Just tried to verify it, it does not work with dynamic values:

https://github.com/cssinjs/jss/tree/master/packages/react-jss#dynamic-values

Sample code:

import * as React from 'react';
import injectSheet from 'react-jss';

interface IStyles {
	root: string;
	rootDynamic: string;
}

const styles = theme => ({
	root: {
		padding: 20,
		color: theme.colors.primary,
		[theme.breakpoints.up('sm')]: {
			padding: 10
		}
	},
	rootDynamic: (props: IPrintNameProps) => ({
		fontSize: props.size
	})
});

export interface IPrintNameProps {
	name: string;
	size: number;
	classes: IStyles;
	style?: React.CSSProperties;
}

class PrintName extends React.Component<IPrintNameProps> {
	public render() {
		return (
			<div className={this.props.classes.root}>
				test
			</div>
		);
	}
}

export default injectSheet(styles)(PrintName);

Oh and if I don't define classes prop, the I the following [ts] Property 'classes' does not exist on type 'Readonly<{ children?: ReactNode; }> & Readonly<IPrintNameProps>'.

So something is wrong here, it should inject those props. I'm on [email protected] btw.

Can confirm with Saturate, this one and the definitions in @types/react-jss do not support dynamic values.
