I try to install Net::CUPs from cpan shell i got this massage: Running install for module 'Net::CUPS' Running make for D/DH/DHAGEMAN/Net-CUPS-0.61.tar.gz Has already been unwrapped into directory /home/casaburi/.local/share/.cpan/build/Net-CUPS-0.61-_zchLs No 'Makefile' created , won't make Running make test Make had some problems, won't test Running make install Make had some problems, won't install SO i try to install it manually getting this error massage: Net::CUPS Configuration Running cups-config ... failed. Net::CUPS requires the Common Unix Printing System. Check your system configuration and then attempt the configure process again. (i have perl v5.10.1 on Ubuntu) Can anyone help me please ? i'm going crazy !

On Ubuntu, you should first use the apt-get or Synaptics Package Manager to install Perl modules. Why? Because Ubuntu often has many dependencies, that are required before installation. I would look thru your menu, and find Synaptic's Package Manager, run it and search for "perl Net::Cups", then install all the dependencies.

Also, unless you have the latest Perl version 14.x installed, the Perl that comes with Ubuntu is older, around version 10 or 12, and the latest Net::Cups may not work at those Perl version levels. You may need an earlier release of the Net::CUPS module to be compatible. See Cups on Ubuntu

Thank you so much, now CUPS works fine !! I am able to open a file and it printed content in the terminal. I'm not able to print that content (of the txt files) in a scrolled GUI windows. Can you suggest me the correct sintax to link print@line in $mw....???

sub open_file {my $open = $mw->getOpenFile(-filetypes => $types_OPEN,
                              -defaultextension => '.sff');

                     $read_fh = IO::File->new("$open",'r');
                     read_text($read_fh);
}

sub read_text

{          
          
       
local $read_fh = shift;
        my @lines;
        @lines = <$read_fh>;
        print @lines;
MainLoop 
}

You can't print in the $mw directly, but you can print to a Scrolled Text Widget in the $mw.

#!/usr/bin/perl
use warnings;
use strict;
use Tk;

open (FH,"<$0") or warn "$!\n";
my @lines = <FH>;
close FH;

my $mw  = MainWindow->new(-title=>'Colored Text');
$mw->geometry(($mw->screenwidth-10) . 'x' .
             ($mw->screenheight-10) . '+0+20');

$mw->fontCreate('big',
   -family=>'arial',
  -weight=>'bold',
  -size => 25 );

my $text = $mw->Scrolled("Text",
          -scrollbars => 'osw',
          -background => 'white',
          -font =>'big',
      -wrap => 'none',
                          )->pack;

$text->tagConfigure('greyline', -background => 'grey95');

my $toggle = -1;
 for (@lines) {
      my $greyline;
      if( $toggle == 1 ){ my $greyline = '' }
         else { $greyline = 'greyline' }

     $text->insert('end',"$_",$greyline);
     $toggle *= -1;
 }

MainLoop;
