It lists all supported PJL variables, and neither PAPERWIDTH
nor PAPERLENGTH
are in the document. For some models, PAPER
can be set to USERDEF
or USERDEFINED
, but I haven't figured out how to specify actual numbers.

Looks like maybe the printer interprets a proprietary format for custom page sizes.
Edit: I tried it myself (on an HL-L2320) and I used Wireshark to verify the driver was setting PAPERWIDTH
and PAPERLENGTH
and not PAPER
, and it just printed the image where the upper-left corner of a letter sized page would be.
I printed this 4×6″ PDF on my Mac using the standard drivers, and captured this packet trace which has the following in the PJL header:
@PJL SET ORIENTATION = PORTRAIT
@PJL SET PAPER = COM10
COM10 is the size of a number 10 envelope, which is 4⅛×9½″. I haven’t tried decoding the image data, but I wonder if the driver just picks the next largest standard size and then offsets the image to center it horizontally?
I have a Brother HL-2320D, which can print on custom page sizes when used via a Mac. (In particular, I’m trying to print on 4x6 cards, but I’m sure other sizes will be useful in the future.) However, it seems that brlaser hard-codes a list of paper sizes that it supports.
It looks like this is because brlaser uses the
SET PAPER
command to tell the printer the media size. Some rummaging around the Internet turned upSET PAPERLENGTH
/SET PAPERWIDTH
(in tenths of a point, I think); but I’ve been unable to find any documentation from Brother that their printers all support this command, and I’ve not tried it on my own printer yet.
