Since MF ticketing uses specific label formats, it’s important that both your Mac printer settings (CUPS) and AccelerList settings are properly aligned to avoid printing issues.
1. Download and Install QZ Tray, then Open Printer Settings in AccelerList
First, make sure you download and install QZ Tray.
Then navigate to:
Settings → Printer → MF Location Tickets
2. Configure Your Printer Settings in AccelerList
Make sure your settings match the recommended configuration below:
Active Printer: Rollo Printer
Orientation: Landscape
✅ Click Save Changes
3. Supported Label Types for MF Ticketing
We support the following label types:
30270 Continuous Labels
4x6 (UPS Labels) — as long as properly calibrated
⚠️ Using unsupported label sizes may result in:
Misaligned prints
Incorrect formatting
Printing errors
4. Configure Printer Settings via CUPS (Mac)
If labels are missing, misaligned, or not printing correctly, configure your printer using CUPS:
Open CUPS:
Open Safari or Chrome
Go to:
http://localhost:631
If it doesn’t load:
Open Terminal
Run:
sudo cupsctl WebInterface=yes
Configure Your Printer:
Click Printers
Select your Rollo printer
Click Administration → Set Default Options
Set the following:
Media Size / Paper Size: Match your label (30270 or 4x6)
Orientation: Landscape
⚠️ IMPORTANT (For Continuous Labels):
If you are using 30270 continuous labels, make sure to:
Enable Continuous Wide under CUPS settings
This ensures proper alignment and continuous printing behavior.
5. Print a Test Label in AccelerList
Go back to AccelerList
Click Print Test Label
Confirm:
Proper alignment
Correct size
Clear output
Quick Reminder ✅
For best results:
Use 30270 Continuous Labels or 4x6 labels
Enable Continuous Wide in CUPS (for continuous labels)
Ensure labels are properly calibrated
Keep orientation set to Landscape
Make sure CUPS and AccelerList settings match
Install and run QZ Tray
If everything is set correctly, your MF Location Tickets should print cleanly and consistently on Mac OS 👍
