After installation:
| Symptom | Likely Cause | Solution |
|---------|--------------|----------|
| Printer prints gibberish | Wrong emulation mode | Set PT330 DIP switches to Epson FX mode |
| TRMDS 5 hangs on print job | Interrupt conflict or wrong driver architecture | Use Generic / Text Only driver as fallback, then install Oki driver |
| Partial print / truncated lines | Serial buffer overflow | Increase buffer size in driver settings (from 1KB to 16KB) |
| “Driver not available” error | TRMDS 5 expects 16-bit driver | Install using NT Virtual DOS Machine (NTVDM) compatibility layer |

The string "trmds 5" does not correspond to any official Oki driver naming convention. Possible explanations:
Recommendation: Ignore the “trmds 5” part and focus on the official Oki driver for your specific model.
The bundled configuration utility is utilitarian rather than elegant. It exposes common settings—paper size, default tray, resolution—and adds a simple diagnostic view showing toner status and basic error logs.
We strongly recommend avoiding third-party "driver download" sites or files labeled with "trmds," as these often contain malware or bloatware.

Critical Note for TRMDS 5: Do NOT use “Plug and Play” or “Microsoft IPP” drivers. You must download the Custom Oki Terminal Driver package. Look for file names like ML320_421_W7.exe or PT330_Trmds5_Driver.zip.
⚠️ Avoid third-party “driver download” sites. They often bundle malware or supply generic text-only drivers that break TRMDS 5 control codes (e.g., for form feeds, barcodes, or continuous forms).
A: Extract the driver files (using 7-Zip) and manually install via “Have Disk”.
