There are two buttons in the Easy Customization that change
the value of a user option: ‘Apply’ and ‘Apply and Save’
If you click on the ‘Apply’ button, then it will set the
value for the current session, only.  If you click on the
‘Apply and Save’, then it will write the expression to your
initialization file (which it is possible to specify).

Your customization file can be your init.el file or it can
be another file.  See (info "(emacs) Saving Customizations").
For simplicity, unless you change it, it will be your
initialization file.

The value that you choose here should be one of the values
that you set in ‘prt-txt-printer-alist’.  If you have only
one printer, specified in the association list as ‘default’,
then this value would be ‘default’ instead of ‘prt_06a’:

  (setopt pr-txt-name      'default)

Note that because this value is the default that Emacs sets,
you do not have to include this expression at all.  Simply
confirm that the value is ‘default’ by typing
  C-h v pr-txt-name

Again, your value for ‘pr-ps-printer-alist’ looks
suspiciously identical to the value in the docstring (*Help*
text) for ‘pr-ps-printer-alist’.  Unless you have a separate
printer for printing PostScript files, this expression
should be:

  (setopt pr-ps-printer-alist 
          '((default "lpr" nil "-P" "HP-Officejet-J4500-series")))

And then:
  (setopt pr-ps-name       'lps_06b)
would be:
  (setopt pr-ps-name       'default)

Note that because this value is the default that Emacs sets,
you do not have to include this expression at all.  Simply
confirm that the value is ‘default’ by typing
  C-h v pr-ps-name

Again, confirm that each ‘setopt’ expression has the correct
value by placing point after each expression and evaluating
them by typing C-x C-e.
