found_fontname = False
font_search = '/FontName /ACaslonPro-Semibold'
type_search = '/FSType 8'
for line in file('foo.txt'):
	if font_search in line:
		found_fontname = True
	if found_fontname and type_search in line:
		print 'doing something with %s' % line
		# reset to look for font_search
		found_fontname = False


or, you could

sed -n '/\/FontName \/ACaslonPro-Semibold/,/\/FSType 8/{/\/FSType 
8/p}'

You omit what you want to do with the results when you find 
them...or what should happen when they both appear on the same 
line (though you hint that they're a couple lines apart, you 
don't define this as a "this is always the case" sort of scenario)
