dopdf doesn't work for me at all:
Trying to produce a pdf from a file listing (list of tiffs), I right-clicked on a filename, selected print, either used default save file name or change it, select small file and open pdf in reader. The progress bar shows completion, the dialog box closes. There is no pdf file saved anywhere.
Trying to produce a pdf from Excel, I clicked on file/print, selected dopdf as the printer, made selections as above, click OK. The dialog box disappears along with the Excel message that it is printing, and nothing happens.
I've tried this with Comodo (firewall) disabled, but there is no difference.
I've used CutePDF writer with no problem and will just go back to that, but I was looking for a solution that produces smaller-sized pdf files.
