I am trying to make a list of all AirPrint printers on the network at a school. We have many of them because of all the classroom and office printers, but they have not been set up with meaningful names. I tried reading the DHCP allocation table in the router, but many of the printers do not report a host name. I can't check printers in-person because of the disruption to classes from going in to every room and playing with the 1-3 printers there.

The dns-sd command as in How to find IP address of my other Mac? gives a column called Instance Name, rather than the host name. Using the dns-sd -G option on the instance names gave no such record.

dns-sd -Z is closer, since it gives host names to look up with the G option, but it doesn't give a complete list. There are many more printers in the Add Printer dialog on a Mac than there are in the output of dns-sd -Z.

Does anyone have some code or script to just find all the IP addresses of things advertising by Bonjour?

    Try Bonjour Browser - tildesoft.com. Are your printers from a single manufacturer, and if so which one? We've a number of Epson AIO units around campus and each time we deploy a new unit we record the serial and location. We then use Epson's EpsonNet Config to give printers Bonjour names and locations, all relatively painless. Unfortunately any large deployment is going to cause some initial unavoidable pain but this can be mitigated somewhat if the manufacturer has admin/config tools available.

  • Nearly all HP here. No consistency in models or even model lines though, we have things varying from home printers to small office sized. Bonjour browser seems to work, I've had a look at that and it's showing IPs for tons of printers. Commented Mar 5, 2015 at 20:45
  • Out of curiosity...what good is a list if you don't know where they are deployed, what their SN# is, etc? Are these printers getting static IP address?

  • There are more printers in the Add Printer dialog than you see with dns-sd -Z for this reason: every AirPrint-capable printer is also IPP-capable. But not every IPP-capable printer is AirPrint-capable (or has AirPrint disabled). For more details, see my answer. Commented May 22, 2016 at 19:19

I do not have an AirPrint printer on my network. And never played with one either...

I cannot test with a real AirPrint device in my proximity right now.

But here is how I can list all the IPP-enabled printers (in this case they are all connected via CUPS):

First, browse for DNS-SD discoverable services (all types):

kp@zdv-wireless-43-219:> dns-sd  -B  _services._dns-sd._udp  local.

  Browsing for _services._dns-sd._udp.local.

  23:54:37.798  Add     3   4 .       _tcp.local.          _afpovertcp

  23:54:37.798  Add     3   4 .       _udp.local.          _net-assistant
  23:54:37.798  Add     2   4 .       _tcp.local.          _eppc

So yes, there is indeed an IPP print service (but no AirPrint one, which would be marked by stand out being tagged as Service Type of _airprint._tcp in the list).

Second, browse for all present services of type "IPP":

kp@zdv-wireless-43-219:> dns-sd  -B  _ipp._tcp  local.

  Browsing for _ipp._tcp.local.
  DATE: ---Fri 20 May 2016---
  23:54:47.782  ...STARTING...
  Timestamp     A/R  Flags  if Domain  Service Type   Instance Name

  23:54:47.783  Add      2   4 local.  _ipp._tcp.     Officejet 6600 @ mbp

Ok, one of the instance names is "Officejet 6600 @ mbp".

Third, lookup specific info about the printer named "Officejet 6600 @ mbp":

kp@zdv-wireless-43-219:> dns-sd  -L  "Officejet 6600 @ mbp"  _ipp._tcp  local.

  Lookup Officejet 6600 @ mbp._ipp._tcp.local.

        printer-state=3 printer-type=0x480900E

Half of the info you are looking for (hostname of the printer) is covered by the sentence "Officejet\0326600\032@\032mbp._ipp._tcp.local. can be reached at mbp2-2.local.:631"

This gives the current (Bonjour-)hostname of node offering the looked-up print service.

Fourth, look up the IPv4 and IPv6 addresses for a given hostname:

kp@zdv-wireless-43-219:> dns-sd -Gv4v6 mbp2-2.local

  DATE: ---Sat 21 May 2016---
  0:12:41.025  ...STARTING...

  0:12:41.025  Add  2  4 mbp2-2.local.                               120


Assuming my first command had returned some _airprint service available in my network, then my guess is that one of the returned lines would read:

00:00:00.000  Add     3   4 .       _tcp.local.          _airprint

Thus, my second command would have to be:

kp@zdv-wireless-43-219:> dns-sd  -B  _airprint._tcp  local.

I assume this could return something like

200:00:00.000  Add    3   4 local.  _airprint._tcp.  Some AirPrinter @ somehost

Then my third command should read:

kp@zdv-wireless-43-219:> dns-sd  -L  "Some AirPrinter @ somehost"  local.

Which would return a line telling you "... can be reached at somewhere.local.:1234". From which to derive the fourth command:

kp@zdv-wireless-43-219:> dns-sd  -Gv4v6  somewhere.local.  

Caveats: The last part, about AirPrint service discovery may be wrong. It could be the case that AirPrint services announce themselves just as standard IPP services do. You have to find out yourself. If you do, please report back.


I've googled a bit for "_airprint._tcp".

I didn't find a single instance of anybody who reported in some forum their output from dns-sd -B listing this particular string.

However, there were lots + lots of _airplay._tcp and _ipp._tcp results. This means that "_airprint._tcp" does not seem to exist, and AirPrint printers must be using a different signature to make themselves known to potential clients. However, we already know that all AirPrint services use IPP for communication with their clients, so they also MUST be making the _ipp._tcp service type announcements.

Hence it is safe to conclude that...

  1. ...all AirPrint devices will announce themselves as _ipp._tcp (not _airprint._tcp). Also, it looks like...
  2. ...you can identify AirPrint devices by looking for the TXT record of urf="$anything" and pdl="$anything,image/urf".

To verify this, I checked with what the (fake) announcement from dns-sd.org tells about its AirPrint (warning, it is not permanently on the Internet, sometimes it goes away for hours...). It does return this:

kp@zdv-wireless-43-219:>  dns-sd -Z _ipp._tcp,_universal dns-sd.org.

  Browsing for _ipp._tcp,_universal.dns-sd.org.

    "priority=10" "adminurl=http://www.dns-sd.org/ServerStaticSetup.html" \
    "note=At Stuart's house" "Color=T" "Duplex=F" "Scan=F"

Indeed, "Stuart's Home AirPrint Printer" mentions "URF" in its TXT records.

So, to summarize the answer to your question "How can I get the IP addresses of all AirPrint printers?"

  1. First, list all IPP printers.
  2. Second, exclude these IPP printers which do NOT enumerate the two above mentioned urf-entries in their TXT records.

Verify my statements

The following (minimal) command will announce a fake AirPrint device in your LAN (until you cancel the command with ^C):

dns-sd                                                                   \                                                                            
    -R "Minimal AirPrint Demo (dummy+fake printer fooling iPad clients)" \               
    _ipp._tcp.,_universal                                                \                                                              
    .                                                                    \                                                                                  
    631                                                                  \                                                                                
    pdl="image/urf"                                                      \                                                                    

Your iOS devices will now enumerate this printer amongst its auto-discovered AirPrint devices.

(BTW, you can announce the port as something different from 631 too -- the iOS clients will still identify it as an AirPrint device...)

Now repeat this little experiment, just leave one of the two image/urf or URF="" statements off your command:

  1. The fake device will still appear as an IPP printer in the DNS-SD/Bonjour browse lists.
  2. But iOS clients will only list as AirPrint-capable these (fake or real) devices with the "URF"-related entries.

Before you dive into the following answer:
Please make sure you've understood the comprehensive AirPrint explanations for the [AirPrint] tag info I've recently written.

There is another tool which can identify AirPrint devices. It is the little known ippfind utility, that ships as part of CUPS (on Debian: as part of the cups-client package).

There is an ippfind.exe utility available for Windows as well. It ships as part of the IPP Everywhere Selfcertification Software Package which is available for download from the Printer Working Group (PWG) website here:

So the following method works on Linux as well as on Mac OS X and Windows.

I'll show now step by step, how to work with it...

Most simple command finds all IPP printer URIs

The most simple way to execute the utility is this:


On my current system, it returns:


This is a list of all IPP print services (including the AirPrint ones). Note how some of these do not use the default IPP port 631, but they are still discovered.

Because ippfind didn't see any command line parameters, it silently used its default ones, and in reality this command did run:

ippfind _ipp._tcp --print

Filter out the AirPrint devices

To narrow down from all IPP printers to only those which support AirPrint, we have to add the subtype _universal to our query:

 ippfind _ipp._tcp,_universal --print

This leaves me with the following subset of the full list from above:


Get the host names for the IPP URIs

ippfind works similar as the classical find utility which searches for files, directories and other objects in the file system hierarchy, and therefor has a --exec parameter, which can be used to run a command against each found item:

 ippfind _ipp._tcp,_universal --exec echo '{service_hostname}' \;

The command returns the host names for all the AirPrinters. It does not list the other, non-AirPrint IPP printers:


Find the IP addresses of all AirPrint devices

Since from previous answers we already know that dns-sd -G will return the IP addresses, we can execute this instead of the simple echo command from above:

ippfind _ipp._tcp,_universal --exec dns-sd -G v4 '{service_hostname}' \;

    DATE: ---Tue 24 May 2016---
     3:39:18.024  ...STARTING...
    Timestamp     A/R Flags if Hostname         Address          TTL

     3:39:18.028  Add     2  4 mbp2-3.local.   120
     3:39:18.028  Add     2  4 mbp2-7.local.   120

Voila!, a list of IP addresses alongside the fully qualified (Bonjour) host names....

You could of course also run something like:

ippfind _ipp._tcp,_universal --exec echo  '{service_hostname}' \;  \
    | while read line; do ping -c 1 "$line" ; done                 \
    | grep PING

PING mbp2-2.local ( 56 data bytes
PING mbp2-3.local ( 56 data bytes
PING mbp2-7.local ( 56 data bytes

(for example, if dns-sd is not readily available, like on Windows), and it will also report the IP addresses (simply because ping needed and resolved them and also reports them).

(I admit: I did not test this with real AirPrint devices -- I simply have none available. I did it with simulated ones. But I would be surprised if this didn't work as well in the environment the OP works with...)


There's a fairly painless way of doing this with the perl module Net::Bonjour:


use Net::Bonjour;
use warnings;
use strict;

my $res = Net::Bonjour->new('printer');

print "Name\t\t\tAddress\tPort\n";
foreach my $entry ( $res->entries) {
    print join ("\t", $entry->name , $entry->address , $entry->port) , "\n";

This will list the names, ip addresses and ports of all the Bonjour enabled printers on the network, not just the AirPrint ones. It works on Mac, Windows and Linux.

Here is another answer. It's shorter, and more direct to the point. However, I'll let the first answer stand on its own, since it may be useful for people who are exploring this topic.

Currently, I only know an answer for Linux.... If I find a command for Mac + dns-sd, I'll extend this answer.

On Linux, run this command:

kp@zdv-linux-003:>  avahi-browse -rt _universal._sub._ipp._tcp

     port = [632]
     txt = ["URF=V1.2,DM3,OF1-2-3-4,CP99,W8,OB10,PQ3-4-5,ADOBERGB24,DEVRGB24,DEVW8,SRGB24,IS1-2-4,MT1-2-3-5-12,RS600" \

            "ty=Kurt Pfeifle Handmade Model" "rp=printers/DummyAirPrint" \
            "qtotal=1" "txtvers=1"]

As you can see, the service type _universal._sub._ipp._tcp will display AirPrint devices, and the -r parameter will resolve it and reveal the IP address
