I have this strange On again and Off again issue. When printing from lightroom to my LF printer (Canon 8300), Lightroom launches the operation to generate output but the output is never sent to the printer.
If I change the printer, the print output from LR is sent to the printer. If I use another program to print to my LF printer it works.
Random things I have tried to fix this are; closing LR and relaunching, rebooting the computer, changing print size/properties. None works directly but as I mentioned above, the problem goes away by itself and then comes back.
