Would you tell us exactly which iMac model you have? Open System Profiler in the Utilities folder and report here what is displayed for the Model Identifier.

OK. You can upgrade all the way to Mountain Lion if you wish. But you will need to upgrade RAM once you get to Snow Leopard - 10.6.x and above. Here's the requirements:
Snow Leopard General requirements
- Mac computer with an Intel processor
- 1GB of memory
- 5GB of available disk space
- DVD drive for installation
- Some features require a compatible Internet service provider; fees may apply.
- Some features require Apple’s MobileMe service; fees and terms apply.
Lion System Requirements
- Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
- 2GB of memory
- OS X v10.6.6 or later (v10.6.8 recommended)
- 7GB of available space
- Some features require an Apple ID; terms apply.
Macs that can be upgraded to OS X Mountain Lion
- iMac (Mid 2007 or newer)
- MacBook (Late 2008 Aluminum, or Early 2009 or newer)
- MacBook Pro (Mid/Late 2007 or newer)
- MacBook Air (Late 2008 or newer)
- Mac mini (Early 2009 or newer)
- Mac Pro (Early 2008 or newer)
- Xserve (Early 2009)
Are my applications compatible?
You can upgrade your RAM:
Maximum Memory 6.0 GB (Actual) 4.0 GB (Apple) Memory Slots 2 - 200-pin PC2-5300 (667MHz) DDR2 SO-DIMMs
I would recommend upgrading to the maximum your computer supports.

I don't really need to upgrade all the way. I just need to upgrade it to 10.5 so that I can use the newer printer. But where could I find a 10.5 OS?

Phone the Apple Store and order a Mac OS X 10.6 DVD. At this point, it's generally not worth bothering with Mac OS X 10.5 when upgrading an Intel Mac's OS.

A long time Mac user told me it is not possible to upgrade directly to 10.6 from 10.4. Is it true?

Essentially it's far better to do a clean install of Snow Leopard than to attempt to upgrade a Tiger installation. Less chance of problems. Backup your Tiger system, boot from the Snow Leopard DVD, erase the drive, then install Snow Leopard. You can then restore files from your backup.

Thank you Niel and Kappy! I think this is the only clean and good way to solve the problem. And it is much cheaper.
