RocketShipIt Thermal Print Server

Printing shipping labels has never been easier


HeartBeat Sensor

Periodically pings a URL of your choice indicating live printers available from pool.

Webhook Integration

Sends HTTP POST request with valuable data back to a URL of your choice, useful for monitoring all printers from a central location

HTTPS Support

Run server in secure mode or use CORS to enable printing from SSL secured pages


Ability to automatically print without user interaction (no clicking of a print button) and set up queues.

Remote Configuration

If configured, it can be called from remote computers or across the internet via HTTPS

Multiple Print Stations

Ability to have multiple shipping stations configured and distribute load across workstations.

Multiple Labels

Send one or multiple labels in a single request

Cross Compatible

Works great with Windows, Mac, Linux, and ARM via Raspberry Pi

ZPL or Graphic Labels

Send thermal ZPL print codes or a gif/png graphic. We will automatically convert, resize, and rotate images to be thermal compatible


Thermal printers require their own special print codes which need to be sent to the printer unaltered. Most web browsers do not support this for security reasons.

We created a special print server which will allow you to easily send thermal labels direct to your Zebra or Eltron thermal printer.


<form method="post" action="http://localhost:8080">
        <input type="hidden" name="label" value="<?php echo $base64Label; ?>" />
        <input type="submit" value="Print" />

Print pack slips easily

Just send a simple JSON request to /packlist to print out a pack slip along with your shipping label.
