If I understand it right, you want to transfer the file from one computer to the other from which you could print. As far as I know, the quality of the memory stick is not going to affect the quality of the photograph. Any simple memory stick will do.
Canon EOS 1100D, 18-55mm III, 50mm f/1.8 II, Canon 80-200mm
If I understand it right, you want to transfer the file from one computer to a printer or to a print shop. The quality of the memory stick is won't to affect the quality of the photograph. Any memory stick will be ok.
And if the file is too large to email, use TransferBigFiles.com
You can send up to 100 MB files with a free account. I use this at work almost every day to send large files to clients, commercial printers, etc.
The beauty of TransferBigFiles is that the person that receives the emailed link doesn't need to have an account with TransferBigFiles. They simply click the link, then click the download link. Totally rocks for moving big files!!
