unable to add page number on newlmf document

Question

I tried to follow all advice I could find, esp. How can I add "page # of ##" on my document?, but somehow have been unsuccessful in inserting page numbers into my cover letter. Is the method different for newlfm documents, please?

\documentclass[10pt,stdletter,dateno,sigleft]{newlfm} % Extra options: 'sigleft' for a left-aligned signature, 'stdletternofrom' to remove the from address, 'letterpaper' for US letter paper - consult the newlfm class manual for more options

\usepackage{charter} % Use the Charter font for the document text
\sloppy
\newsavebox{\Luiuc}\sbox{\Luiuc}{\parbox[b]{1.75in}{\vspace{0.5in}
\includegraphics[width=1.2\linewidth]{logo.png}}} % Company/institution logo at the top left of the page
\makeletterhead{Uiuc}{\Lheader{\usebox{\Luiuc}}}

\newlfmP{sigsize=50pt} % Slightly decrease the height of the signature field
\newlfmP{addrfromphone} % Print a phone number under the sender's address
\newlfmP{addrfromemail} % Print an email address under the sender's address
\PhrPhone{Phone} % Customize the "Telephone" text
\PhrEmail{Email} % Customize the "E-mail" text

\lthUiuc % Print the company/institution logo

PARAGRAPH ONE: State the reason for the letter, name the position or type of work you are applying for and identify the source from which you learned of the opening (i.e. career development center, newspaper, employment service, personal contact).

PARAGRAPH TWO: Indicate why you are interested in the position, the company, its products, services - above all, stress what you can do for the employer. If you are a recent graduate, explain how your academic background makes you a qualified candidate for the position. If you have practical work experience, point out specific achievements or unique qualifications. 

PARAGRAPH THREE: Request a personal interview and indicate your flexibility as to the time and place. Repeat your phone number in the letter and offer assistance to help in a speedy response. For example, state that you will be in the city where the company is located on a certain date and would like to set up an interview. Alternatively, state that you will call on a certain date to set up an interview. End the letter by thanking the employer for taking time to consider your credentials.

Answer 1

newlfm sets the page style to empty when parsing the environment. You can override this by executing \thispagestle{plain} (or some other style) inside the newlfm environment, perhaps also with \pagestyle{plain} - there are different page styles and layouts set for the first and subsequent pages.

I propose an alternative, more flexible approach though: Rewrite your cover letter using the standard article document class and manage the layout yourself:

\documentclass{article}

\usepackage{graphicx,charter,geometry,fancyhdr,lastpage}
\usepackage{lipsum}

\geometry{margin=1in}% Set the page geometry

\pagestyle{fancy}
\fancyhf{}% Clear header/footer
\renewcommand{\headrulewidth}{0pt}% No header rule
\renewcommand{\footrulewidth}{0pt}% No footer rule
\fancyfoot[C]{\thepage~of~\pageref{LastPage}}% Centred footer

\setlength{\parindent}{0pt}% No paragraph indent
\setlength{\parskip}{.5\baselineskip}

\begin{document}

\includegraphics[width=.2\linewidth]{example-image}% Your logo here

\rule{\linewidth}{1pt}

\vspace{3\baselineskip}

\null\hfill
\begin{tabular}{l@{}}
  \today \\ \\
  123 Broadway \\
  City, State 12345 \\
  Phone: (000) 111-1111 \\
  Email: john@smith.com
\end{tabular}

\bigskip

\begin{tabular}{@{}l}
  Mrs.\ Jane Smith \\
  Recruitment Officer \\
  The Corporation \\
  123 Pleasant Lane \\
  City, State 12345
\end{tabular}

\bigskip

Dear Mrs.\ Smith,

\medskip

\lipsum[1-15]% Your cover letter text here

\bigskip

\begin{tabular}{@{}l}
  Sincerely yours, \\[50pt]
  John Smith
\end{tabular}

\end{document}

Answer 2

The lastpage approach does work for newlfm as well, see the line somewhere after the start of the letter body ( I just placed it there)

\textbf{\textcolor{blue}{This is page \thepage~ of \pageref{LastPage} pages}}

In the output it will be printed blue. The current page is referred to with \thepage and the number of total pages is referred to with \pageref{LastPage}. Change the formatting and position at will...

    \usepackage{xcolor}%
    \usepackage{lastpage}%

\usepackage{charter} % Use the Charter font for the document text
