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 hand Panther
is able to run IPv6
.
Check IPv6
Hence the 1rst point to check to be able to print from Pant
is that Ipv6 is up and running. If Pant
and Yose
are connected through Ethernet, you will check this with (this is a command to enter within Terminal
):
ifconfig en0
and you should get an output containing a line starting as:
inet6 fe80::
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:
ifconfig en1
If Pant
doesn't have an IPv6 address, you will have to modify its network configuration through:
System Preferences > Network
select Advanced...
and under the TCP/IP
window, select
Configure IPv6: Automatically
Click 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 restart cupsd
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 restart cupsd
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:
ps ax | egrep '[ /](PID|cupsd)'
will display you 2 lines as:
PID TT STAT TIME COMMAND
76864 ?? Ss 0:00.26 /usr/sbin/cupsd -l
where the number PID
is the proces id of the cupsd
daemon.
Use this process id (here 76864) to check if this daemon is talking IPv6 through the help of lsof
as follows:
/usr/bin/sudo lsof -p 76864 | egrep '(COMMAND|IPv)'
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:
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
cupsd 76864 root 9u IPv4 0x9007abdfc3bf58ad 0t0 TCP localhost:ipp (LISTEN)
cupsd 76864 root 15u IPv6 0x9007abdfb88bf0cd 0t0 TCP localhost:ipp (LISTEN)
If you have a line where TYPE
== IPv6
then the cupsd
on Pant
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 on Yose
so that Pant
will see it correctly through the IPv6 channel.
On Yose
open
System Preferences > Sharing
stop Printer Sharing
, wait for Printer Sharing: Off
to display, and restart it.
On Pant
add a new printer, and you should see a new one to add and configure on Yose
.
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.
