Comment 1 for bug 1398510

Even after running the 3-stage 'Clean' process several times printer fails to print half (in height) of one of of the lines of fonts.
Attachment 1 shows output directly after 'Clean 3'. Only the top line of text is affected.
Attachment 2 shows the result of printing a full page of text:-
Note. It seems that some fonts are affected more than others, for example the last seven lines, printed in Ubuntu Medium, seem to be error free. Could this be a font, and not a printer problem?
