If I print the boarding card - I use the laser and take care not to fold the paper in the sensible way.
That is, the problem is with the layout of information on home printed passes prevents you from folding it in the sensible way. The information is so badly laid out that you cannot fold the A4 page twice (presenting a neat size not much bigger than an ATB ticket) that fits into a pocket or bag. IF you do fold it twice - you fold it across the large square bar code.
If you fold it where they print dotted lines, the page is then too large to fit neatly into a pocket. Accordingly, I tend to get the pass from the machine at the slow bag drop.
How the airlines could manage to layout the information (text and images) in such a poor way is a mystery ... actually, No. I can well imagine that a committee could louse up this important document and make it more difficult to use.
