It seems it was searching for a program called "" (the empty
string).  Weird.

This backtrace appears to be a bit short.  As you can see, it invoked
print-region-1.  C-h f tells you it's defined in lpr.  So do M-x
load-library RET lpr.el RET (the .el part is important) and retry.  I
think this gives you a better backtrace.

Have a look in the source: M-x find-function RET print-region-1 RET.
Then search for "process".  This finds the following statement:

(apply 'call-process-region (car new-coords) (cdr new-coords)
                     lpr-page-header-program t t nil
                     (nconc (list "-h" title)
                            lpr-page-header-switches))

As you can see, it invokes lpr-page-header-program.  I'm guessing the
value of this variable is "", the empty string.
