We are very happy to have a printer on board. Several countries we've visited want you to download, fill out, and print a PDF form (or two or three) before you arrive. It also seems like we never have enough copies of our documentation
and crew list, and constantly print those.
We have a Dell color laser. Which is a problem -- no where we've been from the Caribbean
has Dell cartridges. And we've looked all over, even in 'big' places like Panama
City and Papeete. HP, Canon, Brother, and Epson cartridges seem more readily available.
For electronic chart backups, I'd look at inexpensive paper copies from folks like Bellingham Chart Printers, or adding Navionics
(or etc) to an iPad
to a second laptop
