Q: Printing to a LaserWriter 12/640
-
Jun 9, 2011 5:33 PMby PAHU,Hello again Steve.
My first suggestion would be to open Network Utility and select the Info tab. This will show what IP address the Mac is currently using (you may have to change the drop menu from Ethernet to Airport depending on what connection method you are using on the Mac). If the Mac is set to 192.168.0.x, where x will be a different number to 123 which the printer is using, then this is a good start. If it is set to a different IP subnet, that is one or all of those first three sets of numbers is different to the printer then this explains the error and you will need to change the IP address of the Mac or printer.
If the IP address of the Mac is correct then still in Network Utility, select the Ping tab and enter 192.168.0.123 and set the number of pings to 4 (you don't need 10). Then click the Ping button and watch the response. If the Mac can 'see' the printer then the response should be something like:
PING 192.168.0.123 (192.168.0.123): 56 data bytes
64 bytes from 192.168.0.123: icmp_seq=0 ttl=255 time=3.582 ms
But if you get a reply along the lines of unable to connect then there is either an issue with the network card in the Mac or printer. Assuming that you were able to connect to the Internet using this Mac to post this question then this would suggest the Mac is fine and the printer is at fault. So using the eMac try the same Ping test to the printer. If the eMac also fails to get a reply from the printer then try turning off the printer power for a minute and check its network cable. With the printer back on try the Ping test again. Until you get a reply from the printers IP address then you won't be able to print to it.

Jun 9, 2011 10:30 PMby Stephen Schulte2,Thanks for the fast and informed reply, Pahu!!
What bugs me is that this works for over a year and then suddenly stops working. OK Here's what I did (following your instructions):
1. The IP address given as the Apple LaserWriter 12/640PS (hereafter referred to as LW) when the LW is turned-on and the first info-sheet prints out is: 192.168.0.123. In Network Utility the MacBook Pro-13" (MBP) shows 192.168.0.2 with the "router" (combined VOO ISP Modem and 4-port router since 8 March 2011 and it has worked fine to print since then up to yesterday).
2. OK so now I do the "pings":
A. I PING 4 times 192.168.0.123 (the LW): My reply: (This was actually the second time, the first time it was the same but the lines 2, 3 and 4:
ping: sendto: No route to host
ping: sendto: Host is down
ping: sendto: Host is down
Did not appear the first time but everything else the same, i.e. it was not reaching the LW printer:
Ping has started…
ping: sendto: No route to host
ping: sendto: Host is down
ping: sendto: Host is down
PING 192.168.0.123 (192.168.0.123): 56 data bytes
Request timeout for icmp_seq 0
Request timeout for icmp_seq 1
Request timeout for icmp_seq 2
--- 192.168.0.123 ping statistics ---
4 packets transmitted, 0 packets received, 100.0% packet loss
2. I now pinged the Canon MP640 printer at: 192.168.0.3 and got this result:
Ping has started…
PING 192.168.0.3 (192.168.0.3): 56 data bytes
64 bytes from 192.168.0.3: icmp_seq=0 ttl=64 time=0.477 ms
64 bytes from 192.168.0.3: icmp_seq=1 ttl=64 time=0.505 ms
64 bytes from 192.168.0.3: icmp_seq=2 ttl=64 time=0.508 ms
64 bytes from 192.168.0.3: icmp_seq=3 ttl=64 time=0.403 ms
--- 192.168.0.3 ping statistics ---
4 packets transmitted, 4 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 0.403/0.473/0.508/0.042 ms
So that printer is recognized (and works fine) -- so I am thinking the Ethernet card on the relatively new Mac is fine - I also pinged the Mac itself (192.168.0.2) and got a positive reply.
OK but now what? Can an ethernet card on the LW printer just fail from one day to the next?
Really appreciate any comments on next steps here.
Best regards,

Jun 10, 2011 12:04 AMby Stephen Schulte2,Additional Information after my reply above:
I now see that my IP addresses to which I get a positive reply are:
"Router": (VOO Modem): 192.168.0.1
MacBook Pro-13": 192.168.0.2
Canon MP640: 192.168.0.3
eMac in Carine's room: 192.168.0.4
AND when I do a PING to 192.168.0.5 - I get positive feedback, but not to 192.168.0.6 or other number...
Apple LaserWriter 12/640 PS: 192.168.0.123 - is the setting when the sheet prints out, but it seems the IP address needs to be 192.168.0.5
SO is the only way to get this to work to go back to my G4-733 running OS 9.2.2 and reconnect the LW to it and change the IP address to 192.168.0.5 ?
If so, would you believe it, I don't seem to have saved the procedure on how to do that--
OK I'll wait for a reply and also look for any notes on how I did that over a year ago when I moved to Snow Leopard. (I do have the LW manual - maybe something there?)

Jun 10, 2011 1:13 AMby PAHU,Hi Steve,
Thanks for doing the ping tests. It does appear that something is amiss with the LW. And changing its IP address to 192.168.0.5 is not necessary, providing the subnet mask on all devices is 255.255.255.0. So please confirm that all devices have a subnet mask of 255.255.255.0.
Also, have you tried turning off the printer off/on? Sometimes this kick in the pants is all a peripheral needs.

Jun 10, 2011 1:37 AMby Stephen Schulte2,Pahu,
THANKS- but how do I find the subnet mask for the LW? The others are 255.255.255.0 - but even on the first page printout sheet I do not see a subnet mask for the LW.
I've tried turning the LW on and off several times- that does't help.
Question: Since the 192.168.0.5 PING works and since it is not connected to anything - where is this PING going? I mean even when I UNPLUG the ethernet cable (which then goes into an adapter and then into the LW) and do the PING to 192.168.0.5 - it works! How / why I mean what is it "PINGing"?
And if the IP Address on the Printer is shown as 192.168.0.123 - why doesn't this have to change to 192.168.0.5???
This LW printer is AppleTalk and I had to set it up special to work with Snow Leopard which doesn't support AppleTalk. I was kinda planning to re-setup this printer this weekend via OS 9.2.2 - but you seem to say that that isn't needed - but again, I ask why not…
If it had never worked, I'd say OK - but it has worked for well over a year on SL---
Thanks for any suggestions, web sites or ideas.
Best regards,

Jun 10, 2011 2:22 AMby PAHU,... how do I find the subnet mask for the LW? The others are 255.255.255.0 - but even on the first page printout sheet I do not see a subnet mask for the LW.
I don't know about determining the LW subnet mask. I never had one and its been about 15 years since I repaired one. I would have thought that it would have been on that print out. But given that it was working before then I don't expect this would have changed. So if it is proving hard to determine then leave it as is.
Question: Since the 192.168.0.5 PING works and since it is not connected to anything - where is this PING going? I mean even when I UNPLUG the ethernet cable (which then goes into an adapter and then into the LW) and do the PING to 192.168.0.5 - it works! How / why I mean what is it "PINGing"?
If you unplug the Ethernet cable to the LW adapter and there is still a Ping response to .5 then there must be some other device on your network with that address. What you may be able to do is connect to the internal web page of the router (by typing its IP address as the URL into Safari) and check the address table. If all the network devices other than the printer are set to DHCP (dynamic IP address assignment) then the router will be handing out these IP addresses and have some information about the .5 address.
And if the IP Address on the Printer is shown as 192.168.0.123 - why doesn't this have to change to 192.168.0.5???
If there is another device already with the .5 network address then you don't want to set the LW to this same address. That would be an IP conflict. So it would be better setting it to .6 or even .10, especially if your router is allocating IP addresses. This would give you a bit of room if you were to get another network device.
This LW printer is AppleTalk and I had to set it up special to work with Snow Leopard which doesn't support AppleTalk. I was kinda planning to re-setup this printer this weekend via OS 9.2.2 - but you seem to say that that isn't needed - but again, I ask why not…
If it is easier to configure the device via OS9 then go ahead. I was simply suggesting that there should be no need to connect via OS 9 to get this working for the other Mac's, especially if its just an IP address that needs changing. But if you were planning on doing this anyway then fine. In fact it may prove easier to connect to the LW via the OS 9 G4 using AppleTalk and run the device setup that way or even share this connection from the G4 to the other Mac's.

Jun 10, 2011 4:15 AMby Stephen Schulte2,Pahu,
You really know your stuff!! Super!!
OK and I have not yet marked this HELPFUL because I am afraid that if I do that then I cannot also mark your comments Correct Answer later - but if I can, let me know and I'll get you a Helpful right now.
You were right about 192.168.0.5 being used: I went to Safari and had the codes to look at the status of my setup via VOO (my ISP here in Belgium - I have 2, the other a backup, but this is my main one now with 50 mbps download and 2.5 mbps upload - just great). OK so here's what I have connected:
1. "Router": (VOO Modem): 192.168.0.1
2. MacBook Pro-13" (SteveSchulteMBP13): 192.168.0.2 (wired)
3. Canon MP640 (no name given in VOO www site): 192.168.0.3 (wired)
4. eMac in Carine's room (Babette-eMac): 192.168.0.4 (wired)
5. iPod Touch (called iTouch): 192.168.0.5 (wireless)
6. PBG4 (Steve-PBG4): 192.168.0.6 (wireless)
7. MacBook Pro-13" (SteveSchulteMBP13): 192.168.0.7 (wireless) - OK I DON'T USE THIS WHEN CONNECTED VIA CABLE BUT JUST TO SHOW YOU IF I DO CONNECT BOTH AT ONCE
8. BUT NOT CONNECTED NOR SEEN: Apple LaserWriter 12/640 PS: 192.168.0.123 - no, maybe try 192.168.0.1??
OK so what happened. Well it seems yesterday the VOO company removed my VOO TV which had been connected back in March when I had the new modem installed. I didn't want the TV connected, and finally they realized this (using the Belgacom TV, yeah a bit complicated…) and so I'm just guessing that when they did that yesterday they re-set my VOO modem and it now says it assigns numbers as follows: 192.168.0.2 to 192.168.0.14 --
But it doesn't see my LaserWriter - so I'm guessing I need to go back to the G4-733, boot it in 9.2.2 and configure the LW - maybe 192.168.0.12 ???
Actually I don't know how I did that over a year ago- should have kept some text or something but doesn't seem like I did… Will I just connect the G4-733 to the VOO Modem-router instead of my MBP? (or in addition to it)?? The last thing I want to do is screw-up my otherwise fine-working system.
Thanks for any additional comments--

Jun 10, 2011 4:43 AMby PAHU,Okay, now we are getting closer. If the telco has set your subnet range from 2 to 14 then the routers IP address must be set to 255.255.255.240, which gives you 16 subnets and 14 hosts. So setting the LW to 192.168.0.12, 13 or 14 will be good. Just don't set it to 1, as you mention in point 8. This is being used by the router and will upset your network if you do this.
As for how to configure the LW, it should be fine to connect to the G4 to the router to then connect to the LW. Is this G4-733 the PBG4 (Steve-PBG4) you mention at point 6? If so then good as it already has an IP address. If not then just make sure it is set to DHCP, we don't want it getting an IP address that is already being used...

Jun 10, 2011 5:03 AMby Stephen Schulte2,Pahu,
OK but just a bit of a problem here, well question:
1. When I look at the Network Preferences for my MBP-13" (#2 above) it shows 192.168.0.2 - and the subnet mask is: 255.255.255.0 NOWHERE do I see any subnet mask for the ROUTER - WAIT you are not saying Subnet Mask, you are saying "ROUTERS IP ADDRESS MUST BE 255.255.255.240" -- so did you say that just as information, it is not something I have to change (nor maybe can change) you just sent that as info, is that it?
2. Connecting the LW: The Steve-PBG4 is running Leopard but I do not have OS 9 installed on it. Not sure if booting in OS9 is something that the Core Duo chip or 10.5.8 stopped, but the only way I can startup in 9.2.2 is via my August 2001 G4-733 which NO, is not listed above. But what I can do is start it without having the LW attached, then check its IP address, then plug in the LW (without anything else plugged-in or??) and then try to configure the IP address of the LW via the Print Utility of 9.2.2--
Does that sound like a plan?
I'll wait to hear from you before proceeding.

Steve Schulte

Jun 10, 2011 5:19 AMby PAHU,HelpfulHi Steve,
With regards to the MBP-13, its IP address is fine. What I was saying is that the routers subnet mask would most likely be 255.255.255.240, given that they have restricted your IP range from 2 to 14. And its IP address will still be 192.168.0.1.
So sorry but I was just commenting on the change that was made by the telco. There is no need to change any IP address or subnet mask of any computer on your network. Just concentrate on getting the LW set to 192.168.0.12 so that you can get printing again.
As for 2, thanks for the explanation. So yes to the plan - fire up the G4 running 9.2.2 and see if you can change the IP address of the LW using the Apple Printer Utility.
It's getting late over here so I'm off to bed soonish. See how you go and I will check back in tomorrow.

Jun 10, 2011 5:25 AMby Stephen Schulte2,OK and it may be tomorrow before I can dust-off the G4-733 to try this.
Let's see if you are in Sydney, Australia it's about 10:25 pm as I write this here at 2:25pm in Belgium.
Really appreciate this and a full report tomorrow.
Best,
Steve

Jun 10, 2011 10:51 AMby Stephen Schulte2,Pahu,
Well I took the time to boot the G4-733 in 9.2.2 and finally found Print Utility -- but what a mess. I found a note that I used 9.2.2 to set-up SL on my Mac on 24 April 2010 - but do you think I can find a copy of what I actually did?
I don't know what cables to plug-in where; tried just having the modem go to the G4 and the LW as it is set-up in SL - but the G4 doesn't see the LW - I've set Appletalk for active via Ethernet - the IP Address is 192.168.0.8 and the internet works fine (on IE 5.1 - that's going back) - but no printer is seen. Do I have to connect with other cables like parallel or ??? I need some step-by-step instructions. Really strange that I did that a year ago and it worked perfectly but that I didn't keep a single record of what I did - the 400 page LW manual isn't much help - and basically there is too much information in that manual--
Seems there is a direct UNIX / TERMINAL possible way to change the IP address (which is now hard-wired, well not wired but fixed in the LW and either I need to figure-out how to see the printer in 9.2.2 or get an OS 10.6.7 Terminal fix...)
So very discouraged and the only thing I can think of is that VOO changed the IP addresses or reset my modem so that the 192.168.0.123 isn't visible nor viable-- works great for anything newer than about 1997 so I can't really complain - but I use that printer each week for larger print jobs---
OK when time if you have any instructions, inspirations or web links I'd appreciate it.
And really appreciate all your assistance today!!

Jun 10, 2011 7:13 PMby PAHU,Good morning Steve.
Okay, found the manual for the LW 12/640 and had a look at the configuration pages and it looks pretty simple - to me
Now since we will be using AppleTalk to communicate with the LW then I feel that it should be fine to the LW connected to the router and the G4 also connected to the router. But if the LW is not appearing in the Printer Selector window of Apple Printer Utility then the router could be blocking the communication - though I am not sure why? And because of this apparent blockage then we may also not be able to use Terminal (UNIX) and the telnet function to change the IP settings. So I think the best move is to connect the LW to the 9.2.2 G4 by connecting the G4's Ethernet cable directly to the LW Ethernet transceiver (assuming you have the twisted pair receiver that allows the Ethernet cable to fit). With the cable connected between the OS 9 Mac and the LW you can now open the Apple Printer Utility and the LW should be visible. If it is then you can follow the steps, starting on page 265 Appendix A of the User Guide, to change the IP address.
I am going to fire up an old eMac today that has 10.2.2/9.2.2 in case you need extra help with this...

Jun 11, 2011 12:56 AMby Stephen Schulte2,Pahu,
OK almost 10 am here on a Sat- gotta mow the lawn but first here's some feedback here:
1. Yesterday when the Apple Print Utility 2.2 did not see the Printer going via the modem, I did connect the ethernet cable (just the standard cat 5 UTP cable that I've been using for several years with this LW printer and then that adapter at the LW end) directly to the G4-733 and the LW. Still nothing.
2. OK I found the same manual as you must be using with Appendix A and the section on changing the IP address on page 265.
3. Again, I did this on 24 April 2010 - but yesterday I could not communicate with the LW printer.
So in the next few hours I will try to get back to this. Is there any other way to connect the G4-733 to the printer so that Apple Print Utility will see it? It must have gone so easily last year that I didn't take any special notes, just followed the manual - but the IP address was of course factory set at 0.0.0.0 at that time; and now it is at 192.168.0.123 -- is that somehow causing the problem? I do have another modem (my "Skynet" ISP) but I'd have to lug the printer upstairs - don't see why that might be different. And I guess I could take my DIR-635 router and connect it to the VOO Modem-Router and then plug the LW into that, but again, why is that going to help?
Thanks for any help and especially if you have any luck with your eMac with 9.2.2.
Best regards,
Steve Schulte
