RFR: 8270609: [TESTBUG] java/awt/print/Dialog/DialogCopies.java does not show instruction [v4]

[lawrence.andrews]

> 1) When the test is executed via jtreg user can see only print dialog with no instruction to the user. User has to see the test case to see the instruction and perform the test . 
> 2) With this fix User is instructed what he/she has to do with the print dialog.
> 3) I have added both success instruction as well as failure instruction.
