I first run
  PPD=/etc/cups/ppd/isc2428ps.ppd /usr/lib/cups/filter/texttops [....]
and got the  "output-from-pstops.prn".

next I run
  PPD=/etc/cups/ppd/isc2428ps.ppd /usr/lib/cups/filter/foomatic-rip 1 2 3 4 5 output-from-pstops.prn

Then the error :

and I find the "unable to create Job object err=3" is printed by hpijs...  and the return value indicate when alloc mem failed..
But I have very enough mem , and if run gs derectly instead of foomatic-rip , there will be no error...
I'm so confused...

BTW: my system doesn't has usr lp.
