Yes, that's a problem, but I guess you could always
argue that the user must have read the documentation
and decided this is what they had in mind. :-)

I haven't run your program yet (still fixing bad line
breaks caused by a 1960's era newsreader that stubbornly
insists on fitting everything for output to 80-column
punch cards), but have you taken into account that a
location of (0,0) puts part of the output in the
non-printable portion of the printer?

I've always found that a decidedly non-general printer
fudge factor is also required. :-(

Cheers,

David
