You can try using StringBuilder  -      final StringBuilder sb   new StringBuilder         sb append  SHOP MA n        sb append  ---------------------------- n        sb append  Pannampitiya n        sb append  09-10-2012 harsha  no  001 n        sb append  No  Item  Qty  Price  Amount n        sb append  1 Bread 1 50 00  50 00 n        sb append                               n            To use StringBuilder as String   Use  toString    method       System out println sb toString

I think you are making it too complex  AttributedString is used when you want to store attributes - in Printing Context  But You are storing data inside that  AttributedString  Simply  store your data into Document object and pass properties like Font  Bold  Italic everything in AttributedString   Hope this will be helpful  A quick tutorial And  In depth tutorial

Adding  r n between the Strings solved the problem for me  give it a try  On pasting dont include the      for excluding  Eg  Option01 r nOption02 r nOption03 this will give output as  Option01 Option02 Option03
