I did remove lp1 and turned on the printer. lp1 was not recreated, and the
printer works fine. I stupidly created lp1 by copying a file there after the
original character special device was gone. I still don't know how I got
/dev/usb/hiddev0, but it probably doesn't matter.

What I used was a few engraved 19th-century postage stamps.

Good idea. If I scan to a TIF at 600 dpi, the Brother's quality matches that
of the Epson's 300-DPI JPG, even if I later convert the Brother's TIF to a
600-dpi high-quality JPG with other software. So the Brother gives good
quality when scanning as TIF but not as JPG. Thanks.

But when I tested some fine engraving (like a dollar bill), it was less sharp than I get with my old Epson Perfection 2400 (from 2004). In both cases I asked for 300 dpi and set JPG quality as high as possible. The Brother at 600 dpi didn't match the Epson at 300 dpi. Would installing the Brother scanner driver be an improvement, or is this just a limitation of the hardware?
