APSFILTER(1)                 General Commands Manual                APSFILTER(1)

NAME
     apsfilter — magic print filter with auto file type recognition

SYNOPSIS
     lpr [-Pprinter] [-C option1:...:optionN] [file ...] (lpd style)
     lpr [-Pprinter] [-Z option1:...:optionN] [file ...] (LPRng style)
     lp [-d printer] [-o option1:...:optionN] [file ...] (Solaris style)

DESCRIPTION
     Apsfilter is a magic print filter which allows you to print different
     document types “automagically” without having to convert them manually into
     a document format which is understood by your printer hardware.

     Apsfilter uses third-party software to convert every supported file type
     into PostScript (PS) first. If you have a real PS printer, the data stream
     is then sent directly to the PS printer, otherwise it is piped through the
     famous PS interpreter gs(1) which supports a wide range of output devices.

     Thus the question whether a particular printer is supported by apsfilter is
     actually the question of it either understanding PS directly, or being
     supported by gs(1) in some way (possibly using some emulation of another
     printer's software interface, like Epson's ESC/P2 or HP's PCL).

     Another important thing to remember is that the required driver support has
     to be present in the installed gs(1) binary.  gs -h lists (among others)
     which drivers are currently compiled in. SETUP warns when a selected driver
     is missing and guides in choosing another driver.

     The FreeBSD ports collection offers an easy and comfortable framework for
     FreeBSD users to configure and install apsfilter, gs(1), gs third-party
     driver and filter programs for their personal needs.

     The apsfilter script is designed to avoid temporary files as much as
     possible. So it is very efficient in use and doesn't fill up filesystems
     even when printing large printjobs in high resolution and best print
     quality.

     Apsfilter offers a wide range of customization options through config files
     and lpr(1) command line options, see below.

   Advantages over other magic filters
     Apsfilter and its SETUP is completely written in a script language (see
     sh(1) ). So it is easy to understand and modify even for users and admins
     who are quite new to the Unix business.

     Apsfilter is highly customizable and its developement since 1994 has shown
     that it scales very well with the still growing demand of additional
     features.

   Supported printers
     Apsfilter supports locally connected serial, parallel and USB printers.

     Remote printing cababilities: Unix remote printing (lpd protocol), printing
     to an AppleTalk remote printer via pap(1) as well as Windows remote
     printing via SAMBAs smbclient(1) on Windows 95/98/NT/2000 printer as guest
     user or using a real password protected Windows account.

     Apsfilter 's SETUP utility supports in installing all supported printer
     types, no matter if local or remote printer, into the printer capability
     database /etc/printcap.

   Supported file types
     ar, arc, arj, ASCII, BMP, CAB, cpio, DATA, DVI, FBM, FIG, FITS, GIF, Group
     3 FAX, HTML, IFF ILBM, JPEG, Kodak Photo CD (PCD), LHA, MGR, MIFF, PAM,
     PGM, PBM, PNM, PPM, PDF, PNG, Postscript (PS), RAR, RLE, RPM, SGI, Sketch,
     Sunraster, TAR, Targa (TGA), TIFF ROFF, WMF, WorPerfect graphics, XCF, X
     Pixmap (XPM), X Window dump (XWD), ZIP, ZOO.  Note that actual support
     depends on the installed filter programs.

   Installation
     Extract the tarball and execute ./configure in the apsfilter directory
     (maybe with some options; use ./configure --help to see a listing).

     After that, login as root and call make install; then you can set up
     printers with /usr/local/share/apsfilter/SETUP.

     SETUP adds the printer to the /etc/printcap database to make it available
     to the lpd(8) print spooler, and configures apsfilter for operation with
     that printer.

     After successfull installation, SETUP remembers its previous configuration
     settings in a file called SETUP.cfg.

   Command line options
     Several command line options to apsfilter are available which allow the
     user to influence the printing quality, color mode, paper size etc. The
     handbook includes a detailed listing.

     draft                  Draft quality.

     lo|low                 Low quality.

                            print Postscript source code without actually
                            interpreting it.

     raw                    Pass-through mode, your print data won't be changed

     landscape|portrait     Paper orientation.

     book                   Output pages in "book" format, implies
                            "2pps,duplex,shortbind"

     duplex|simplex         Whether to use duplex mode or not.

     copies=N               Number of copies.

EXAMPLES
           lpr -C high:color:glossy file.gif tex.dvi.gz file.html ...

     prints some files of different types no matter whether compressed or not on
     the Unix default printer (see lpr(1) ).

     The -C option to the lpr command sets additional ghostscript driver-
     specific options.  Here, ‘high’ means high resolution (e. g. 600 dpi for an
     HP Printer using gs's “cdj850” printer driver), color output (e.g. 32 bits
     per pixel), and the paper type is set to glossy paper

           lpr -C duplex somefile

     enables pseudo duplex printing by halting the print queue after printing a
     documents even pages and so giving the user a chance to flip paper and
     restart printing after executing a special user command on the command
     line.

     User gets a notification mail containing a session oriented magic wakeup
     command and key which restarts printing of the odd pages of the print job.

     The so called magic command makes sure that only the initiator of the print
     job is able to restart printing after reinserting the paper.

     Beware, if you have nasty users, this can cause print jobs to hang, filling
     up the print queue and at least the /var file system.

BUGS
     See apsfilter software center - http://www.apsfilter.org/ - for new
     versions, bugfixes and known bugs.

     Please use the new tool apsfilter-bug(1) to release bug- or problem
     reports. It automatically presents you a form in an editor window which
     asks you some standard questions.  If you save and quit the editor session,
     then this report is sent automatically via e-mail to the proper apsfilter
     mailinglist.

     If apsfilter fails to print something or prints it in a way you wouldn't
     expect and you want to report an apsfilter error then please save the
     debugging output of one print session using the new aps2file(1) utility by
     typing aps2file -D -Z options file > /dev/null 2> file.debug and including
     the debugging output in the file file.debug into the edit session of the
     apsfilter-bug utility, so that it is included into the mail to the
     apsfilter mailinglist.

     Please note that you need to run /bin/sh (Bourne Shell), bash or a
     compatible shell, so that the above mentioned output redirection works.
     Under C-shell (/bin/csh) or tcsh it would't work. If you don't know, then
     simply make sure you use the Bournce shell by typing /bin/sh or bash, then
     you should have no problems with redirection of stdout and stderr (>
     /dev/null 2> file.debug).
