Printer to crawl and print on drawing

Were to get this printer.?
We are an engineering company that reviews drawings from customers and must either print the feedback commnets on the 4-20 foot drawings or print a symbol of approval. We’d also link to print barcodes as well. SO we need a printer we cans set in the middle of the drawing and either have it pull the drawing under it while one holds it, or a printer that crawls across the drawing printing as it goes. Any ideas or sources?
