98. Printing listings (2)
    ~~~~~~~~~~~~~~~~~~~~~
Here is another handy little routine from Peter Osborn, using the Perforation
Skipover facility in your printer. This leaves a few blank lines at the top
and bottom of each fanfold sheet, thus avoiding listing lines being bisected
by the perforations. It is shown as a string of VDU codes on KEY0, and the
cancel code is on KEY1. I have assumed that the formlength has first been set
to 11", (the norm), or 12", either on the printer dipswitches or by the
Esc"C" command.

The procedure is to set your paper up so that the print head is approximately
N/2 lines from the top of a sheet, where N is the total number of blank lines
to be skipped. (Ie if you want 3 blank lines at the top and bottom of the
pages, then N=6.) Now switch your printer on, press <f0>, and then LIST your
programs as normal, using <Ctrl><B> and <Ctrl><C> to switch the printer on
and off. You can cancel the skipover with <f1>, to avoid odd things happening
with, say, Wordwise, which can set its own top and bottom spaces. This
routine apparently works on all Epson-compatible printers, and also on the
Star Gemini 10-X.
