Create Custom Labels in Canix

1. Navigate to Tags & Labels > Print Labels > Custom

2. Select a Tag Type (Package, Plant, Plant Batch or Non-Cannabis Lot) and a sample Tag to work with:

3. From the "Available Fields" menu, select the fields you need to have represented on your labels, including barcodes, item names, strains, address, license #, etc.

• Take care to leave space between the edge of the labels and all fields, images, barcodes, etc. This will help ensure nothing gets cut off during printing.
• The "Default Test Fields" pull the most recent Metrc Test Result if available, then Confident Cannabis if available, then Manually uploaded results.
• To adjust the auto-generated field sizes, positions, or rotation, select the text in the label preview and use the controls above the label (+, -, or rotating icon).
  • Text size is 8pt font by default. To resize the text size, use the +/- button above the label preview to increase/decrease the text size.
  • Each increase/decrease changes the font size by 1 pixel (~0.5 pt changes in font size)
  • To reach 6pt font, the text size can be decreased 6 times (select the - button 6 times)
• To adjust the # of decimals applied to quantity and lab test result fields, use the decimal icons after selecting a field:
  • Decimals can be adjusted for most numeric fields with the exception of:
    • Preferred THC
    • Preferred CBD
    • Top Three Terpenes
    • Net Weight
    • Net Weight (Metrc/US)
    • To request decimal adjustments for any of the above fields please upvote this post and leave a comment with the specific fields you need updated.
• Tip: Don't see details for an auto-generated field populate? Check the package or plant tag in the Active Packages report or Plant reporting to verify that information is in Canix.

4. Use Free Text fields to add additional information to your template, for example state-specific warnings:

5. Add your company logo and or state warning symbols as images as needed:

• As of March 28th, 2025 multiple custom images are now supported on Canix, allowing for Warning Symbols, Branding, Phenotype Indicators, QR Codes and more:
  • 
  • To use multiple custom images, simply upload multiple files and select on the left-side image panel. Selected images will be indicated with a green check mark:
    • 

6. Use "Save As" to save a new template, or "Save" to save changes to an existing template:

Download Labels from Canix

There are two options for generating labels in Canix, either by tag sequence for example tags 100001-100030, or by selecting Packages, Plants, Plant Batches from the inventory tables and selecting "Print Labels".

Download Labels by Tag Sequence

Use this approach when generating tags for inventory that is yet to be packaged or planted, and created in Canix.

1. Select a Template and Tag Type
2. Start typing in the tag field to begin searching for a tag number and select from the results, or copy and paste a tag number into this field. Click on the tag number in the dropdown to load the field data and activate the Available Fields box and Print button.
   • Note: If printing more than 1 label, the ending tag number will be displayed below the tag field.
3. If printing more than 1 tag number, enter the number of tags to generate in a sequence in the "# of Labels" field.
4. Select Print/Download in the top right to see a preview and apply settings:
   • File Format (PDF vs ZPL)
   • Color vs Black/White
   • # of Rows Per Page and Labels Per Row
   • Vertical/Horizontal Offsets

Download Labels for Specific Inventory

Use this approach when downloading labels for specific inventory, where the tag #s may not be in sequence.

1. Navigate to your the inventory table you need to download labels for, for example the Packages table.

2. Select the Packages to download labels for, and select "Print Labels" from the Actions menu:

3. Select a Template

4. Select Print/Download in the top right to see a preview and apply settings:

• File Format (PDF vs ZPL)
• Color vs Black/White
• # of Rows Per Page and Labels Per Row
• Vertical/Horizontal Offsets

Printing PDFs from Canix

Printing via PDFs

As long as your printer can print PDFs, your printer will be compatible with Canix. To print PDFs:

1. Check that the size of your template exactly matches the size of your physical labels.

2. Download the PDFs from Canix

3. Open your PDF in Preview (Mac users) or Adobe (Windows users)

• For the Adobe Reader Free Version download here. Preview comes pre-installed on Macs.

4. Set the Page Size in Preview or Adobe to exactly match the size of your label/label sheet.

 

5. Set the scale in Preview/Adobe to 100% of size

6. Print!

If your prints are blank, fuzzy, or the sizing is incorrect after taking the above steps, try the following to debug further:
 

1. Delete "QZ Tray.app" by searching in your apps folder.
2. Delete current printer drivers:
   • On Mac:
     • Start Finder
        
     • On the menu bar select "Go" > "Go to Folder"
       • 
     • Enter "/Library/Printers/PPDs/Contents/Resources/"
     • Delete old and un-needed drivers.
        
   • On Windows:
      
     • Open Start and select "Settings > Devices > Printers and Scanners"
     • Under "Related settings", select "Print Server Properties"
        
       • 
     • Select the "Drivers" tab
     • In the list of installed drivers, select the printer driver and click "Remove"
       • 
     • Select "Remove driver and package", and click Ok
     • If you get a confirmation prompt to "Remove Driver Package", click "Delete"
3. Remove your Printer from your computer
    
   • On Mac:
      
     • Select the Apple Menu
     • Go to "System Preferences"
        
     • Select "Printers & Scanners"
     • Select your Printer and remove by clicking the "-" symbol in the bottom left
   • On Windows:
     • Open Start and select "Settings > Devices > Printers and Scanners"
     • Select the printer to remove and delete it
4. Restart your computer
    
5. Download and install the printer driver recommended by the manufacturer (for Zebra Printers you can search your model to find drivers from this page)
   • If the driver installation asks you to add a printer, select your printer at this step.
6. If the driver installation does not allow adding a printer, navigate back to "Printers & Scanners" in your setting and add your printer back to your laptop
    
7. If using a Zebra printer, you should also update your "Dithering" settings to "Clip Art" or "None".
   • To find your dithering settings navigate to Start > Printers & Scanners > Select Printer > Manage > Printing Preferences > Graphics.
8. Re-test printing a PDF with your new setup

Printing via PDFs for Zebra Printers

As of the March 2024 release, Canix will no longer send print commands directly to Zebra printers. All printing will be done by:

1. Downloading the Labels PDF
2. Printing the PDF from Preview (for Mac Users) or Adobe Reader (for Windows users)

You can expect sprint speeds to be faster printing form Preview or Adobe Reader as compared to Canix' previous solution, QZ Tray. If you have QZ Tray installed on your machine, we recommend uninstalling this from your computer immediately.

What happens if my Zebra Printer does not support PDF printing?

Almost all Zebra printers are installed with PDF Direct that enable printing PDFs, although it is possible that some older Zebra models will not have the necessary software. To get this software installed on your Zebra printer please reach out to Zebra support for assistance at +1-877-275-9327.

Let them know that:

• You need to print PDFs with your Zebra printer via PDF Direct
• The model of your printer

Zebra support will talk you through the specific steps required to update your make and model to support printing PDFs.

Installing QZ Tray

If direct printing is enabled in your account, you'll need to install QZ Tray to take advantage of this feature. Please keep in mind that QZ Tray Support is a 3rd Party app that some customers have reported bugs for in the past. Canix will not be able to fix issues with QZ Tray.

To install QZ Tray follow these guides:

1. Initial Install
2. Setting up Zebra Printers with QZ Tray

Troubleshooting Common Issues

Why is my printer turning off in the middle of a print job?

Certain printers, in particular thermal printers such as Zebra printers can overheat during printing. One way to prevent this is by reducing the speed of your printer. This can be adjusted in Printer Settings which may be access through the screen on the printer itself or through a program like ZebraDesigner.

Why is the PDF I downloaded not lining up with my physical labels?

Please see Printing via PDFs. To ensure your PDF aligns with your labels, you'll need to specify the exact size of your labels in Canix and use scale = 100% when printing from Adobe or Preview.

Why is my print quality lower for smaller labels?

Lower print quality could be caused by your printer's setting our missing firmware on your printer. To trouble-shoot, take the following steps:

1. If using a Zebra printer, update your "Dithering" settings to "Clip Art" or "None". This will increase the definition of your image.

• To find your dithering settings navigate to Start > Printers & Scanners > Select Printer > Manage > Printing Preferences > Graphics.

2. Update the darkness setting for your printer. Darker images typically result in higher definition and an increase in quality. See instructions for Zebra printers here.

3. Lowering your print speed can give more time for a thermal printer to mark the label and lead to higher quality definition. Print speeds can be adjusted in Printer Settings which may be access through the screen on the printer itself or through a program like ZebraDesigner.

4. Increase the size of fonts on your label. The larger the font-sizes, the more clearly they'll print on the label.

5. Certain Zebra printers do not have PDF printing firmware installed by default. To activate PDF Direct for Zebra printers see these instructions. Start with step 5 and if that fails (it's possible PDF Direct is installed on your machine but not activated). If step 5 does not result in the desired quality start back from step 1.

6. Consider if you have the right equipment for the job. Higher DPI printers will result in finer resolution, for small Pre-Roll labels for example, the Zebra ZD421 300dpi performs significantly better than the Zebra ZD421 203dpi.
