I finally got round to reconnecting our printer to a linux system. Same problem, it's hashing large blocks of colour.
What do you mean "Use 8.54+ with Well Tempering Screening."? (sorry if it's a stupid question :S)
I downloaded the file you sent, and ran the command on it.. this is what was returned:
root@scalix:~# foo2hp2600-wrapper -c pic.ps > pic-gs854-Qwts.zc
/usr/bin/foo2hp2600-wrapper: line 298: pic.ps: No such file or directory
