Redefining plain style

Some commands, like \chapter, use the \thispagestyle command to automatically switch to the plain page style, thus ignoring the page style currently in effect. To customize even such pages use the fancyplain page style. This page style sets up fancy for normal pages and in addition redefines the page style plain to conform more to the page style fancy. For instance, if all the page numbers are bold, you may want this on the first page also. You do this with the command 

\pagestyle{fancyplain}
Note that this does not issue a \pagestyle{plain} or \thispagestyle{plain} command. This is either done by (for instance, for the first page of a chapter in the book class), or you have to do it explicitly with the 

\thispagestyle{plain}
command.

The redefinition of the plain style is done with the command 

\fancyplain{plain_value}{normal_value}
inserted into all the appropriate arguments. As an example, let us redefine the plain style for the report in Section [*] by making the page number bold.

The leftheader definition: 

\lhead[]{\bfseries The performance of new graduates}
changes to 

\lhead[\fancyplain{}{}]{\fancyplain{}{\bfseries The
   performance of new graduates}}
Note that the first argument of both \fancyplain commands is empty, since the redefined plain style has an empty leftheader. (The \fancyplain{}{} is superfluous but for symmetry reasons it is given in this example.)

The left- and rightfooter definitions change more. For instance, the leftfooter definition changes from 

\lfoot[\thepage]{From: K. Grant}
to 
\lfoot[\fancyplain{}{\bfseries \thepage}]
      {\fancyplain{}{From: K. Grant}}

Carrying out these changes for all six fields, we get the code: 

\lhead[\fancyplain{}{}]{\fancyplain{}{\bfseries The
   performance of new graduates}}
\chead{\fancyplain{}{}}
\rhead[\fancyplain{}{\bfseries The performance of new
   graduates}]{\fancyplain{}{}}
\lfoot[\fancyplain{}{\thepage}]{\fancyplain{}{From: K. Grant}}
\cfoot[\fancyplain{\bfseries \thepage}{From: K.
   Grant}]{\fancyplain{\bfseries \thepage}{To: Dean A. Smith}}
\rfoot[\fancyplain{}{To: Dean A. Smith}]{\fancyplain{}%
   {\bfseries \thepage}}
\setlength{\headrulewidth}{0.4pt}
\setlength{\footrulewidth}{0.4pt}

For the ``fancy plain'' page style, the thickness of the lines is defined by

\plainheadrulewidth and \plainfootrulewidth
(both default to 0pt). Observe that you may have different ``fancy plain'' page styles for even and odd pages.

To use the ``fancy plain'' page style, define these macros; in the preamble, include 

\usepackage{fancyheadings}
\pagestyle{fancyplain}
and invoke the page style ``fancy plain'' with 

\thispagestyle{plain}
where desired.
