

We tried this with the 3.0 version of xpdf as well as the built-in pdftops of cups 1.1.19.
