Not Dana, but when I get odd stuff out of the printer, it seems it is being held in the printer's memory buffer. I've even turned it off and on and seems to print whatever is still in there.
Someone posted some buffer flush exe file somewhere, but I found one yesterday in my color printer that kept printing random junk and half pages. In Windows 8, I opened the Devices and Printers from the Control Panel and right-clicking it showed me all the jobs still in there stacked one behind the other ("See what's printing"). Had to delete them there one by one. Drove me mad as to why they stay in there even turning the computer on and off and the printer too. More memory in your printer probably means more stuff hanging around in there too.
I know Qimage has a buffer flush and immediate kill switch on the panel above the editor's window. Shows a Red X on the printer icon which tells me a file is in the printer that I can cancel. I can click it and it will get rid of it faster and then it works normally beyond that point. It happened during some second-pass GO treatment too that I wanted out of where it was going to cover the entire page but I didn't want it too. I pulled up Qimage and hit the Red X and it stopped the GO ink spray and spit the page out.
