Do not leave a WSPL printer running unattended if it has previously overheated. Thermal runaway can cause a fire, especially in retail back offices.
Microsoft has announced an for third-party printer drivers. Starting January 15, 2026 , new third-party drivers for Windows 11 and Windows Server 2025 will only be signed on a case-by-case basis. Users should check with manufacturers like Wasp Barcode or HotLabel for updated, compatible software.

Master Guide to WSPL Printer Driver Configuration: Fixing "Hot" Issues and Optimizing Thermal Print Performance Do not leave a WSPL printer running unattended
The WSPL (Wasp Printer Language) driver acts as a translator between your computer and the printer's thermal head. Using an outdated driver can lead to "hot" errors—where the printer misinterprets commands, causing overheating, jagged barcodes, or skipped labels.
WSPL fixed the driver; now fix the script.

The WPL driver package covers a wide range of desktop and industrial printers, including: WPL-205, WPL-305, and WPL-308. Industrial Series: WPL-606, WPL-610, and WPL-644.
Instead of using the printer's internal hardware to process a print job, a WSPL driver forces your computer’s CPU to do the heavy lifting. The computer translates the document into a graphical bitmap and sends it directly to the printer. While this keeps the retail cost of the printer low, it means any glitch in the driver can instantly hijack your computer's processing power. Why the WSPL Driver Runs "Hot" (High CPU & Spooler Loops)
