The Canon Printer Not Printing issue can be brought on by a variety of factors. Computer issues or a backlog of pointless print jobs can be the first. On the CD-R Tray, however, the printable DVD/CD may not be placed properly. It is also possible that the gadget is not yet operational or that it is incorrectly attached. Alternatively, the issue could be with the ink tank of the printer. The printer driver may not have your device selected, for example. https://www.canonprintersupportpro.us/blog/fix-canon-printer-not-printing-issues/
