My printer isn't printing the full paper width, what to do?

The default printing width in S&D is set for 58mm printers. Just go to the settings and increase the printer width. See printer settings for common values. Rule of thumb is:

• 58mm: 384
• 80mm: 504 - 576

My printer is randomly stopping half way through printing, what to do?

Try enabling Explicit Initialization and / or Force Standard Mode in the settings and unplugging (not just using the on/off switch) your printer for a few seconds until all LEDs are out between changing the settings.

Windows: Multiple Devices

It was reported that in some cases a printer might be registered twice in the Device Manager. Removing the device should fix problems.

I'm getting a Trojan warning on Windows, what's going on?

This is a false positive triggered by a library that S&D uses. In newer versions of S&D the related component was disabled and trojan warnings should not occur anymore.

I'm getting 'RAW USB Printing' errors, what to do?

If you get errors like Error: printer wasn't able to print: libusb: bad access [code -3] or Error: printer wasn't able to print: not supported [code -12] this can be related to other drivers interfering or S&D not having enough privilege's. You can try:

• Running S&D as Admin (Windows) or sudo (Mac, Linux)
• Switching the USB port and re-selecting it on the Device page
• Try using Direct Printing (Windows) or CUPS (Mac, Linux)

Getting strange libusb errors, what to do?

If you get errors like handle_events: error: libusb: interrupted [code -10] and don't need 'Raw USB Printing' try downloading the gui instead of gui-usb version of S&D.
