This is a bit of a specialist topic, and only peripherally connected to photography, but does anyone on here know how to generate a bar code from a given number?
I have been given an ISBN (International Standard Book Number) for a book of photographs and poems of mine that I am self-publishing, and I need to print it as a bar code on the back cover.
Any idea on how to do it simply and cheaply without going to a specialist agency or buying software that I'm only ever going to use once.
Thanks
