I've just realised that a post that I've put on the forum elsewhere,should really have gone here, so this is it:
This is a problem that's slowly driving me mad. My desktop machine has without warning stopped printing, from Firefox, in landscape format. Portrait is fine, but any failed prints block the print queue, until removed. I normally print to an HP colour laserjet pc1515n, which I've been blaming for the problem. However, the laserjet is currently down while I'm waiting for the tardy delivery of a new toner cartridge, so in the interim, I've resurrected my old Canon inkjet printer. Lo and behold, this suffers exactly the same problem, so the laserjet is not the problem. It would appear that some update, perhaps of Firefox is responsible for this. Any idea's anyone? I don't do much printing from other than Firefox, but I've just tried printing from Gwenview, and it's fine in portrait, but not in landscape, while printing the same file. Cups, perhaps?
Sorry for the duplication
