The software is very simple to use if you know how it works in general! There are many different choices for what type of printing order they want (for example only color or black/white), but there isn't an option where I could just tell them "do whatever" without any instructions from myself as far my knowledge goes - so this takes some time getting used too.
And while we're at ordering papers with images etc., now when someone wants us make copies after finishing our work together over eMail instead having another meeting about everything again which was sometimes also quite cumbersome since those meetings were held outside working hours by default; well all other things aside these two problems solved themselves once one got familiarized enough :).
