Pentax pocketJet 3?

Printers require printer drivers. If there is no compatible printer driver, then it's likely the printer will not work. If there is only a PPC driver for the printer then it is not going to work. You will need to contact the manufacturer to see if a compatible driver is available or will become available. However, we are discovering gradually that many printer manufacturers are not going to upgrade drivers for their older and obsolete products.

As for the tablet you will want to contact MacAlly about that. Most tablets require a proprietary driver, and it must be one that will work with SL and on an Intel Mac.

If you need these items for daily use then I would hold up on using SL until you find suitable substitutes or the manufacturers release compatible drivers.

If your older driver is PPC only: It will Not work in 10.6, even with Rossetta.

After that, yes, it should "work". But possible not well with 64-bit applications (You won't be able to set printing options): Mail, Safari, Preview, etc.

You can definitely print with a PocketJet under Snow Leopard.

I added a Pentax PocketJet3+BT to my MacBook after converting to Snow Leopard. Printer was an auction buy from a photo dealer with no accessories or documentation but an exceptional deal. Got the rest of the items I needed today in the mail from another photo dealer(battery pack, charger, instructions, cleaning paper, etc.).

Installed the Pentax .dmg file. Not perfect, but it definitely works. Can get it to work by USB cable with the driver on the printer default settings. Haven't got the Pentax printer utility or the wireless or infrared hookups to work yet...not that critical because I just need this for quick prints on the go with little weight and don't want to bother with complicated software or settings. Just want to turn it on, plug it in to the USB port and hit command-P to print a web page or document. May tinker with it another time to see if I can get other bells and whistles to work...

In "mac hd/activity monitor/utilities/activity monitor" you can see what kind of active item is being used under "kind". It says 64 bit intel for full fledged snow leopard apps, just intel for I think 32 bit apps, and PowerPC for dated stuff. Some dated PowerPC stuff will run including my dated Canon scanner with all the driver software.

This is the link for drivers for Snow Leopard and Leopard OS X for use with Pentax Pocketjet 3. I tried it in both versions and works fine with no issues.

If it's a PPC driver it will not work on an Intel computer. If it's an Intel driver for OS X and it works with Leopard it may work with Snow - no guarantees that it will.
