Hi,
unfortunately my English isn't the best, so may be I didn't understand you correctly.
If you print out the sign with i. e. MS Word5.0 you can edit the parameters
itself. So if your sign within the editor window in Word. i. e. is a PCX,
TIF or what ever, originally 1,78 inch in lenght and 0,97 inch in height,
you will find the path to your sign file with its size etc. in the editor
window of Word, and you simply can change the size i. e. in 3 inch length
and 05 inch height, and your sign 
get stretched in length and reduced in height when printing out the document.
I suppose other DOS text editors like Word Perfekt, Starwriter etc. are
working similar.
I don't know if there are software available to enlarge or reduce files
that is accessible for screenreader.

Yours sincerely

Arno
