Custom paper sizes were so easy in old Windows versions, but Windows 10 is
so frustratingly "friendly" that such settings are incredibly difficult to find. Argh!
TL;DR: How can I add paper sizes in Windows 10?!
My printer (Brother MFC-J895DW) is on my home LAN, and my Windows 10 has detected it just fine. However, only certain paper formats are offered, and I see no way to add custom sizes to this list. Specifically, I want to add "Envelope C6".
Googling gave this Microsoft help page which says to open the printer properties and then click the tap "Paper". Of course, my Windows does not have a tab "Paper", and the tab "Device Settings" that lets me select the paper sizes only allows that same, fixed list:
The "Brother Utilities" and "Brother Control Center 4" that can be installed as part of the full driver and software package do not offer any controls for paper sizes; these programs only offers settings for the scanner function.
Googling more, I can see that other people have printers with more paper options. This one has the "Envelope C6" I am looking for. Of course it would be silly to have to purchase a new printer just because this list is different! Surely even Windows 10 has a way to specify these sizes??!
