Unpacking the Printer
Upon delivery each box should contain:
1 x Epson TM-T20iii or EpsonTM-T20ii printer
1 x USB type B to USB type A cable
1 power cable
If any components are missing from the box, please contact Eventive support immediately. Please retain the box and all packing materials for return shipping.
NOTE: If your Mac does not have a USB type A port, you will need an adapter (likely USB type A to USB C). Adapters are not provided by Eventive. Examples of USB type A to USB C Adapters are shown in the image below.
NOTE: Rental printers from Eventive do not come with ticket stock or thermal receipt paper, you will need to source this independently.
Connecting the Printer
Plug the printer’s power cable and USB cable into the back of the device, and then into your power source and Mac computer.
Locate the power switch on the front of the unit and turn the device on. A blue light will appear on the top of the printer to indicate that it is on.
Once the printer is powered on, the computer may ask if you would like to “Allow accessory to connect?”, click “Allow”.
Your computer may not automatically detect this device as a printer. Proceed to download and install the Advanced Printer Driver.
NOTE: These instructions are for a computer running on MacOS 15.3. Instructions for earlier versions of Windows may vary slightly.

Test Print a Ticket
After the printer driver is installed and you have printed a test page, try printing a ticket.
Go to the box office and issue yourself a ticket to print. Alternatively, you can locate any ticket on a customer account and click “Download” to the top right of the ticket table on the customer account to print the ticket.
Print the ticket:
In Chrome, click the printer shaped “Print” icon in the top right corner of page to open the print dialog box.
In Safari, click the File Menu followed by Print to open the print dialog box.
In the print dialog, be sure that the Epson TM-T20iii printer is selected as the destination and choose the closest available paper size.
Click “Print”.
In all likelihood, your first ticket will be long and you may need to configure a custom paper size.
Adjusting Settings
NOTE: The following steps are the same for both Epson TM-T20iii and Epson TM-T20ii printers.
If your test ticket was too long, you’ll need to create a user defined paper.
Configuring the Paper Size in Safari
When printing a ticket, in the print dialog, click on the “Paper Size” drop down menu.
In the Paper Size drop down menu, select “Manage Custom Sizes…”
Click “+” in the bottom left corner of the Paper Size dialog box to create a new custom paper size.
Double click on ‘Untitled” in the left side of the Paper Size dialog box to name your new paper size. In this example, we have renamed the paper to “2.5” x 6” Ticket”.
Specify the dimensions and margins for the new paper size. In the above example, we specified a width of 64mm by 153mm with 0mm margins all around. Depending on the native unit of measurement specified for your computer, you may need to specify width in either mm or inches.
Click OK to save the settings.
Print a test ticket.
If you are not satisfied with the dimensions of the test ticket, adjust the paper size settings until you achieve the desired output.
Configuring the Paper Size in Chrome
When printing a ticket, in the print dialog, click “Print using system dialog…”
In the system print dialog, click on the “Paper Size” drop down menu.

Print a test ticket.
If you are not satisfied with the dimensions of the test ticket, adjust the paper size settings until you achieve the desired output.
Once you have configured a custom paper size you are satisfied with, you select that paper size in the Print dialog box in Chrome rather than printing from the system dialog each time.
Once you have connected the printer to your computer and applied any desired settings, you will be ready to print tickets!
