Please explain how the printers would be accounted for under GAAP based on the following intended usages including the initial journal entry and at the point of sale or end of service life. If treated as an asset assume no residual value.

$1.$ One will be used as a demo on the floor for two months and then sold for $$6,000$

$3.$ One will be used by the accounting department for $4$ years.

$4.$ The rest will be sold for $8,000$ each.
