How can we help?

Opening CUPS:

To configure the settings for the printer itself, open Chrome and enter the following:

http://localhost:631/printers/

If you get the screen below, you need to enable CUPS for your OS. If not, skip down below to the Localhost Configuration section:

To enable CUPS for your computer, first highlight and copy: cupsctl WebInterface=yes

Next, click the magnifying glass Search icon in the upper right and enter Terminal, then click to run the application.

After Terminal opens, you will see a cursor flashing: paste what you copied and click Return to run the setting.

You can close Terminal after it completes the setting. You will now be able to access your printer configuration from the localhost.

Localhost Configuration

You will see a list of all active printers once the localhost opens. Click on the Printer and a page will load showing the printer attributes.

Find the drop list pictured below and click on Set Default Options.

Under the General tab:

Select Custom Size from the Media Size drop list and enter either 1 x 1 in inches for the 30332 labels, 2.125 x 1.125 in inches for the 30334 labels, 2 x .75 inches for the 30330 labels, 2 x 0.5 in inches for the 1 up labels, or 3.5 x 0.5 in inches for the Rat Tail/Long Tail Labels.

Under the Printer Settings tab:

Darkness: 15

Print Rate: 5 in/sec

Label Top: 0

Print Mode: Tear-off

Tear-off Adjust Position: 0

Reprint After Error: Never

Creating a Custom Label in the System Dialog Window:

Once CUPS is taken care of, on Rain POS select a label to print. Then in Chrome, click on the More Settings and click on the Print Using System Dialog options.

Once in the screen click on the View Details options (If you cannot see more information).

• Click on Paper Size > Manage Custom Labels
  • Click on the + button (Note: Double click on the work “Untitled” can let you rename the label)
  • Set the paper size to correct size needed (example is Long Tail)
  • Non-Printable Area: User Defined
    • Top: 0
    • Left: 0
    • Bottom: 0
    • Right: 0
  • Once all set click on ok.

• Make sure Orientation set to Portrait
• Scale is 100%
• Layout:
  • Reverse Page Orientation is checked

  • Scale to fit paper size is unchecked
• Cover Page:

  • Resolution: 203 dpi
  • Media Tracking: non-continuous (web sensing)

• Once all the settings have been set. Click on the drop down for Presets and click on Save Current Settings and Preset. I would recommend naming this after the label size.

Setting Up the Print Preview on Chrome to be the System Dialog Window:

Enable Setting:

Open up the terminal window and enter the following command:

defaults write com.google.Chrome DisablePrintPreview -bool true

(Note: Found this is the best option to print)

Disable Setting:

Open up the terminal window and enter the following command:

If Disabled, To print correctly use the print using System Dialog Option at the bottom of Print Preview.
