How to find IP address of connected device? (Ricoh Laser AP2600 printer)

I've connected my MacBook Pro to a working Ricoh Laser AP2600 printer via Ethernet cable.

After installing the appropriate drivers and settings and still being unable to print, at someone's suggestion I tried "pinging" the printer to see if the computer "sees" it, and found the answer was "No." The Network Utility produced this result:

"PING 011.022.033.044 (9.18.27.36): 56 data bytes
Request timeout for icmp_seq 0
Request timeout for icmp_seq 1
Request timeout for icmp_seq 2
011.022.033.044 ping statistics ---
4 packets transmitted, 0 packets received, 100.0% packet loss"

In order to set up the printer in Snow Leopard's "Print & Fax" System Preferences pane, I had to find and then manually enter the Ricoh's IP address.

The Ricoh Laser AP2600 has a pretty primitive interface display, but I had been able to navigate through its menus like so: Menu/Host Interface/Network Setup/IP Address to find what is listed as the printer's "IP Address": 011.022.033.044 . That is what I entered when I set up the printer on the MacBook Pro.

However, considering that Ping was unsuccessful at contacting the printer at that address, and considering that 011.022.033.044 seems more like some kind of default setting that an actual IP address, I have the feeling that this is not the printer's IP address after all.

But then, how can I find it? No matter where I scroll around in the Ricoh's small display, I can find no other mention of what its IP address may be aside from 011.022.033.044. A Web search reveals just about nothing on this topic, as Ricoh Laser AP 2600s are at least 20 years old and very little info is available about them on the Web.

Is there some way for me to uncover the Ricoh's IP address using some tool on my computer while connected to the printer? Could it conceivably be stamped in some hidden place on the case? Is it findable on the Web? Or...? (And what does "(9.18.27.36)" refer to it the Ping results?) Otherwise, without knowing the IP address, there seems to be no way to connect to it with 10.6.3's setup.

(Note: I still have an old PowerBook running 10.4.11, and with that I can connect to and print with the Ricoh problem-free (using the same cable)! The reason being that I did not need to know the IP address, but connected to it via "AppleTalk," which seems to be no longer an option in 10.6.3 for connecting to printers.)

Any help would be much appreciated.

15" MacBookPro, Mac OS X (10.6.3)

Thanks. I downloaded WakeOnLAN and it detects a device with the IP address "169.254.220.56" which appears in the list of detected devices when I plug in the Ricoh printer's Ethernet cable and disappears when I unplug it. The same address appears and disappears in "Network Utility's" Info pane when I plug in and unplug the cable. Thus, I can only come to the conclusion that "169.254.220.56" is the Ricoh's IP address.

Strangely, however, in WakeOnLAN's list, it give my MacBook's name (and not the name of any Ricoh printer) as the name of the device with the "169.254.220.56" IP address - in fact, my MacBook is listed in WakeOnLAN twice, once with its correct normal address, and once with 169.254.220.56. Am I to assume that WakeOnLand just assigns my computer's name to the detected 169.254.220.56 adddress because it can't find any other name for the device? Or...?

Anyway, assuming that 169.254.220.56 is the correct IP address for the printer, I tried it out, and unfortunately was still unable to make it work. I tried to print using this new 169.254.220.56 IP address with no success. I tried creating not just one but SIX new "printers" in the "Print & Fax" SysPref pane. All of the printers used the 169.254.220.56 IP address, but I tried it six different ways:

LPD Line Printer Daemon with Ricoh's custom printer driver
IPP Internet Printing Protocol with Ricoh's custom printer driver
HP Jetdirect-Socket with Ricoh's custom printer driver

LPD Line Printer Daemon with Apple's "Generic PostScript" printer driver
IPP Internet Printing Protocol with Apple's "Generic PostScript" printer driver
HP Jetdirect-Socket with Apple's "Generic PostScript" printer driver

NONE of them worked, but they all gave the following error message when I tried to print:

"Network Host "169.254.220.56" is busy; will retry in 5 (10,15, etc.) seconds."

However, as fas as I can tell, the printer isn't busy: its green "ready to print" light is illuminated and the printer screen says "Ready," and no one else is using it.

I guess my original question has (I assume) now been answered, but if anybody knows how to use this info to make my printer work, I'd love to hear your suggestions!

The mac won't talk to the printer unless they're on the same subnet, or there's a route between them. Addresses in the 169.254 range are usually "self assigned", meaning there was no static address set and nothing assigned via DHCP or bootp.

If your printer address really defaults to 11.22.33.44, then you can set an address on your computer to something on the same subnet -- like 11.22.33.45 with a netmask 255.255.255.0. Then you should be able to ping the printer.

Either assign your IP addresses statically or figure out why you're not getting them dynamically.

Thanks very much for your help.

I did exactly what you suggested:

In System Preferences > Network, with the Ethernet cable connected and the printer on, I selected the Ethernet port in the list and in the "Configure IPv4" menu I changed 'DHCP' to 'Manually' to an IP address of 11.22.33.45 and a subnet mask of 255.255.255.0. I left the other settings empty and "applied" the information. I then tried to Ping the printer's IP address of (at first) 11.22.33.44 and then (just in case) 011.022.033.044. Unfortunately, neither worked -- 0% success rate with Ping. Ugh!

HOWEVER, I made another breakthrough while doing all this. I discovered that I can alter my printer's IP address to whatever number I want in the xxx.xxx.xxx.xxx format! And that it will "stick" between reboots and turning it on and off. Furthermore, I discovered I can alter my printer's
Subnet Mask
Gateway Address
Access Control
Access Mask
to whatever number I want in the xxx.xxx.xxx.xxx format.

As an experiment, I changed the printers settings to these numbers:
IP Address: 014.022.033.044
Subnet Mask: 255.255.255.000
Gateway Address: 255.255.255.000
Access Control: 255.255.255.000
Access Mask: 255.255.255.000
(they formerly all had been 000.000.000.000)

I then went to SysPref>Network and under "Manually" in "Configure IPv4" I changed the address to 014.022.033.045 and the Subnet Mask to 255.255.255.000 and "applied."

Then I tried pinging again: Zilch! Then I tried changing the SysPref IP Address to simply 14.22.33.44 with same subnet mask, applied, then Pinged again. Fail! 100% packet loss.

So, perhaps I'm making progress toward figuring this out. Or not.

Considering that I have the ability to set the printer's settings any way I want (also: The printer's "Ethernet" setting is on "auto," but I could choose 10mbps or 100mbps if that's helpful; also, the "Active Protocol" is set to "TCP/IP"), and that the settings get retained in its memory permanently, what steps could I take to connect to it, considering all the failed dead-end experiments described above (which seem to have exhausted a lot of my options). Thanks!
