I recommend performing a nozzle check first. Please click HERE for the steps to print the nozzle check. Once the nozzle check prints, please click the link in step 6 to compare you nozzle check.
If the nozzle check from your G4210 does not look like the sample nozzle check, please click HERE for the steps to perform a nozzle cleaning.
If the nozzle check prints correctly, please try to make a copy directly from the printer. This will help narrow down if there is a hardware or software issue.
We look forward to your reply.
I recommend performing a deep nozzle cleaning. Please click HERE for the steps.
If the printer still does not apply ink to the paper, the printer may require service. Please call us at 1-800-OK-CANON (1-800-652-2666), Monday - Friday, 8:00 AM - 8:00 PM EST so we can look into your service options.

Just in case this might help someone. I have tried numerous troubleshooting efforts on my Canon G4210 this weekend. I use a mac laptop so here's a run down of what I have tried with no results.
I tried resetting my mac's printing system. Didn't help. I tried resetting my router. Didn't help. I tried using the disk utility first aid. Didn't help. I tried calling Canon. No answer, but I'll try again tomorrow. I tried using the copy mode to scan a document to see if it would print. Didn't help. I tried printing from my other mac. Didn't help. I'm a senior / not tech savvy but I did everything I could think of and nothing has helped me. I did do a nozzle check and it came out perfectly. But nothing else prints on the paper. Just spits out blanks.
