This printer is supported by the brlaser CUPS printer driver created, and maintained at time of writing, by Peter de Watcher. Some manual installation procedures are required before use. In Debian 10.6, version 4-1 of the driver is preinstalled, but the requisite Printer Description (ppd) files are missing and must be rebuilt.

This method does not require build tools to be installed, but a working copy of CUPS, along with the PPD compiler command ppdc must be present on the host system. It uses an existing installation of brlaser.

1. Clone the brlaser source tree into a directory of choice, using git, from de Watcher's GitHub repository. If git is not installed, the ZIP file may be downloaded as an alternative.
2. Navigate to the cloned source tree. If the ZIP file was used instead, extract the brlaser.drv.in file to a directory of choice.
3. Compile the ppd's with this command:

   ppdc -vd . brlaser.drv.in

   while in the same directory as the brlaser.drv.in file.
Several dozen files with ending with *.ppd will be generated. Take note of the location of the br1110.ppd file. It is recommended to remain in the same working directory as this file for the rest of the installation process.
4. Find the URI of the device using the lpinfo command:

   /usr/sbin/lpinfo -v

   The URI of a USB-attached printer should appear, among some other entries as something like:

   direct usb://Brother/HL-1110%20series?serial=DEADBEEF

5. Install the printer in CUPS with the following command, with root privileges:

   /usr/sbin/lpadmin -p 'Brother HL-1110' -v usb://Brother/HL-1110%20series?serial=DEADBEEF \
    -P br1110.ppd -L 'Your room' -E
   # Replace the serial number DEADBEEF with the number of your device,
   # and replace the optional location specified by the -L option as
   # appropriate.
   

   If a desktop environment is in use, the DE's control panel can also be used instead. With a web browser, the CUPS control panel (accessible from the host system at http://localhost:631 by default) is yet another way to install the printer.

The instructions above are for stock Debian systems. On some systems, the /usr/sbin part from the command may be omitted as appropriate.

If brlaser is not installed on your system and unavailable via the package manager of choice, the driver may have to be built from scratch. In this case, follow the build instructions provided at the brlaser GitHub repository. Build tools and development packages will be required.

The printer largely works and handles multi-page documents competently at full printing speed. However, the driver is unable to finish jobs that exceed the memory limitations of the printer.

The HL-1110 has only 1MB of memory, of which some is used up by the firmware during normal operation. To maximise the success rate of a print job, try to keep the print job under 800KB, by minimising the complexity of the documents being printed. Use raster images and gradient fills sparingly.

• 4-1, on Debian buster (10.6). The driver is preinstalled in Debian 10.6 under the printer-driver-brlaser package.

HL-1110 has a white and black case, HL-1112 has its colors reversed and is mainly black. "A" variant, marked as such on the box only, comes with a completely filled original cartridge. HL-1118 is a 1110 for the Chinese market, the differences if any aren't known. brlaser GitHub repository. https://github.com/pdewacht/brlaser
