Cup over usb does not print to Brother J6530DW

[Christine Hyde]

I've tried everything I can find on the internet and on Ubuntu. Nothing works: changing parameters as per instructions, no go. cat text >/dev/usb/lp0 does not work either. Using cups the printer remains steadfastly inactive. "Catting" wakes up the printer to indicate data is received but nah.

The alternative ppd for printing over the network *works* however.

The usb cable is good: scanning works from Ubuntu.

I've upgraded oldish HP DM3 laptop to a ThinkPad T495s (nice machine) but still stuffed for usb printing with this machine. (My old HP had no issues)

Please ignore confusing comment about HP. It should have read my old HP Printer had no issues :)
