Yes.  Which means hpiod and hpssd will want complete, total, unshared
control of the connection to the MFP device while scanning or printing.  It
does not care what happens to the connection during idle time (it closes and
reopens the connection every time it processes a job, be it a scan,
photocard access, fax or print job).

I have recently removed the hpoj/hplip conflict from hplip in sid.
Unfortunately, sarge retains the conflict.

IF the hplip packages are manually fixed to kill the conflicts header, yes.
sorry about that.  I will remove that header from backports, which should
come soon to the hpijs alioth project.

Correct.  hplip does not work with parallel connections.  It could, but HP
upstream won't write the code, and nobody seems to be willing to improve
hpiod to do so.
