It's saying that only PAPERSIZE and ORIENTATION from EXPR memo field is used by XFRX. Anything else in EXPR and TAG/TAG2 are ignored. IOW, you don't have to bother to remove printer related info from the reports to avoid problems with different printers.
That may not be true though when XFRX is used as ReportListener because VFP Report engine is used not XFRX directly.

>What is confusing above is that on one hand it says to NOT to delete EXPR field and then it says that XFRX DOES NOT USE printer settings stored in the FRX file.
