Do the following:

The commands below are for TD-4550DNWB. Please replace "td4550dnwb" with your model name.

1. Remove any references to lpadmin from the following files:
   /var/lib/dpkg/info/td4550dnwbpdrv.prerm
   /var/lib/dpkg/info/td4550dnwbpdrv.postinst
    
2. Uninstall the CUPS driver:
   dpkg -r td4550dnwbpdrv
   dpkg --purge td4550dnwbpdrv
    
3. Unpack the cupswrapper package:
   dpkg --unpack td4550dnwbpdrv-[driver version].deb
    
4. Open /usr/local/Brother/cupswrapper/cupswrappertd4550dnwb in a text editor.
    
5. Search for the line "lpadmin -p td4550dnwb -E -v", and do the following:
   • Change "-m" to "-P".
   • Specify the full path of the PPD file (/usr/share/cups/model/brother_td4550dnwb_printer_en.ppd).
   Example:

   Before:	lpadmin -p TD4550DNWB -E -v usb:/dev/usb/lp0 -m brother_td4550dnwb_printer_en.ppd
   After:	lpadmin -p TD4550DNWB -E -v usb:/dev/usb/lp0 -P /usr/share/cups/model/brother_td4550dnwb_printer_en.ppd

   If you are using a Debian distribution that does not have lpadmin, delete all lines that refer to lpadmin.

6. Run the installation script:
   dpkg --configure td4550dnwbpdrv

   If you deleted the lines referring to lpadmin, run the installation script after adding the printer on the printer page of the CUPS Web Interface (http://localhost:631/printers).
