    Hi, welcome to the apsfilter setup and thanks for using apsfilter!

    Before we begin with the setup, I'd like to make you familiar
    with the apsfilters license:
    1. apsfilter follows the GNU public license (GPL), see copyright
    2. and this little "Postcard License":

	"I'd like to get a postcard from you! I'm interested in,
	 who is using apsfilter, where you live, and where in the
	 world apsfilter is doing it's job."

    Please send me an e-mail to  apsfilter-snailmail@apsfilter.org  to
    get my postal address; we'll get there later in this setup...

		- creating printer spool directories as needed
		- auto-creation of printcap config-file
		  for apsfilter (add / overwrite printer)
		- setting up apsfilter (which gs driver to use,
		  paper size, print resolutions and color depth)
		- printing a test page (settings may be modified
		  until successfull ouput of a testpage)
		- saves some SETUP settings in apsfilterrc config file

        it does not:

		- complete printer management in printcap

    Attention 
    =========
    As I see now, you are installing apsfilter for a printer that needs
    gs (ghostscript) as postscript emulator, but apsfilter's SETUP was
    unable to locate the ghostscript emulator.

    One reason might be that ghostscript is installed in an unusual
    directory and SETUP was unable to auto-detect this path.

    Then please add this path at the top of SETUP and run it again.

    Otherwise you have to get the ghostscript sources and fonts
    and install ghostscript by hand and run setup again afterwards.

        ----------------------------------------------------------------

	The Baud Rate is the transfer rate at which the asynchronous
	serial interface is sending bits from the computer to the printer.

	The higher the Baudrate the better and shorter your cable should
	be. I recommend 5m cable as a maximum for 38400 Baud and perhaps
	2-3m for speeds higher than that. It depends heavily on the
	quality of your cables, interfaces, handshaking and printer.

	Another rule of thumb is, that hardware handshaking works best
	with higher Baudrates, but needs a special cable depending on
	your machine and the printer.

	Valid and useable Baudrates are (a good starting point is 9600)

	1) 4800		2) 9600		3) 19200
	4) 38400	5) 57600	6) 115200

	Please note: you have to configure your printer as well for that
	speed and don't forget to power off and on the printer after that.

        A P S F I L T E R   Serial Interface Settings  -- Handshaking --
        ----------------------------------------------------------------

	There are two possible handshaking methods, often called
	Hardware and Software handshaking. This determines, how
	the printer tells your computers start or stop sending data
	to avoid data lossage.

	Directly forget about using ghostscript as Postscript Emulator
	with the software handshaking (xon/xoff protocol), because gs
	(ghostscript) sends a binary data stream to the printer containing
	these start/stop characters. But I will allow you to select this
	as an option, you'll certainly know better than I what you want.

	Hardware handshaking isn't as standardized as it could. So
	different computer/printers use different pins/signals of the
	serial interface, to stop/start the data transfer. You'll
	certainly need a special printer cable !

	1 - software handshaking (xon/xoff, 3 wires, avoid this)
	2 - hardware handshaking (crtscts, RTS/CTS flow control)

	The easiest way, to connect a printer to your computer is by
	using the parallel interface, because it's usually *faster*,

	When configuring a serial printer, the installation dialogue
	asks you many questions about how to configure the serial
	interface of your computer, so that it works well with your
	printers current settings.

	When using the serial interface, then you have to choose special
	cables, depending on the communication protocol between computer
	and printer (hardware/software handshaking). Many pitfalls here !

	In most cases it's relatively easy to choose a suitable
	ghostscript driver from the list of supported printers.

	If you're printer is not in the list of supported printers:
	    - guess a suitable driver by "trial and error"
	    - consult your printers handbook to what ghostscript printer
	      driver your printer "claims" to be compatible

	If this test produces unacceptable results, then please choose
	another driver or try another (perhaps lower) print quality,
	because it might be a memory problem. Only use print resolutions
	that are supported by your printer, consult the printers manual!

	Creating the test output might take some time, please be patient.

To let the printer scheduler know of the new printers, it has to be
restarted. Be sure that no print jobs are in the queue.

For LPRng use:  lpc reread
For *BSD  use:  lpc restart all

For Linux BSD-lpr use the vendor supplied script, i.e.:
    /etc/rc.d/init.d/lpd restart
or similar.

	New CLASS support (lpr -C) allows you to set one more more options
	for gs (PS Emulator), separated by colons (":").

	CLASS support is currently available for some gs drivers. Look into
	apsfilter script, which driver dependent options are supported.

	Example: stcolor print driver: set 
		- print resolution to high resolution (720dpi)
		- color depth to 30 bits per pixel

	For printing ASCII files apsfilter now uses a2ps V. 4.12 or higher.
	Old patched a2ps and rewindstdin have gone!

	You can also use mpage or recode; see apsfilterrc for this setting.

	remote printing is fully supported by apsfilter:
	- on Unix remote printer (lpd) and
	- Windows 95/98/NT/2000 Remote Printer

You need SAMBAs smbclient utility, to print on Windows remote printer.
SETUP makes the necessary entries in printcap(5).

You need a line printer scheduler (fixed lpd or LPRng) on your system
that allows to use input filters (printcap: if=...) when printing
to remote printers (printcap: rm:..., rp:...)

FreeBSD 3.x and later have a fixed lpd, no problem here.

Otherwise use the lpd successor LPRng (lineprinter next generation)
or configure lpr.conf in the lineprinters spool directory (new!)

Apsfilter can be installed on a Server or Desktop machine. Best is to install
it on a dedicated Server, where printers are locally connected to, since
ghostscript Postscript emulation might become a CPU intensive process. The
faster the CPU, the faster the Postscript emulation and printing in general.

If you want to print on Network printer using the lpd protocol, you should
install apsfilter on a machine which has a fixed lineprinter scheduler and
is able to use input filters (apsfilter) when printing to a remote printer.
FreeBSD 3.x and later has a fixed lpd, otherwise use the lpd successor LPRng.

Since apsfilter 5.2.0 you can also print to Windows remote printers, that
are printers on Windows machines, which are shared in the network. You need
to install SAMBA on the Unix apsfilter hosts, who want to use Windows printers.
