How can I scan a barcode for a print file and have it automatically print? -

I have 300 t-shirt designs in a folder saved as print files for my printer. I have created barcodes for each design and put them in a 3 ring binder. Now when a customer asks me for a certain design how can I scan the barcode and have my PC automaticly send the file to my printer without having to use my mouse or keyboard. Is there software out there to do this? Thank you

Try with Xerox FLOWPORT. Or inquire with them. They have software of this kind.
