[vox-tech] Printouts cliped, how to fix?

[Mark K. Kim]

The printer was probably waiting for the paper eject command (ASCII #12,
"Form Feed"), then it timed out and ejected the queued page.  To print
directly to the raw device, first send the file to the printer like this:

   cat file.txt > /dev/lp0

then send paper eject command ("form feed") to the printer like this:

   echo '<Ctrl-V><Ctrl-L>' > /dev/lp0

where "Ctrl-V" and "Ctrl-L" are Ctrl key combination, typed under BASH.

On a separate note, when you print using `ls | lpr`, and then you print
using `ls > /dev/lp0 && echo '<Ctrl-V><Ctrl-L>' > /dev/lp0`, do you notice
any difference besides the text not being cut off on the top and right?
For example, is the text shifted to the left or the bottom?

Good nite!
