===== Do I Need The Java Shim (AKA Hatch) For My Browser Staff Client? =====

==== Printing =====

=== I need to print unmediated (without a dialog) to multiple printers, like receipt and label printers. ===

== You need Hatch ==

=== I need to print to exactly one printer unmediated. ===

== You do NOT need Hatch ==

  * Firefox and Chrome both provide mechanisms for dialog-free printing.  
    * For example, in Firefox, it means adding an about:config boolean preference called "print.always_print_silent" with a value of "true".
  * Note: only activate silent printing after initial printer configuration.


=== I need to apply custom printer settings ===

== You do NOT need Hatch ==

  * When printing via the browser, use the browser's native print configuration dialog instead of the Evergreen/Hatch print configuration tool.

==== Offline ====

=== I create offline transactions ===

== You do NOT need Hatch ==

  * NOTE:  Offline data is stored in IndexedDB storage within the browser.  This is separate and safer than localStorage, or cookie and cache storage.


=== I manage offline sessions (upload batches) === 

== You do NOT need Hatch ==

  * See also note from above
  * NOTE: uploading externally created offline files will be handled via file upload, similar to the XUL client.

==== Storing Local Preferences ====

=== I need to store local preferences (workstation, grid layout, other UI preferences) outside of the browser in a shared location ===

== You need Hatch ==

  * Do this to persist preferences across multiple browsers
  * Do this to prevent tampering with preferences or the workstation name by staff via the browser developer tools. 
    * Note: you can also do this by disabling access to the developer tools through browser configuration. (e.g. [[https://support.google.com/chrome/a/answer/2657289?hl=en|Chrome User Policies]])

=== I'm fine storing all preferences directly in the browser ===

== You do NOT need hatch ==

  * The browser's local storage will be used.
