HP is pleased to announce the release of version 1.3.0 of the Link for Device SDK.

In August of last year HP announced the Developers Release of JetAdvantage Link for Device SDK on the Developer’s Portal, providing developers powerful and simpler ways to create print and scan integrations for end-users. We are excited to add even more capabilities on our platform in our latest release, JetAdvantage Link for Device SDK version 1.3.0 (associated with the release of FutureSmart Bundle 4.8.0.1 device firmware).

Link for Device SDK (version 1.3.0):

Please note: A device firmware upgrade to FutureSmart Bundle 4.8.0.1 is required to use this SDK. An announcement will be made when the firmware is available on hp.com. In the meantime, the firmware has been made temporarily available for download from the SDK Download page.

Download the new SDK from the Download page.

 
Major new features of this version include:

• Official Support of recently introduced Devices (some require a 2GB DIMM accessory). See the updated Compatible Devices page for details.
• (App) Attestation API and the HP Token Proxy – Eliminate OAuth Client Secrets from your apps by managing your Client Credentials in HP’s cloud and using HP’s Token Proxy (See how here)
• (USB) Accessory API – Apps can now read from and write to USB (HID Class) Accessories, including authentication card readers (See AccessoryOverview.pdf)
• Copy API – Create, Store, Enumerate, Release, and Delete Stored Copy Jobs (See CopySampleOverview.pdf)
• Mass Storage API – Listen for Mass Storage events and read/write to Mass Storage (See MassStorageOverview.pdf)

New/Enhanced Sample Apps:

• New AttestationSample – Demonstrates use of the HP Token Proxy
• New AccessorySample – Demonstrates basic USB accessory usage
• New AccessoryAgentSample – Demonstrates use of a USB card reader accessory for Authentication
• New CopySample – Demonstrates how to perform Copy and Stored Copy functions
• New EmailSample – Demonstrates how to send email using either the printer’s SMTP or custom SMTP settings
• New LauncherSample – Demonstrates how to create a “Kiosk Mode” (a.k.a. Launcher) App
• New MassStorageSample – Demonstrates how to listen for Mass Storage events and read/write to Mass Storage
• New MultiLanguageSample – Demonstrates sub-activity buttons and multilanguage button labels
• Enhanced Scan and Print Samples – Now include job status
• Enhanced Config Sample – Now includes a default config in the HPK

 
Other notable changes in this release include:

• Platform Versioning

To enable a simple app compatibility check before installation, we have introduced a platform versioning scheme into this SDK and firmware release, of the form {Android API Level}.{Link API Level}. In this first release, the Platform Version is 19.3. Starting on 7/19/2019, all apps uploaded to the App Center will be required to include a minimum platform version declaration in the HPK (See the new HPKTool in this SDK for details).
 

Coming soon:

• The SDK 1.3 device simulator will be available soon.

 
Restrictions:

• [MASSSTORAGE] Size of getFreeSpace() and getTotalSpace() is not correct.

The FutureSmart 4.7.2 firmware release changed the default availability of TLS protocol versions. The updated security profile for FutureSmart version 4.7.2 defaults to:

• TLS 1.2 – Enabled
• TLS 1.0 & TLS 1.1 – Disabled

The new TLS protocol defaults are applied in the following circumstances:

Devices purchased with FutureSmart bundle 4.7.3 and later

• Use the new TLS defaults (TLS 1.0 / 1.1 disabled)

Devices updated to FutureSmart bundle 4.7.2  or later from FutureSmart 3 bundles or FutureSmart 4 bundles before version 4.7.2

• TLS settings are not updated to the new defaults and maintain their current setting.

Performing the following device resets on FutureSmart 4.7.2 or later devices update the TLS  settings to the new defaults, overwriting any previously configured setting

• Format Disk
• Partial Clean
• Cold Reset

Important Note: HP and 3rd party solution software may have a TLS 1.0 dependency requiring TLS 1.0 to be enabled / re-enabled for installation or to function properly after installation.   Details on how to do that can be found in the document here.

Important Note: FutureSmart bundle 4.7.2 is an interim firmware release only available from HP Support.

The following devices will ship with FutureSmart bundle 4.7.3 which have the new TLS defaults.

• HP LaserJet Managed MFP E72525/ 30/35
• HP Color LaserJet Managed E77822/25/30
• HP LaserJet Managed MFP E82540/50/60
• HP Color LaserJet Managed MFP E87640/50/60
