Please go to Reporting > Reports > Support (tab) > Medical. In here run this for all years, or choose a year group and click choose.
Once the report is run there is a tick column down the right hand side, this is who will be printed. Simply untick the students you do not want to print, or click the header to untick them all and tick the ones you wish to print.
Now when you print only the student ticked will export.
