Samba operates on a single thread model, per client. The client decides
how many connectons to make, and windows always uses just one.
As such, all other operations on that connection *will* block while we
print - particulary if the remote print server blocks.
It may be possible to 'background' the print process (by twiddleing the
print command) but I don't know what implications that might have.
