Of course there must be a reason.

Only a guess:
Perhaps the printer is waiting for some kind of "end of job"
signal (e.g. a formfeed character or a printer reset sequence)
after printing via the "raw" queue.

What I have in mind:
The printer receives the raw print job but at the end the
"end of job" signal is missing.
In this case the printer may eject the last sheet after a
particular timeout (e.g. after 10 seconds waiting) but
nevertheless the job is not yet finished for the printer
and for a subsequent job the "Printer is not ready".
I.e. the raw print job may be in fact incomplete and therefore
you cannot use a "raw" queue to print such jobs.
You may test if it works to add a "System V style interface script"
for the "raw" queues which sends such an "end of job" signal
at the end of the job (then those queues are no longer "raw").
