Use Star CloudPRNT

Star CloudPRNT is a protocol that can print from a remote server.

In order to use Star CloudPRNT, it is necessary to prepare a server that conforms to the Star CloudPRNT protocol. For details about the construction of a Star CloudPRNT server, refer to Star CloudPRNT Protocol Developer’s Guide.


This section explains the printer-side settings that are necessary in order to use Star CloudPRNT with TSP100IV SK.

Setup procedure

Setup is performed from the printer settings screen (Web Configuration).
On the settings screen, it is necessary to save each of the setting items individually.

Depending on the usage environment, it may be necessary to set (change) the DNS servers. Perform this procedure separately. Advanced Settings (LAN):Setting DNS

4. If the CloudPRNT server uses HTTPS/MQTTS, check the security settings

  • From the menu or the menu button at the upper left of the screen, open [CloudPRNT] .
  • Select the HTTPS trust level according to the CA-Certificate that is used.
    When setting a custom CA-Certificate, file upload will be performed in Step 6.
  • To specify the specific server for NTP Server , select “Use custom NTP server” and enter the URL of the server to use.
  • Specify the TLS1.2 Cipher Suites Encryption Level (printer's cipher suite encryption level) according to the support conditions of the server where loudPRNT will operate.
    When this item is set to “MEDIUM”, it may be possible to shorten the time before printing starts.
    For a list of cipher suites supported by each level, refer to Cipher Suite Support List.
  • Enable/disable TLS1.3.
    When this item is set to “DISABLE”, it may be possible to shorten the time before printing starts.
    For a list of supported cipher suites, refer to Cipher Suite Support List.
  • Tap [Submit] .

Note

  • When changing the TLS1.2 Cipher Suites Encryption Level or TLS1.3 setting, consider the setting change carefully in advance because doing so will lower the security level from the initial settings.

    • A screen where you can check and save the entered details will appear.

    5. Save the settings to the printer

    • From the menu or the menu button at the upper left of the screen, open [Save], select SaveRestart device and tap [Execute] .
