I have installed both the LPR and CUPS wrapper drivers, but I cannot print. (Linux®)
Your printer will return errors with smaller or bigger media width setting.
Change the paper size setting from the cups web interface ("http://localhost:631/printers" -> "Set Printer Options") and perform "Print Test page" (The setting will be saved when you perform a printing.)
Change the paper size parameter in "/usr/local/Brother/PTouch/inf/br(model name)rc" to the paper width.
The available parameter value is in the /etc/cups/ppd/(model name).ppd file.
This action will change the default printout paper size.
