ok, I found how _I_ could do it:
just run a macro line
(Alt-F11 Ctrl-G - insert line below - press enter)
for each aSheet in thisWorkbook.Sheets: aSheet.PrintOut: next
But this would be for a customer, so macro won't go.
(file are generated so macros won't carry on [we tried that], but all formatting - will)
Any other options?
