Sage 300

I am using SAGE 300 2016 and would like to be able to reprint orders after invoices have been created. I read the post about reprinting PO's so I am thinking that I probably have to do similar but do not know which forms to use and what changes are needed…

One workstation want to print to a printer that has been deleted and not default printer. This happens to a number of reports and it is not always the same printer. Any ideas of what can cause this?
