I think a universal driver was mentioned here which may enable me to print from the MacBook, via wi-fi, to my old, out-of-date Epson printer. Can anyone jog my memory?
I assume the printer is wi-fi enabled? If that's the case, I'm surprised they don't have an up-to-date driver for it. However, if it sin't or they don't and your iMac can print to it, you could always get the iMac to "share this printer on the network". The MacBook would see it as the "Epson on the iMac" and the iMac would need to be switched on and awake for it to work.
