Plenty of older business systems still produce plain text. ERPs, accounting and order-processing packages, stock and warehouse systems, anything that prints fixed-width reports or spools to a line printer. The invoices, statements and delivery notes they generate come out as flat text with no styling.
This tool turns that text into a tidy, branded PDF. Really though, it's here to help you find the right settings. Load a sample of your output, adjust the options until the preview looks right, then take those settings away and use them in your own setup. The rendering itself runs on the API. This page is just where you work out the configuration.
Lines/page (how long a page is in your source), Skip each page (removes a
header line that repeats at the top of every page) and Encoding (use cp850
for old box-drawing characters).Your files aren't stored. They're only sent across to build the preview. A proper write-up is on its way to the blog.
