You are correct. You can mention the sheet no. in 'Sheets from' in case you want speific sheets, for example: if you want to have booklet printing of file containing 100 pages then it will have 25 sheets, to get middle page: enter 25 to 25 in 'Sheets from' .
Hope this will be helpful to you.
Thanks sonal. I guessed it was like that. I'm trying to print a 229 page booklet and, as I say, the printer screwed up. When I looked at the partial print-out more thoroughly I found that it had printed the reverse sides upside down, which is a much worse problem. The simple solution would be to print only the front sides, put it back in the printer and print only the back sides but inevitably the printer double feeds from time to time and there is alot of wastage which ever way I do it.
Any more ideas on getting the two sides the right way up?
