Thanks so much for taking the time to reply. I do appreciate it!
Currently I'm using PDFCreator only to convert a tiff file to a pdf file. Technically that's might be "printing", but I'm not sure. The total process is once I have the tiff file open as a pdf, save it, Once saved I then reference it into a CAD file.
The process usually takes a couple of minutes until I ran into the 751Mb file. At the time it seemed nothing was happening which led me to think I hit a wall as to what PDFCreator (especially when using the free version) was capable of handling.
This morning I noticed when opening the tiff file with Windows Photo Viewer, the current file (which is 879Mb) took a few mintues to open. That led me to try opening it with PDFCreator, and pulling up Task Manager to have a glance at what might be running.
I can't past a screen shot (I think), but PDR Architect 7 is running in the background and processing something. The stats say it's 9.9% CPU, and 979.1 MB (and counting) in Memory.
I'm being patient ad watching what happens.
I'll keep you posted. Thanks again for you help!
