You *might* find something on Windows Update.
I'm still using an OLD OLD Epson 1290 photo printer - Windows update even gave me a 64 bit driver for this one --- Epson's last drivers for this model were Windows 2000
- but I like the printer because I can still print at A3+ size.
Try and see if Windows update finds a driver.
Otherwise another solution is to load up a tiny Virtual windows XP machine (don't install any apps on it) and just use it to share the printer with your Windows 7 machine.
You can download VMWARE server for free -- this IMO is a better option for this application as the VM can be started in the background (and automatically on boot). You just then install the printer on the vm and then share it.
On the Windows 7 machine -- as you don't have a driver for it you''ll have to define the printer as a NETWORK printer.
Then define this as your default printer.
