Google CVT2CMD – it is a fairly simple command and program that will generate a PDF from a spooled file. I’m pretty sure it is not limited to a 132 column spooledfile. The PDF is generated to an IFS directory – from there you can FTP the file. There are lots of references on the web to setting up an FTP process.
You might also investigate a product from Gumbo in Seattle called “Spool Convert” (command SPLCONVERT). I have used it with print files larger than 132 (up to 198 in my case), and it does a great job with overlays, and can create PDF (and others, although I have not used anything but the PDF). Ours were placed in the IFS and then used FTP to send elsewhere. Good product, and very inexpensive for the power.
