c# - Crystal report not printing as it shows while design time when using PrintToPrinter method -

hi intelligent peoples,

i stuck @ problem , cant find solution anywhere on internet.

problem : printtoprinter method not print same design. print out same when printing preview of crystal report in crystal report viewers, user don't want click print on windows form , press print again in print preview(crystal report viewer). want print report directly printer without asking user again.

page setup:

page size : 8.5*8.5 inches.
no printer(optimize screen size) : checked
dissociate formatting page size , printer paper size : checked
user defined size : selected

printout crystalreportviewer desired. printed paper printtoprinter method comes different.

please me, stuck.

edit: following event handler btnprint. want user click on btnprint on windows form once , want print out. no other step. print comes out not expected.

if open crystal report viewer on click of btnprint after user clicks on print button on crystal report viewer , after selecting printer clicks print button on print dialog, printer prints expected. eliminating steps doesn't prints ago.

hope understood @amazing
