Please check the comments applying to Windows Server 2008 R2 under the msdn article Enable or disable logging of printing events
. In addition, check if all needed assemblies
are deployed to these users where printing fails. Basically if the printing message appears, means the report is sent to the printer. If possible test exporting to PDF and printing, or printing other document to the same printer from the same client having problems.
As there is no such issue logged for Q3 2012 nor Q1 2013 WPF ReportViewer control printing, I would ask you to send us the problematic project to test it at our side. Any additional details as selected printer, installed drivers and error logs will be helpful in investigating the question.
