LAN printing problem on ubuntu 9.04

I cannot print .pdf documents using Document viewer via LAN printer(that is not attached directly to my computer). All the time I get "Failed to print document". But printing .doc files and .txt works ok. So it is obvious that the problem is in the viewer. And indeed I can print pdfs using xpdf. Hope this tip will save somebody's time))

String formatting in java

Recently I have discovered very useful static method of java.util.String class - format( String formatStr, Object arg1, ...). Here are some examples demonstrating its capabilities that I know of:

 System.out.println("\""+String.format("%10s", "mama")+"\""); 

result:"      mama"

 System.out.println("\""+String.format("%-10s", "mama")+"\"");

result:"mama      "

 System.out.println("\""+String.format("%2.7f", Math.PI)+"\"");

result:"3.1415927"
