For print in one page TT with short time periods we need to change td_height and make it little. Perhaps fet can write for default a value depending on the number of periods in a day user deffined.

Another nice thing will be write a CSS preferences dialog, but I suppose it's harder.

PS: Write this css file and use html for output were a very good idea.

Yes, I knew this.

I told about FET writing this value depending on the # of slots.

This is the only value I have to modify each time I want to print a timetable. Just 20 seconds..
