supported travel printer and scanner

[Jacob Yocom-Piatt]

i am looking for a travel printer and scanner (two separate devices) 
that are supported by openbsd, specifically amd64. i am aware that this 
info is listed on the site but a suggestion from an actual user is what 
i'm after prior to purchasing.

main things i'm after are
- durability
- reliability
- compact and low weight

any extra information about which software you use to get the devices 
working would be great.

cheers,
jake
