This program is for those BBC owners with a Seikosha GP80, 100
or 250 dot matrix printer. It allows high resolution screens to
be copied to the printer at the touch of a button.
The routine loads into a reserved section of memory and
is accessed by a three-line addition which you simply tack on to
the end of your graphics program.
It will produce a screen copy in modes 0, 1, 2, 4 and 5, and has the
option of altering which logical colour on the screen will be
represented by black on the printer.
If you don't want to use up half a printer ribbon in one go it
is better to set the printout background colour to white, so
that all black sections of the screen appear white on the copy. This
does not affect the rest of the colours, which appear in shades of
grey.
The routine took approximately six minutes to produce a mode 0 dump
with most of the screen used.
Instructions were clear, but the manufacturers do recommend
that users read their printer manuals carefully before using the
copier. Even so, the routine was very easy to use, only requiring
the press of any key to produce the printout.
