Following these steps ensures your labels print clearly, align correctly, and avoid common printing issues.
1. Install and Run QZ Tray (Required)
Before setting up your printer, make sure QZ Tray is installed and running.
QZ Tray is required for AccelerList to communicate with your printer.
Download and install QZ Tray
Open QZ Tray
Confirm it is running in the system tray (bottom-right corner)
👉 If QZ Tray is not running, printing will not work
2. Open AccelerList in Chrome (Recommended)
Close the AccelerList desktop app (if open)
Open Google Chrome
Log in to AccelerList
Using Chrome ensures better communication with QZ Tray.
3. Confirm Your Printer Works in Windows
Before connecting to AccelerList:
Go to Control Panel → Devices and Printers
Right-click your Zebra printer → Printer Properties
Click Print Test Page
✅ Only proceed if the printer prints successfully
4. Open Printer Settings in AccelerList
Navigate to:
Settings → Printer → SKU + FNSKU Labels
5. Configure Printer Settings in AccelerList
Set the following:
Active Printer: Zebra Printer
Printer Driver Config: Zebra 203dpi
Orientation: Portrait (or depending on label)
Label Type:
30334 — 2 1/4" x 1 1/4"
30336 — 1" x 2-1/8"
30252 — 1-1/8" x 3-1/2"
Or any label that matches these dimensions
✅ Click Save Changes
6. Set Printer as Default (Windows)
Go to Devices and Printers
Right-click your Zebra printer
Click Set as Default Printer
This helps AccelerList detect the correct printer.
7. Configure Printer Preferences
Right-click your printer → Printing Preferences
Set the following:
Resolution: 203 dpi (recommended for Zebra)
Paper Size: Match your selected label (30334, 30336, or 30252)
Orientation: Match AccelerList setting
⚠️ Make sure:
Label size matches your physical labels
Avoid using unsupported/custom sizes unless necessary
8. Allow AccelerList in QZ Tray
Open QZ Tray from the system tray
Click Site Manager
Ensure AccelerList is marked as Allowed / Trusted
9. Connect Printer in AccelerList
Select your printer in settings
When prompted, click Allow / Trust
10. Print a Test Label
Click Print Test Label in AccelerList
Confirm:
Label is aligned
Not cut off
Prints clearly
11. Troubleshooting (If Printing Fails)
If labels do not print correctly:
Restart QZ Tray and refresh AccelerList
Confirm printer is still set as default
Recheck label size and driver config
Try another supported label size
Restart your computer if needed
Quick Reminder ✅
