How can I print A3 format in SAP

My printer is HP LaserJet 5100

Note I can print ms word document in A3 format but I can't print A3 format in SAP

My output device setting are:

DeviceAttributes:
Device Type = THSAPWIN: MS-Windows-Printer via SAPLPD
Device Class = Standard printer
Access Method:
Host Spool Access Method = S: Print Using SAP Protocol

When I print SM50 output and select format X_65_255, it can print successfully but its format is A4.

What may I do wrong? Please help me how to set up for A3 printing in SAP.

Ps. Do I need to assign A3 format to be default format in that printer?

Is this task for BASIS or ABAP?

In printer settings - SPAD - tray info - you can give the Page format for that tray .
did you try setting that ? Try setting DINA3.
