Hi,

Using thermal printer, black dots are coming in the page, but it is printing very clearly in the laser printer.
I am attaching the sample image printed.
Is there any way to resolve these print issues?

Thanks,

Tarun:

Without looking at the logs, my first suggestion is to turn off dithering in the printer driver settings:

Control Panel > Devices and Printers > Label Printer > Printing Preferences > Dithering Tab > "None"

The photo results, however, look to be affecting the entire width of the label; dithering spots are usually concentrated around black shapes in the print results.

This seems like either there is some issue with the hardware; if it is a transfer printer, check that the black ribbon is routed properly, and if it is a direct thermal printer, make sure the rollers are clean.

Please attempt a test-print with the operating system - if the results are the same, it is not an issue with QZ-Tray, but rather an issue with the printer itself.

If you wish to get further assistance, please provide logs:

Click QZ-Tray > Advanced > Diagnostic > Zip Logs to Desktop, attach in email; you may send these directly to lite.m.fi...@gmail.com if you do not wish to share this information with the qz-print google group.

Kind regards,
