Can I Share a Printer Between OS X 10.3.9 and 10.5.2?

Question

I posted this question under Mac OS X v10.5, but since I did not get a response so far, I hope this category is more appropriate.
I would appreciate detailed guidance on how to set up printer sharing for two older Macs - assuming that this is even possible in this case. I have the following Macs that work very well independently as well as through a router for internet access.
1. MacMini, 1.5 GHz, Bluetooth+Airport Extreme (approx. 3 yrs old) running OS X 10.5.2 and using Airport for internet access.
2. Power Mac G4, 466 MHz (approx. 7 yrs old) running OS X 10.3.9 and connected directly to the router for internet access.
An HP Deskjet 5940 printer was used exclusively with the MacMini, and a Lexmarl Z53 was used exclusively with the G4. The Z53 just reached the end of its life, and thus I disconnected the 5940 from the MacMini and connected it to the G4 where it now works fine.
In spite of all attempts with various settings at each Mac, I have not been able to get any printing done from the MacMini. What detailed settings/connections do I need to make so that I can use that 5940 printer from the MacMini?
Thanks for your response.

OK, now go to System Preferences > Print & Fax, There, select the Printer you want to Share and lower down Check the box 'Share my Printer with other Computers'. This you do in the G4.
In the Mini, Turn on WiFi, and see if you can see it. If not (mine did not show up the first time), go to Print and Fax and 'Set up new...'. Yours may still be trying to find the one that you put in the device for with solid wire... but that is not the Bonjour one (yes it is, but the computer does not find it because it is not connected exactly as you first installed it). In fact, you do not need the device driver installed on the Mini for this printer, as the G4 has all that and you are using the G4 as a Host (server) for that printer. In Set Up, go for a new printer, and let it locate the Bonjour one, once it does, Lock It In! You have it... also, you do not need Print Sharing ON in the Mini, Just the G4 (Host).
When you go to Print, a list (selection box) shows up, click it, the Bonjour Printer should be at the bottom of the list, with a side selection once you click it... slide over to the Printer Name and click, it will come up into the selection box and you can then Print. It may take a few seconds to lock in with the so called 'hand-shake' ("are you there? yes I am! can I print to you? yes you may! ok, here it comes...") Or Computer-Printer talk like that.
Now, something I did not have to do with my older Printer, but did have to with my newer one, is make 'AppleTalk' Active. It has something to do with printing, or whatever, (can't find much info on it). You will find it in System Preferences > Network > there, 'Location'= Automatic; 'Show' = Airport; 'AppleTalk' = CHECK; 'Configure' = Automatically. It depends on the vintage of the printer and whether this is needed or not. My 1600 didn't, my 2500 does. Don't ask me about this, it is just something I found while searching for answers one day, that had to do with printing... this, after I could not get my New Printer working Like I had my Old one working... that is what made it FLY!!! And yes, my daughter brings her computer over here and uses my High-Speed internet, and also my Printer... she does not have my printer device on hers, we do it all thru WiFi JUMP from my 10.3.9 computer to her 10.4.11 computer. (Your 10.5.2, I am not familiar with, but it should work like-wise)
Good Luck
