MF ticketing uses continuous labels, so proper setup is important to avoid issues like continuous feeding, misalignment, or incorrect label sizing.
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.
Install QZ Tray
Open it and make sure it is running in the menu bar (top right)
Refresh AccelerList after opening
👉 If QZ Tray is not running, printing will not work
To guide you about QZ Tray, kindly click the icon below:
2. Open AccelerList in Chrome (Recommended)
Close the AccelerList desktop app (if open)
Open Google Chrome
Log in to AccelerList
Using Chrome helps ensure proper communication with QZ Tray.
3. Open Printer Settings in AccelerList
Navigate to:
Settings → Printer → MF Ticketing
4. Configure Printer Settings in AccelerList
Set the following:
Active Printer: Brother QL-800 / QL-700
Printer Driver Config: Select available Brother config
Orientation: Portrait
Label Type: Dymo 30270 (Continuous)
✅ Click Save Changes
5. Set Printer as Default (Mac)
Go to System Settings → Printers & Scanners
Select your Brother printer
Set it as the default printer
This helps AccelerList and QZ Tray detect the correct printer.
6. Enable CUPS Web Interface
Open Terminal
Enter:
sudo cupsctl WebInterface=yes
Press Enter
Enter your Mac password if prompted
7. Configure Continuous Label in CUPS (Important)
Open your browser
Go to: http://localhost:631
Click Printers
Select your Brother printer
Then:
Click Administration
Select Set Default Options
Set:
Media Size / Paper Size: Match Dymo 30270 (or equivalent continuous size)
Media Type: Labels
Enable Continuous / Continuous Feed / Continuous Wide
⚠️ Important:
This must be set in CUPS, not in regular printer preferences
Incorrect setup may cause:
Continuous feeding
Misaligned labels
Printing issues
8. Connect AccelerList to QZ Tray
In AccelerList, open printer settings
Select your printer
When prompted, click Allow / Trust
9. Print a Test Label
Click Print Test Label in AccelerList
Confirm:
Labels stop correctly
Alignment is correct
No continuous feed issues
10. Troubleshooting (If Test Print Fails)
If printing does not work:
Restart QZ Tray and refresh AccelerList
Confirm printer is still set as default
Recheck CUPS settings (continuous enabled)
Restart your Mac if needed
Quick Reminder ✅
For best results:
Use Dymo 30270 continuous labels (or matching size)
Enable Continuous Label in CUPS (not printer preferences)
Ensure QZ Tray is running
Use Google Chrome
Set printer as default
