Print sizing question

Used Home & Student X8 on my Surface (Win10)for many years, printed at 100%. The Surface is no more, I've reinstalled X8 it on a new laptop (Win11) and am using the same printer, but now printouts are undersize by a few percent. Per advice on Corel's FAQ, "As in document" is selected, but no effect. I've been able to use the tiler to tweak print scale, but never had to use it before. Any advice would be welcome!
