Zebra Websocket Printer Development and Configuration Introduction

Several of the new Zebra Printers now contain firmware allowing them to connect to a Zebra Tomcat servlet hosted on a remote server which can push print jobs to the printer. Each printer opens 2 connections to the servlet over an assigned port (default 8443), a data connection, and a control connection. The servlet uses a websocket protocol to communicate with the printers. The servlet communicates with other applications on the backend through the default Zebra Web services RMI port (11995) such as a CUPs queueing system or a connection reporting servlet such as Zebra’s ZebraWebServicesDeveloperDemo service. Servlet initialization fails if either port is in use at the time of startup as seen in the $CATALINA_HOME/logs/catalina.out log. The $CATALINA_HOME variable is defined either in the /etc/systemd/system/tomcat7.service or /etc/init.d/tomcat7 file.

NOTE: New printers or printers experiencing trouble connecting should be upgraded to the latest firmware revision.  New printers with extensive shelf life or older printers may not have the required firmware loaded for a weblink connection. The zebra printers use the following SSL security for communications to the cloud server.

a) TLS 1.2 protocol which fixes the infamous "heartbleed" flaw.

b) The following ciphers which step down in the following order until available cipher support is announced by the client.

Ciphers :

RFC Cipher Suite Name OpenSSL Name
1) TLS_DHE_RSA_WITH_3DES_EDE_CBC_SHA EDH-RSA-DES-CBC3-SHA
2) TLS_RSA_WITH_AES_256_CBC_SHA AES256-SHA
3) TLS_RSA_WITH_AES_128_CBC_SHA AES128-SHA

c) The certificate is composed of 2048 bit key strength, an industry standard set by the Certification Authority/Browser (CA/B) Forum which is required for certificates which expire after December 31, 2013.

 Download the most current firmware for the printer and use the Zebra MS Windows Setup Utility to transfer the firmware file to the printer.  The setup utility can be downloaded from the following site:

https://www.zebra.com/us/en/products/software/barcode-printers/zebralink/zebra-setup-utility.html

The firmware can be found here:

https://www.zebra.com/us/en/support-downloads.html

NOTE:

  • Java version "1.7.0_21" used on the MES database server.
  • Tomcat version “7.0.73” used on the MES database server.

Tomcat startup file on server MES database server

/usr/local/apache-tomcat-7.0.73/bin/catalina.sh

Configuration files modified on server MES database server

/etc/cups/cupsd.conf - server MES_portal_server_name

Generate a pkcs12 type certificate

  1. openssl genrsa -out server_name.domain_name.com.key 2048
  2. Change server_name.domain_name.com to something like zprinters.new_domain_name.com for new certificates(definitely use the new_domain_name.com domain in the future)
  3. openssl req -new -subj "/C=US/ST=state/L=city/O=company_name/OU=IT Team/emailAddress=admin@domain_name.com/CN=server_name.domain_name.com" -key server_name.domain_name.com.key -out server_name.domain_name.com.csr
  4. Email the certificate file (server_name.domain_name.com.csr file) to softpm@zebra.com
  5. Continue with the next command upon receiving the server_name.domain_name.com.cer back in the email response

openssl pkcs12 -chain -export -in server_name.domain_name.com.cer -inkey server_name.domain_name.com.key -out server_name.domain_name.com.p12 -passout pass:'pkcs12Password' -name tomcat -CAfile ./link_os_sdk/Webservices/v2.11.2800/cert/ZebraCAChain.cer -caname root

Load Zebra Certificate

Load certificate into the java keystore which Tomcat is using on server 42qmes1.42-q.com

  1. mkdir ~/zebra
  2. cd ~/zebra
  3. cp ./link_os_sdk/Webservices/v2.11.2800/cert/ZebraCAChain.cer ~/zebra
  4. Run the following command from ~/zebra_cert or you will get a -keystore syntax error
    1. export JRE_HOME=/usr/java/jdk1.7.0_17/jre
    2. $JRE_HOME/bin/keytool -importcert -file ZebraCAChain.cer -keystore \ "$JRE_HOME/lib/security/cacerts" -alias "ZebraCAChain" -storepass changeit

 

Delete Certificate

The following can be used to delete an existing certificate if ZebraCAChain currently exists from a previous installation:

  1. $JRE_HOME/bin/keytool -delete -alias "ZebraCAChain" -storepass changeit


Check certificate Installation 

NOTE: Installation can be checked with:

  1. $JRE_HOME/bin/keytool -list -keystore $JRE_HOME/lib/security/cacerts -storepass changeit | grep zebracachain
  2. Restart tomcat if already running
  3. sh /usr/local/apache-tomcat-7.0.73/bin/startup.sh
  4. sh /usr/local/apache-tomcat-7.0.73/bin/shutdown.sh

 

  1. cp ~/zebra/server_name.domain_name.com.p12 /usr/local/apache-tomcat-7.0.73/conf
  2. Permissions should be like -rw------- 1 tomcat7 tomcat7

 

 


Install the zebra.war and ZebraWebServicesDeveloperDemo.war Servlets

The zebra.war and ZebraWebServicesDeveloperDemo.war files are found in the Zebra software development kits(SDKs) which can be located at the site:

Set Up Printer Queues

The parameter "-o printer-error-policy=retry-job” is set for the remote Zebra cloud-connect printer queues. The defaults and current settings are “-o JobRetryInterval=30” (seconds) and the “-o JobRetryLimit=5” (attempts) to word around the hibernation/sleep/suspend mode or initial failures. The default error policy is normally “ErrorPolicy abort-job” in the /etc/cups/cupsd.conf file, which was the reason for no retries during the initial demonstrations. The JobRetryLimit can be increased up to INT_MAX(2^31-1), integer 2147483647, if necessary. There is no infinite setting for JobRetryLimit.

for the linux installation kit to run the WebservicesDeveloperDemo locally like the one at:  http://weblink.cloudapp.net/, load the ZebraWebServicesDeveloperDemo.

Run https://server_name.domain_name.com:port_no/ZebraWebServicesDeveloperDemo The WebservicesDeveloperDemo code can be used to see if the printer is achieving a connection to the servlet on the 42Q server.

NOTE:

  • The SDK is supported on the following devices: PC operating systems using Java Runtime Environment (JRE) v1.6 and 1.7 My testing so far has shown that Java 1.8 seems to work as well for both Tomcat 7 and the Zebra SDK code.
  • Zebra cloud connect does NOT currently support Tomcat8!

Zebra Printer Setup Information for Cloud-Connect Software

NOTE:  Note that new printers or printers experiencing trouble connecting should be upgraded to the latest firmware revision. New printers with extensive shelf life or older printers may not have the required firmware loaded for a weblink connection. Download the most current appropriate firmware for the printer and use the Zebra MS Windows Setup Utility to transfer the firmware file to the printer.

The "value" string can be translated as follows:

EST5 (Eastern Standard Time; 5 hours off UTC), EDT4 (Eastern Daylight Time; 4 hours off UTC), running from 2AM (/02; fully qualified: /02:00:00) from the second Sunday in March (M3.2.0/02) through 2AM (/02; fully qualified: /02:00:00) on the first Sunday in November (M11.1.0/02). M indicates the Month follows, followed by the two-digit month, the week (1 is the first week in which the specified weekday occurs, and 5 indicates the last week of the month with that weekday) and the weekday (0 is Sunday). The time starts with a slash, and unspecified trailing fields default to zero.
