To create printers pairs for A4's (folded to A5) Is easy because I have an A4 printer but it won't let me alter the page size!
I'm using the print booklet postscript function to create printers pairs. Currently I have to boot up an old Mac with cs4 on it to complete this task.
Help would be appreciated!
