I use my PowerBook primarily for my business (law). When I send a fax, I always want a copy of what was faxed, including the cover page and transmission information. In fact, I am so used to having a copy available from GlobalFax in OS 9 and FAXstf in OS X, I never thought of the possibility that fax software would not keep a record of what was sent. Unfortunately, that is the case when faxing from the Print Dialog in Panther.
I recently faxed a document (thankfully, not business-related) from the print dialog. When I looked for the copy I expected, it was nowhere to be found. After a long conversation with Apple's support people (escalated to a "Product Specialist"), I was told that the best I could expect to find as a record was a log entry. After dutifully opening the Console and accessing the Logs, I found the fax log under /var/logs. Unfortunately, the log was empty.
I've now learned my lesson: I'll never fax from the Print Dialog again. It is a great feature and worked well, but at least for me, it is worthless without a record of what was sent and when.
