I rebooted the computer and printer, reconnected to the network, cancelled and re-sent print jobs to the printer, etc. Nothing works. I don't get an error message on the printer. I only see Pending on the display on my laptop. I have been using this ...

My PIXMA TS7720 goes to sleep after a few minutes and when I send a print job to it, I have to power it back on and re-send the job. Is there a way to lengthen the time it waits to go to sleep or completely disable this feature?
