You should implement the print command either as a configurable string in your
application or as a external script file.

E.g. in Unix/linux there is two ways to print a file. E.g. lp or lpr. In
additon you have to be careful about deleting the file because the print system
might not copy the file to be printed and only use a symbolic link to it. So if
you print and then delete, you might end up deleting the file before it is
printed.
