Problem Printing Lines

Hi There
I hv made invoices in crystal reports for the Exports Management System. If I print the invoice from one of the clients machine it is bieng perfectly printed, but giving the print command frm another machine suppreses the lines (object) I hv put in the report.

what is the problem? is there is the problem with the report, preinter or software I am not getting the solution for it. user has to print report frm machine which is not meant for the Exports dept.

Help will be appriciated
