[RESOLVED]cant print from report which created at not the same time as the designer

i have problem with printing my crystal report.some of my report can't printed and some can.there is no differences(in coding) between one and another. but the diference is just in the way they created. the one that can print is created when the designer created. and the other create not at the same time with the designer. and there is no error reported.
is there anything i can do to avoid this?
thanks in advance for your help. :p

Both were created using the report designer, but at different times, right?

That should make no difference whatsoever.

Does this happen in both design and runtime?

i mean,when we insert crystal report designer,vb always as wether we want to add viewer or not.report that display in first viewer(create at the same time as designer) can print. and then i create new form with new viewer and create new instance of the first report.Nah,this second viewer cant print.
i have enabled both print button and when i run them they both can click.but the first appear one form again that indicate the viewer is printing.but the second isnt.

finally this problem solved by myself :D
i forget to uncheck option "no printer" in printer setup.
if you face this problem like mine,you can find this option in :
open your designer
right click on the report
choose "printer setup"
then uncheck "no printer" option
many thanks for all of you that have pay attention to my problem...
