Please fill me in if I'm wrong but unless I'm mistaken,, ExpressPCB is a paid service that prints your PCB but I don't think you can use it to print your own PCB.
Ahhh, yes... Sorry, I have been doing this for so long,
I forget that others may not have been doing what I sometimes take for granted
ExpressPCB is a free download. Not a free board service.
True, ExpressPCB has that paid board thing built in, but I don't use it.
It will however, allow you to print out the PCB artwork you create in the program.
I use ExpressPCB to create the PCB artwork, then print from the program onto transfer paper.
Then iron the transfer onto the blank board.
Then etch it myself with ferric chloride.
There are plenty of tutorials online that go into detail of the process.
Once again, Google is your friend.
It's a new day and I re-read what I wrote above....
I made some changes to what I originally wrote.
