Looking to add company logo before printing on Shinko Dye-Sub

[kelifornia]

Hi All,

This is my first, so apologies if I demonstrate any poor forum etiquette.

My company is doing a side job for a charitable function and will be shooting Santa photos on-site at a weekend-long event this December.

We are using a Canon Rebel T2i and printing on a Shinko Dye-Sub. We were hoping to eliminate the laptop connection and just use pictbridge, but our partner company is looking to have their company logo on the bottom corner of each photo (as they are giving these photos for free!0

Can anyone suggest the easiest way to do this? I think editing each photo in Photoshop before printing will be too time consuming as we expect a lot of foot traffic.

Thanks in advance!
