This problem of loss of the first few characters also occurs with
some 80 column cards and also the BASIS 108.  The reason is that as
the screen scrolls after a new line at the bottom, a few characters get
lost.  Often the first character is received and repeated, with the 2nd
and a few more chars lost.

The solution for screen problems is to tell UNIX to do a
stty nl2
You may need to do a stty cr2 for the printer.
