Is it possible to generate lightning address / invoice that can be used multiple...

I'm planning to attend art exhibition, displaying some of my pieces, it's actually for the 🍕 coming soon.

I can easily print QR code with my on-chain BTC address.

I would like to print QR code with my lightning address to receive SATS.

Is it possible?

To have a printed out QR code with to receive SATS on lightning would be a dream.

Workaround: use a URL shortening service, that redirects QR code to something that generates invoice on the fly...

Yes, it's possible, you can use a LNURL or even a LN address.

In my case, I would encode my LN address in a QRCode ([email protected]) and that should work. When a LN reads an address like this (looks like an email address) it goes to the domain getalby.com and asks for an invoice for the user bordalix. It then pays the invoice.
