In Unix/Linux/Posix, time is counted in "seconds since the epoch" and is
timezone-agnostic.  The timezone is only used when converting to/from
this number of seconds from/to the usual "year/month/day/hour/minutes/...".

"The printer" is probably not 4 hours behind anything.  Presumably it's
just some part of the printer's software which chooses to use PST when
*displaying* time information.

It's serving *the* time :-)
