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 to
Fiji 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 or
OpenCPN to a second
laptop.
