     apsfilter — magic print filter with auto file type recognition


     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)


     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

     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

     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
     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.

     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

     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.

     ascii                  Force printing as ASCII document. For example to print Postscript
                            source code without actually interpreting it.

     raw                    Pass-through mode, your print data won't be changed by any filter.

                            Paper size.

                            Text file filter to use, when printing ASCII documents.

     tray0...tray9          Paper feed tray number.

     pretty=N               highlight level for pretty-printing (N=0,1,2)

     header|noheader        Whether you want headers in your text prints.

     border|noborder        Whether you want borders in your text prints.

     1pps|2pps|4pps|8pps    Pages per sheet.

     landscape|portrait     Paper orientation.

     duplex|simplex         Whether to use duplex mode or not.

     shortbind|longbind     Paper binding edge.

     copies=N               Number of copies.


           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.

     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

     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).
