It does work, but is a painfully slow process. I’ve found that rather than using the T4D03 template you use the T4L03 template. Also select printer HP10T4 and specify “Yes” to Laser printer. Then it will print 2 T4’s for the employee per page.
You may have to modify the template and find the correct starting point (placement of the T4 in the printer), but it will print ok.
