Maybe I'm misunderstanding.....don't you have to install the desktop version in order to print to a printer connected to that desktop? That's what I did, then I installed the free phone version on the eDGe. Then sent a print job from the eDGe to my shared printer. After it printed, it shows in the printer share manager on the desktop as having 19 pages left. Next to that is a link to "Buy More" pages.
Are you saying that if I just sent print jobs from my eDGe to this printer it will let me go past the 20 page limit? I guess I'll soon find out.....
