I'm very close to deleting this program, but as I'm familiar with it and like the way it works this is my last effort to solve my problem. I assume there must be a setting I'm missing so I'm hoping for help here.
When using PDF24 as a printer driver it saves the pdf files in paper size 215.9 mm x 279.4mm. The original Word document paper size is A4 210mm x 297mm but the pdf comes out at paper size. I can't find any settings to change this. When I send the pdf to an actual printer yes it will print it on A4 paper but it looks terrible with large white margins. As the pdf documents are used for meeting agendas and minutes the look is unacceptable.
Found the solution. Goto Windows Control Panel and select Printers. Select PDF24 and click on Manage. Select Printing Preferences and under the Advanced tab, paper size A4 can be selected. I don't know how this setting got changed but it is not easy to find.
