I like my ipad 2 verizon
but trying to figure out how to make it do a few things.
airprint, and also want to do some invoicing (template)
I can just fill in while on the go.
You might want to start by reviewing iWork Numbers HERE - basically part of a trio of Apple office apps (others are Pages & Keynote, both of which I own).
I've not used Numbers but there are templates shown in the link, one related to invoicing - not sure 'how detailed' your needs may be and I'm sure others can recommend more options to you - good luck in your selection(s).
Good to hear from you. You’ll find a whole bunch of iPad enthusiasts in this Forum who are only too willing to help other iPad owners and to hear of their experiences. Don’t be afraid to post any questions you may have or use the ‘Search’ button near the top of the Forum web page. I usually find I discover one new interesting and useful piece of information about my iPad every day - and often not even what I was looking for!!
Hope to hear from you soon with your thoughts about the iPad.
Have fun and enjoy your iPad
