Try CutePDF – It’s free.
With the download you set up a printer on your pc, which isn’t in fact a printer but creates a pdf wherever you point it when prompted. On the AS400, you need to set up a printer session which points to this ‘printer’ and change your spool to go to it. Then release the spool (‘6’) and, if it goes to *MSGW status, enter a ‘7’ and ‘i’ to ignore, after which you’ll be prompted for where to place the pdf – it always remembers where you stored the last one you did, handy if always using the same location on your pc/network.
It is good, hope this helps.
