One work around I have successfully used for the pagebreak issue was to edit the form that the document is used to print.
Open the form in Designer and go to the bottom of the form. Then on the toolbar click Create| Pagebreak. This will insert a hard pagebreak at the end of the form which will be recognized when using @Command([FilePrint]). Once Lotus produces a fix and it is applied, just delete the pagebreak from the form.
One caveat is that some extra blank pages will be produced if the documents are printed b selecting File | Print.
