That really depends on the backend.

For socket:// and lpd:// devices, in most cases the connection will
either be refused or the job will be aborted while we send it.  For
a connection-refused situation, we retry indefinitely unless the job
was queued on a class (in which case the backend aborts and cupsd
tries the job on the next printer in the class...)  For errors that
occur while we send the job, we abort and stop the queue (this
behavior is configurable in CUPS 1.2...)

For ipp:// devices, we can retry indefinitely unless we get some
sort of fatal error (like "printer doesn't exist").
