Blade sed , awk script for printing matched line before regular expression

hi All ,

I am having a large file with lots of modules as shown below
###############################################

Code:
 module KKK 
kksd 
kskks  
jsn;lsm
jsnlsn;
Ring 
jjsjsj
kskmsm
jjs
endmodule

 module llll 
1kksd11 
k232skks  
j33sn;l55sm
js333nl33sn;
Ring 
jj33sj4sj
k33sk33msm
j33js
endmodule

################################################

I need to match Ring regular expression and script should print corresponding module related to that "Ring" expression ...Ring lies in different modules ...

Output file

Code:
Ring :  module kkkk 
Ring : module lll

#################################

I am using this one liner
Code:
awk '/Ring/ {print  x} {x=$0}' file

but it is priting one line above the Ring expression ...
I need to find out the corresponding module of the Ring where it lies and create a output file

Please help me out

NAME
paps - UTF-8 to PostScript converter using Pango SYNOPSIS
paps [options] files... DESCRIPTION
paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves through the pango ft2 backend. OPTIONS
These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below. --landscape Landscape output. Default is portrait. --columns=cl Number of columns output. Default is 1. --font=desc Set the font description. Default is Monospace 12. --rtl Do rtl layout. --paper ps Choose paper size. Known paper sizes are legal, letter, a4. Default is A4. --bottom-margin=bm Set bottom margin in postscript points (1/72 inch). Default is 36. --top-margin=tm Set top margin. Default is 36. --left-margin=lm Set left margin. Default is 36. --right-margin=rm Set right margin. Default is 36. --help Show summary of options. --header Draw page header for each page. --markup Interpret the text as pango markup. --encoding=ENCODING Assume the documentation encoding is ENCODING. --lpi Set the lines per inch. This determines the line spacing. --cpi Set the characters per inch. This is an alternative method of specifying the font size. --stretch-chars Indicates that characters should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops behaviour. AUTHOR
