If you get a hangup when printing from <anything> directly to Distiller (or Distiller Assistant), then do it in two steps.
First, set up a dummy ps printer in Windows, which will "print to file". It can be an Apple color laserprinter, or something like that. You don't need to have the printer, This is just a set of parameters to use when the print file is created.
1. Print from Mathcad to this dummy printer, which creates a file on disk. This will be a print file in the postscript language format.
2. Start Distiller, and use it to open the print file and create a PDF file. You can mess with job options for font embedding, etc, as much as you need. (tweak settings, distill file. check file, repeat as needed.) When you get it right, save the job options for future use.
You may need to tell distiller where the fonts are that Mathcad is using.
Anyway- this prevents hangups when printing, and allows quicker experimentation with job options, etc.
Good luck!
