A couple I know have two computers I'm supporting – one is a iMac which I recently upgraded from Snow Leopard (10.6) to Yosemite (10.10). The printer is attached to this machine. The other computer, unfortunately, is a 450MHz Power Mac G4 (AGP graphics) running the last version of Panther (10.3.9). Surprisingly, the 14-year-old computer still works and is actively being used (primarily for AppleWorks documents, which is another "ugh").
Before the iMac was upgraded, I had done something to it which let the Power Mac see the shared printer. I suspect it had to do with CUPS, but I could be wrong. Ever since the upgrade to Yosemite, the Power Mac has been unable to print, and I can't seem to recreate the old setup.
My question resumed in one sentence is:
How do I share a printer from a Mac running Yosemite to one running Panther, so that the Panther one can print?
Best Answer
For clarity I will name your Power Mac G4 running Panther:
Pant
and your iMac running Yosemite:Yose
.Yosemite
has problem to print in an IPv4 environment (see: How to make shared printing works on Yosemite within an IPv4 only network?. On the other handPanther
is able to runIPv6
.Check IPv6
Hence the 1rst point to check to be able to print from
Pant
is that Ipv6 is up and running. IfPant
andYose
are connected through Ethernet, you will check this with (this is a command to enter withinTerminal
):and you should get an output containing a line starting as:
Which prooves that
Pant
has an IPv6 address and is IPv6 connected. If they are connected through AirPort, you have to check the same output with:If
Pant
doesn't have an IPv6 address, you will have to modify its network configuration through:select
Advanced...
and under theTCP/IP
window, selectClick OK, Apply. Check that IPv6 is now up and running.
Check cupsd
If you just enabled IPv6 for the 1st time on
Pant
then you will have to restartcupsd
so that it will be able to talk this protocol.The easiest way is to simply restart
Pant
. (But if you prefer to understand what you modify clearly, to restartcupsd
is sufficient).You will now have to check that
cupsd
is able to talk IPv6. (If I would had a Panther running Mac at hand I would have answered directly, but I don't).Here are the command to type within
Terminal
to perform this checking:will display you 2 lines as:
where the number
PID
is the proces id of thecupsd
daemon.Use this process id (here 76864) to check if this daemon is talking IPv6 through the help of
lsof
as follows:This is a priviledged command, hence you have to use
sudo
which will ask you your user password. This command should give you an output very similar to:If you have a line where
TYPE
==IPv6
then thecupsd
onPant
is talking IPv6.Restart the sharing
If you just enabled IPv6 for the 1st time on
Pant
then you will have to enable from fresh the sharing onYose
so thatPant
will see it correctly through the IPv6 channel.On
Yose
openstop
Printer Sharing
, wait forPrinter Sharing: Off
to display, and restart it.On
Pant
add a new printer, and you should see a new one to add and configure onYose
.Disclaimer
This is a blind receipe (I don't have a Panther to fully check it). I tried to avoid at most dangerous modifications on MacOS.
Any feedback would be appreciated to improve this draft answer.
