Hi Carolyn and welcome to the forum.
Michele and Rick gave you great info... I can only add that you can cut your ink costs after you buy your printer by buying 3rd party inks, either re-fill carts or bulk ink systems. There are suppliers like inkjetcart.us, shopdyesub.com, and inkjetfly. There are more, but these names I see quite frequently on the forum.
If you choose JetproSofstretch paper, the price can vary greatly. Some additional suppliers that have excellent pricing are tshirtsupplies.com and New Milford Paper. Sign up with all the suppliers for their newsletter, so when they run a sale, you'll be the first to know. It's nice to never pay full price.
I use Ironall Dark as well. I like it bc it is stretchy, but some folks don't like the textured surface. I buy it at New Milford. There is a second paper that folks on the forum really like, it is called JetWear, that is at tshirtsupplies.com and it is the same paper that people like that is called Alpha Gold for Darks, which is from Alpha Supply.
Accessories you might want to add to your heat press supplies are a teflon sheet to keep your upper platen clean, a fitted teflon pad to keep your lower platen clean. A mess on your upper or lower platen can be a bear to clean off. These sheets make clean up a breeze. Parchment paper can be substituted for teflon on the top. If you do get a big mess, EZ Off is a cleaner for the upper platen. It's not the EZ off for Ovens in your home, it is different, and made for platens.
A lint roller. I won't press without mine. I use the sticky tape kind because it grabs those little loose fibers, and then I peel it and throw it away. Those pesky fibers show up after I press... they glare at me post press, haha, when I couldn't even see them before I pressed.
If your press doesn't have a built in timer, a stand alone timer is great. It beats watching and counting the seconds on the clock.
Some mouse pads to raise the material above the seams when pressing. I happened to have mouse pads here that worked. I just cut them to size with a scissor. They are awesome. Uncorrogated cardboard does the same job.
For lining up the transfers... I spent $11 on a June Taylor Fringe Cut. It was from Walmart. It's clear, lined and numbered. Some others here use this too. It's a big rectangle, and very sturdy.
Store your transfer paper stock in the plastic bags it comes in, or your own, but keep them in plastic as they can be finicky about the humidity in the environment.
Lastly, for you, I have a post about how to press step by step instructions, the how and whys included. Good luck to you and your husband, hope you enjoy this process:
