I think it's reasonable to demand a certain level of legibility. > For me, printing the screen image obtained from my chosen page from > the Print Preview of FireFox gave an acceptable output with a Custom > Scale. It helped to choose Landscape mode. The landscape mode changes the output from a very tall image printed on a portrait page to the same image printed across it instead, reducing the scale by the golden proportion. > 'lp -d.....' benefits from fiddling with the scaling= option and from > orientation-requested=4. This gets very involved. Having tried feeding convert with the image, I see that it can produce a pretty faithful PDF which suffers only from the usual problem of being overtall. If I was going to indulge in this very often (which I'm not) I think it would be worth writing a script to run convert on page-size slices of the image, outputting them as PDFs, and collate them into a conventional multipage document with pdftk. It would be fairly simple to compute the y-size by ratioing the x-size according to the paper regime, and even allow for some overlap between pages (because one doesn't know where to slice in between lines of text). PS what's a backdoord malward? Cheers, David.
