[Page size for printing frozen at A4]

I did the following:

Create a document with Custom size 150 x 100 mm

Go to File -> Print

Select Properties.

Select paper size 4" x 6" 10x15cm

Click OK.

Click OK.

The Print Preview shows a paper size of A4; the Properties aren't saved.

However, the problem went away when I changed printer and the changed back again.

 

 

[Page size for printing frozen at A4]

I tried printing on 100 x 150 mm photo paper, but Publisher 4.7.0.192 refused to change the paper size from A4 despite setting it to 100 x 150 mm.
