I get this same problem. My solution is just to turn google drive off while I'm working and then just let it sync at the end of the day. Google drive won't let you save whilst it syncs the file. Dropbox does appear to let you sync though and has a lot less problem. So you could switch over.

@unknownuser said: Thankfully my printer has it down now, so I just send over the files and order at will. They are really good at making adjustments and testing before final printing. Look after that one mate! My printer hands me stuff with huge lines across it smiles and hands me the bill!

Thanks, Santiago. I'll use this from now on.
