Fida-

>I would like to do some mirror printing on a HP 1100 laser printer. The problem is that HP drivers don;t allow mirror printing for the laserjets. Does anyone have a driver for the HP 1100 or a utility or class or something that will allow me to achieve this. But it must be a only for a HP 1100.

Use at your own risk any custom drivers you find there. Also, you used to be able to "commission" drivers, too. I have _no_ idea about legality of that.
