This problem only showed up in Mint 20.3.

When I try to print a gimp image via gutenprint, I can only see a dot in the left-hand window pane.
I cannot enlarge it in any way.

I have uninstalled, boot and reinstalled to no avail.

No, it doesn't need a lot of uninstalling.

When you open the Gutenprint window, it is expecting
a printer definition. My favorite printer is a "fake",
and is used for print to file. The HP750CM was one of the
roll fed inkjets that printed on 36" wide paper. We had that
for CAD proof-prints (if someone needed such a thing). I
got in the habit of abusing just the .ppd file for
declaring fake printers and making PostScript output.

You might already have some other kind of printer set up,
where just selecting the "Name" is enough to satisfy the
previewer.

Sadly, my Gutenprint doesn't understand the rules.
I use a Brother DCP-L3510CDW laser printer.
After much fiddling around I got its name to appear beside "Printer Name".
I usually leave it as printer.
Same PPD as I had in Mint 20.2

But the effect, or lack of it is the same.

I took a screen print and thought that I could make it available online.
Dropbox requires an address. There must be other methods but I haven't had time to search thoroughly enough.

I decided to run gimp as root. It and gutenprint ran perfectly.
That meant that it was a permissions problem.
I fixed it by changing the permissions of the cups ppd file:

$ sudo chmod 644 /etc/cups/ppd/DCPL3510CDW.ppd
