I have a document imported from Autocad with A4 and A3 pages in one file (about 60 pages), but when I print it, page resizing to pagesize property. Adobe Reader detect if it A3 and print it as A3. It will be great to have this function here.
SumatraPDF aims to be a lightweight fast reader / viewer of many book formats
Printing is limited to passing the selected pages to the selected windows print driver.
There are limited manual options to affect scale such as fit, but no resize to xx% nor any way to let the printer automatically swap paper sizes.
In AutoCAD you can generally only send one plot at a time with a given set of scale / paper etc.
In Sumatra PDF you can send a range of pages to A4 and a range of pages to A3, so if every second page needs to be different you would set range for A4 to 2,4,6,8,10 and then set range to 1,3,5,7,9 to A3 or for drawings with multiple schedules however they are spaced out.
