I haven't yet tried Wolfgang's program so I may be totally out of sync and making no sense here, but I'll contribute this:
In the absence of a 'device driver' solution... Assuming it's a filter program which for example copies the file printed to ram1_ to a chosen printer... 1. Reserved filename, say "ram1_prtfile_dat" or similar. (Would allow printer drivers to be configured to this filename if this is the only printing method available) 2. A job runs which checks for a new file of this name (check for file existing of that name and it's last known date printed). 3. When filename exists with a date which hasn't been printed before, print it. Make sure that the job which sends it to the filter keeps it open or some means of preventing the file being changed (i.e. "in use") until it's all been sent to the printer. Contention avoided. Finally, as I haven't been using your program, Wolfgang, does it require the full Prowess (which I don't use) or just Proforma?
