giclee prints (of artwork) require that photo submissions of art must be 300 dpi.

I know nothing, so to book, PowerShot A 620 seems to max at 2000 something. Divided by 8.5 or 11 is below 300.
Look, I want to shoot just one thing, drawings, from original 8.5x 11 to get 300 dpi do I need a new camera?

Further there is a 'superfine' setting I spotted somewhere in the book. Might that help?

merci Q

Yes superfine will help.

You could always upsample with a free software like Irfanview

cheaper than a new camera...

There are separate settings for quality and size.

You should have your resolution set to 3072 X 2304, which is your highest resolution. That will give you an 8.5 X 11 crop of 271 PPI.

You also have choices of Normal, Fine or Superfine for quality. This setting determines how much the image is compressed. You would want to use superfine for submitting art.

The native resolution of 271 PPI would probably be a little better than an upsample to 300 PPI, but if they require 300 PPI you will have to resample in software to that. Use a program to resample that lets you select quality and use the highest quality it offers when you save the image.

The freeware Irfanview that Buck suggested is excellent for that. It defaults to the Lanczos resample filter which is as good as it gets without going to pricey software. Make sure to use 100% quality in Irfanview when you save after your resample.

Also keep in mind that none of the resolution choices available in any camera give an image that is exactly the right shape for 8.5 X 11. You have to crop to the correct height to width ratio before you resample to 300 PPI. You can also do that in Irfanview.

The A620 is an excellent camera for what you are doing and you probably wouldn’t do much better with anything but a DSLR. Even then you would have to crop and resample to get an 8.5 X 11 of exactly 300 PPI.
