    2424    - 1.20alpha2 : 
    2525     
     26        - Now software accounting method reads accounter's 
     27          answer until a line with a single integer is  
     28          obtained or until all of its output has been read. 
     29          This should fix the problem some people have 
     30          when strange locale related messages are sent 
     31          when running subprocesses (Solaris only ?). 
     32           
    2633        - First version of ESC/P2 analyzer. Seems to work 
    2734          ok at least with 'epson', 'epsonc', 'eps9mid'
