We have a Canon Imagerunner 5020i in the building and for some reason the past several weeks printing to it has reduced to a crawl. I read up that new UFR drivers released by Canon can help with printing, especially PDF's. For some reason Canon did not release this driver for this specific model. Does anyone know if drivers for another model would work for it? Basically we have tried PCL5e/PCL6/PS and all of them still print slow (1 page every 15-20 seconds and it takes 20 minutes to actually send the document to the printer). We've tried with other Imagerunners in the building, same response.
