Printer Comptability with OS X

[Happs]

I will be buying a new Mac soon with OS X (Leopard) on it.

We have two Windows XP PC's in our house that have desket (inkjet) printers attached to them. One is an Epson Stylus 600 that says Windows/Macintosh compatible, according to the owners manual in 1997. The next one is an HP 960cse from the year 2001 that is Windows only (installation cd that came with it is for Windows only). The Epson uses thea popular S020093 and S020089 ink cartridges and the HP uses the popular HP 45 and 78 ink cartridges. I have a plethora of extra ink cartridges on hand for both printers that I was able to acquire extremely cheaply and was wondering if these two printers will work with OS X (Leopard)--or if not how to find out which ones that take these cartrdiges will work? In addition, the Epson does not have a usb port, but rather a parallel port (which I currently use) and a serial port.

I noticed that the Mac Mini and iMac do not have parallel ports, so can a parallel to usb port adaptor be used?

Thanks.

P.S Is it best to keep an old printer going for as long as you can or to buy a new one because they are supposedly new and improved?

you can, or you can just get the free printer that they offer on new Macs after rebate...just do it
