I realy did not think there was a difference between a pressure cooker and a pressure canner other than size. The key is that the correct pressure and thereby temperature is achieved for sufficient time.
Myself I don't think I would risk canning low acid foods like meats and veggies other than tomatoes without using sufficient nitrite/nitrate, salt or acid to prevent botulisum spores from germinating. Issue is that there is not always 100.000% of the time enough heat in the process to ensure that all botulisum spores are destroyed. Packing meat in quart jars for canning is also a no-no as it is difficult to ensure the center of the jar is brought to full temperature.
The health risks of canning or curing meats are significant, really worth becoming well informed before jumping in both feet. There are a number of good books.
