I have not experienced any broken chains.  With generic (Debian
Wheezy) driver my Samsung 1640 printer would not print any pages
randomly.  cups administration (localhost:631) would show things are
fine.   At times a cups restart would help.

I don't think so.  My problem with Samsung 1640, were on Debian.

Yes, it would work for a while for me.

In my case, I installed the printer driver for 1640 from Samsung's
support site and things have more stable for me.
