WSD (Web Services for Devices) printers

Many modern printers (especially HP and Kyocera) automatically install using WSD ports, which cause cause inconsistent or incorrect printing behavior in Sage.

To check if the printer is using WSD:

1. Click the Windows Start button, and in the search field, search for Printers & scanners.
2. Select Printers & scanners.
3. Click the printer and then select Printer properties.
4. Select the Ports tab and review the selected port. If it begins with WSD, the printer is using WSD.

If the printer is using a WSD port:

• Reinstall or reconfigure the printer using a standard TCP/IP port
• Use the manufacturer's driver, not the default Windows install
