Indeed. A PostScript file is produced because the queue uses a PPD which
instructs it to do this.

Ghostscript cannot be removed - cups-filters depends on it. But you can
have it not being used on the testing client by setting a queue which
avoids filtering. This would bring it into line with the stable client's
queue, which I guess also avoids filtering. (You did not answer my query
in the last mail, lpoptions -p ...; that is why it is a guess).

1. Set up this queue:

      lpadmin -p testq -v ipp://192.168.1.100/printers/E460DN -E -m raw

2. Print:

      lp -d testq 158.pdf
