If the remote printer understands PS, then you should be able to just use lpr(1) to print postscript files directly to it: no need for local invocation of Ghostscript to convert the data into PCL. (Note that lp(1) is supplied as a compatability shim for Posix 1003.2 compliance, and it's just the familiar BSD lpr(1) command in disguise.) If gs is going to be involved in printing documents, then it's more usually used as a print filter, invoked by the lpr system automatically. If you install the print/apsfilter port, it will run a setup script to configure itself, install the needed print filters and generate the necessary /etc/printcap -- works very nicely, and autodetects quite a number of different file formats which it will transparently convert to postscript for you. As for the command line you show -- I think something like the following is possibly what you intend: % gs -q -dNOPAUSE -sDEVICE=3Dljet4 -sOutputFile=3D- ./file.ps | lpr -Pp= rinter Cheers, Matthew --=20 Dr Matthew J Seaman MA, D.Phil. 26 The Paddocks Savill Way PGP: http://www.infracaninophile.co.uk/pgpkey Marlow Tel: +44 1628 476614 Bucks., SL7 1TH UK --LyciRD1jyfeSSjG0 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (FreeBSD) iD8DBQFAxt9giD657aJF7eIRAo0OAJ9l6KD/MeI2RK30/UkahZ5kmUsOwACfVATo 4am2NbPQTLz3CpXvZTlQJ6c= =5gBV -----END PGP SIGNATURE----- --LyciRD1jyfeSSjG0--
