Smooth Print makes it easy to print labels or receipts from mobile devices to Brother label printers.

Overview

Smooth Print is an app for printing labels or receipts from iOS and Android™ mobile devices to Brother printers.

Smooth Print works from a user's own web app or mobile app via a URL scheme.

*Smooth Print for iOS is available on the App Store.
*Smooth Print for Android™ is available using the link at the bottom of this page.
*Make sure you are using the latest version of Smooth Print.

Setup Summary - Order of Tasks

Below is a brief overview of the setting up process.

[Administrators]

  1. [1] On a Windows PC, prepare a template file and a media settings file to use with Smooth Print.
  2. [2] Save the template file and the media settings file to an HTTP server.
  3. [3] Prepare a web app or a mobile app, then embed the URL scheme in that app so it can connect to Smooth Print.

System Structure

System configuration diagram

*Smooth Print downloads template files and media settings files via a URL scheme.
*Smooth Print prints by reflecting each parameter (text/barcode, number of copies) from the URL scheme to the template file.

Setting up Smooth Print

[1] On a Windows PC, prepare a template file and a media settings file to use with Smooth Print.

[How to create a template file]
  1. a. Start P-touch Editor to create a layout LBX file.
    P-touch Editor
  2. b. Type the name for each piece of text or barcode you add to the layout in the Object name field.
    P-touch Editor
  3. c. In the P-touch Editor menu, click File > Save As and select "Template (*.lbx)" as the file type.

*Supported fonts: Atlanta, Belgium, Bermuda Script, Brussels, Brussels Condensed, Connecticut, Germany, Helsinki, Helsinki Narrow, Istanbul, Letter Gothic, PT Utah Condensed, San Diego, US, Utah

[How to create a media settings file (BIN file)]

*A media settings file must be created for each model, except for the models in the TD-4T and TJ series.

  1. a. Open the Printer Setting Tool and launch the Paper Size Setup Tool.
  2. b. Click New... to enter your label size and click Add to register a custom paper size.
  3. c. Click Options and select Save in Command File....
    Paper Size Setup

[2] Save the template file and the media settings file to an HTTP server.

[3] Prepare a web app or a mobile app, then embed the URL scheme in that app so it can connect to Smooth Print.

Configure the URL scheme as shown below.

[URL scheme]

[Required parameters]

Make sure you specify the template and media size, as shown below, and ensure that both are URL-encoded.
Parameters can be in any order.

To use a LBX file or a media settings file (BIN file) from another app, share the files with Smooth Print using the "file sharing function" (an OS standard function).
Once the file is shared, specify the file name in the URL scheme before printing.

*For PJ series, use the paper size ID for the "size" parameter.
*For QL series, use the label size ID for the "size" parameter.

[Optional Parameters "successCallback" and "failureCallback"]

Set this parameter if you want to check the print result from the user's web app or mobile app.
If you set this parameter, the printing outcomes will not be displayed in Smooth Print.
Both callback parameters must be specified and connected with "&". If only one parameter is specified, the setting will be invalid.

Parameter Description Values Example values (URL-encoded values) Example values (before URL encoding)
successCallback URL scheme is launched when printing is successful. URL string sendurlscheme%3A%2F%2F
successCallback%3Fresult%3D		 sendurlscheme://
successCallback?result=
failureCallback The URL scheme shows an error when printing fails. URL string
*Set any value to the parameter.		 sendurlscheme%3A%2F%2F
failureCallback%3Fparam%3D
abc%26result%3D		 sendurlscheme://
failureCallback?param=
abc&result=

To run the example value above, the web app or mobile app must support the URL scheme of "sendurlscheme".

If the web app or mobile app fails to launch, the result will be shown in Smooth Print.
*When printing is successful, the URL scheme used by Smooth Print is "sendurlscheme://successCallback?result=SUCCESS".
*When printing fails, the URL scheme used by Smooth Print is
"sendurlscheme://failureCallback?param=%E3%81%82%E3%81%84%E3%81%86&result=ERROR_PRINTER _NO_SETTING".

For the list of error codes to use with callback parameters, see [Brother Print SDK error codes].


URL Encoding

Parameter settings must be UTF-8-encoded and URL-encoded, including colons and slashes.

File names are case-sensitive except when they are used in Android™ local paths.

Configure Print Settings in Smooth Print.

[Cut Options]

Select Cut Option on the Smooth Print home screen, then activate or deactivate the cut option.

*Cut options are available only for models that support an auto cutter.

*"cut the end" is not supported with TD-4T and TJ series.

Cut option Description Default
auto-cut Automatically cut the paper after each page. Enabled (This setting remains enabled until it is changed by a user.)
cut the end Automatically cut the paper after the print job. Enabled (This setting remains enabled until it is changed by a user.)
Cut after the specified number of pages Cut after the specified number of pages. 1 (This setting remains enabled until it is changed by a user.)

[Print History/Error Log Settings]

Select Print History/Error Log Setting, then activate or deactivate the log saving function.
When this log saving function is turned on:

- A log file is created in a specified location when a user prints something for the first time.
- Log data is added to the log file every time a user prints.
- A new log file for that mobile device is created in the same location each month.

Save print logs of successful printing

Language English
Name New log files are saved in the following format:
printLog_MM-YYYY.txt

For example, when a log file is created on 7th May 2023,
the file name is "printLog_05-2023.txt"
  • A log file includes:
    Print date and time Example: 05-07-2023_11-14-02
    URL scheme Example:
    brotherwebprint://print?filename=Template.lbx&size=26x76.bin&copies=1
    &text_TEXT=sample&barcode_BARCODE=12345

    • Save error logs of failed prints

    Language English
    Name New log files are saved in the following format:
    printLog_MM-YYYY.txt

    For example, when a log file is created on 7th May 2023,
    the file name is "printLog_05-2023.txt"
  • An error log file includes:
    Print error date and time Example: 05-07-2023_11-14-02
    URL scheme Example:
    brotherwebprint://print?filename=Template.lbx&size=26x76.bin&copies=1&
    text_TEXT=sample&barcode_BARCODE=12345
    error code Example: PRINT_CANCEL

    • *Print log contents are added to the same TXT file throughout the month. If new print information fails to be added to the existing log file, a new log file will be created with a version number (1, 2, …) at the end of the file name.

    *If the print log file cannot be saved, the following message appears in the web app or the mobile app:
    - Message title: Unable to save.
    - Message body: (N/A)
    Print data may fail to save if the mobile device's memory is full. Check the mobile device's memory and clear it if necessary.


    [Self-signed certificate (iOS only)]

    Enable this setting only if you want to print files from a website that uses an untrusted self-signed certificate.

    Select Self-signed certificate, then activate or deactivate the function.

    *We recommend disabling this setting, as websites that trust all certificates by default may be vulnerable to unauthorized attacks.
