NAME

       papd.conf - Configuration file used by papd(8) to determine the configuration of printers used by the
       Netatalk printing daemon

DESCRIPTION

/etc/netatalk/papd.conf is the configuration file used by papd to configure the printing services offered
by netatalk. Please note that papd must be enabled in /etc/netatalk/netatalk.conf for this to take any
effect. papd shares the same defaults as lpd on many systems, but not Solaris.

Any line not prefixed with # is interpreted. The configuration lines are composed like:

printername:[options]

On systems running a System V printing system the simplest case is to have either no papd.conf, or to
have one that has no active lines. In this case, atalkd should auto-discover the local printers on the
machine. Please note that you can split lines by using \\fR.

printername may be just a name (Printer 1), or it may be a full name in nbp_name format (Printer
1:LaserWriter@My Zone).

Systems using a BSD printing system should make use of a pipe to the printing command in question within
the pr option (e.g. pr=|/usr/bin/lpr).

When CUPS support is compiled in, then cupsautoadd as the first entry in papd.conf will automagically
share all CUPS printers by papd utilizing the PPDs assigned in CUPS (customizable -- see below). This can
be overwritten for individal printers by subsequently adding individual entries using the CUPS queue name
as pr entry. Note: CUPS support is mutually exclusive with System V support described above.

The possible options are colon delimited (:), and lines must be terminated with colons. The possible
options and flags are:

am=(uams list)
The am option allows specific UAMs to be specified for a particular printer. It has no effect if the
au flag is not present or if papd authentication was not built into netatalk. Note: possible values
are uams_guest.so and
uams_clrtxt.so only. The first method requires a valid username, but no password. The second
requires both a valid username and the correct password.

au
If present, this flag enables authentication for the printer. Please note that papd authentication
must be built into netatalk for this to take effect.

co=(CUPS options)
The co option allows options to be passed through to CUPS (e.g. co="protocol=TBCP" or co="raw").

cupsautoadd[:type][@zone]
If used as the first entry in papd.conf this will share all CUPS printers via papd. type/zone
settings as well as other parameters assigned to this special printer share will apply to all CUPS
printers. Unless the pd option is set, the CUPS PPDs will be used. To overwrite these global settings
for individual printers simply add them subsequently to papd.conf and assign different settings.

fo
If present, this flag enables a hack to translate line endings originating from pre Mac OS X
LaserWriter drivers to let foomatic-rip recognize foomatic PPD options set in the printer dialog.
Attention: Use with caution since this might corrupt binary print jobs!

op=(operator)
This specifies the operator name, for lpd spooling.

pa=(appletalk address)
Allows specification of Appletalk addresses. Usually not needed.

pd=(path to ppd file)
Specifies a particular PPD (printer description file) to associate with the selected printer.

pr=(lpd/CUPS printer name or pipe command)
Sets the lpd or CUPS printer that this is spooled to.

EXAMPLES

Unless CUPS support has been compiled in (which is default from Netatalk 2.0 on) one simply defines the
lpd queue in question by setting the pr parameter to the queue name, in the following example "ps". If no
pr parameter is set, the default printer will be used.

Example. papd.conf System V printing system examples

The first spooler is known by the AppleTalk name Mac Printer Spooler, and uses a PPD file located in
/usr/share/lib/ppd. In addition, the user mcs will be the owner of all jobs that are spooled. The second
spooler is known as HP Printer and all options are the default.

Mac Printer Spooler:\
:pr=ps:\
:pd=/usr/share/lib/ppd/HPLJ_4M.PPD:\
:op=mcs:

HP Printer:\

An alternative to the technique outlined above is to direct papd´s output via a pipe into another
program. Using this mechanism almost all printing systems can be driven.

Example. papd.conf examples using pipes

The first spooler is known as HP 8100. It pipes the print job to /usr/bin/lpr for printing. PSSP
authenticated printing is enabled, as is CAP-style authenticated printing. Both methods support guest and
cleartext authentication as specified by the ´am´ option. The PPD used is /etc/atalk/ppds/hp8100.ppd.

HP 8100:\
:pr=|/usr/bin/lpr -Plp:\
:sp:\
:ca=/tmp/print:\
:am=uams_guest.so,uams_pam.so:\
:pd=/etc/atalk/ppds/hp8100.ppd:

Starting with Netatalk 2.0 direct CUPS integration is available. In this case, defining only a queue name
as pr parameter won´t invoke the SysV lpd daemon but uses CUPS instead. Unless a specific PPD has been
assigned using the pd switch, the PPD configured in CUPS will be used by papd, too.

There exists one special share named "cupsautoadd". If this is present as the first entry then all
available CUPS queues will be served automagically using the parameters assigned to this global share.
But subsequent printer definitions can be used to override these global settings for individual spoolers.

Example. papd.conf CUPS examples

The first entry sets up automatic sharing of all CUPS printers. All those shares appear in the zone "1st
floor" and since no additional settings have been made, they use the CUPS printer name as NBP name and
use the PPD configured in CUPS. The second entry defines different settings for one single CUPS printer.
It´s NBP name is differing from the printer´s name and the registration happens in another zone.
