What is a EOF or NL

[Bob Falanga]

I have been a long time trying to print anything on freebsd, as some know.
Everything seems to be working new but nothing is printed. Today I reboot
the computer and behold a page printed.  This implied to me that the printer
never receives a New Line or EOF or whatever the printer requires to proceed
printing what it has just received.
My question is where do I configure an option to print.

Thank you so much,

Bob Falanga
