Yes, It would also be easier to send to rs232 for recording so you
could use a 8 pin chip. There is some PIC timing info. in archives.
Another method is to download this software at 
http://www.comnet.ca/~logixell/Demo.htm 
and connect to your printer port, this is a free working 1 channel
logic analyzer, tells you which wire to cut in your printer cable,
so you can use it now.  It is DOS based, I downloaded it last
year but have never had time to hook it up, I use my PIC's for
any timing stuff.
I would suggest a interface circuit, I'm sure there some nasty 
+ and - spikes.
