Hi,

I have attached the below patch in an attempt to fix this. I notice that
printing.el requires lpr.el, and pr-switches function anyways uses
lpr-flatten-list from lpr.el. So there should be no harm using
lpr-eval-switch instead of ps-eval-switch. I have verified that
lpr-eval-switch is the exact same function as the now obsolete
ps-eval-switch; just different names.

Copying Stefan for reviewing and commiting this patch as he was the author
of the commit

where
ps-eval-switch was removed.

Subject: [PATCH] Fix reference to obsolete fn ps-eval-switch

The `lpr-eval-switch' is functionally the same as `ps-eval-switch' which
was obsoleted in 2cdeb903c57126d3ad5f0cbd72e182584b76ee29.  So using
that instead (Bug#19717).

* printing.el (pr-switches): Use lpr-eval-switch instead of ps-eval-switch.
