[TI 00/4A Printing and scrolling--help!]

I am new to the TI 99/4A and there are three areas relating to scrolling and printing that mystify me. Can anyone help?

(1) Once I've written and saved (on disk) an entire TI-99/4A program in BASIC, is there any way

then

to print it from the computer--without entirely redoing it--starting all over again, this time beginning with PRINT #4: "PIO", followed by the whole program rewritten--with each line beginning PRINT #4: "[TEXT]" ? Isn't there some kind of command one can introduce at the end of the original program to print it as is? (I have checked four or five old textbooks for the TI-99/4A and BASIC programming on the TI-99/4A and none of them answers this.)

(2) When a BASIC program I've written is fairly long--too long to appear in its entirety on the monitor screen--it of course scrolls to the end. How can I get it back to the first line, so that I can go through the whole program line-by-line to make sure there are no logic errors or to make corrections/additions? I don't want to remove lines or edit yet--I just want to return to the first entry (line 10) so that I can proceed line-by-line through the entire program. As is, I can only see the final 20 or so lines on screen! I have tried the arrow keys, the back key, etc., with no effect. (Again, none of the books seems to address this.)

(3) Where can I purchase pin-holed paper rolls that will work with an Epson MX-80 printer??
