I want to popup only that pdf templates which is assigned to that user not other templates when user click on print as pdf in quote module. is it possible??
Have a look here

Watch out because that applies to all modules with “Print to PDF” function. The templates get selected with a "WHERE type = ‘Contacts’ " but if you add a condition for Assigned user, make sure it applies only on the Quotes module, if that’s what you want.
