## Changes Made to editprinter.asp
### Before (Old Style):
```asp
```
### After (Modern):
```asp
```
### Error Handling Improvements:
**Before:**
```asp
Response.Write("Error: Invalid printer ID.
")
Response.Write("Go back")
```
**After:**
```asp
Response.Redirect("displayprinters.asp?error=INVALID_PRINTER_ID")
```
All errors now redirect with error codes:
- `INVALID_PRINTER_ID`
- `INVALID_MODEL_ID`
- `INVALID_MACHINE_ID`
- `FIELD_LENGTH_EXCEEDED`
- `MODEL_REQUIRED`
- `VENDOR_REQUIRED`
- `MODEL_FIELD_LENGTH_EXCEEDED`
- `VENDOR_NAME_REQUIRED`
- `VENDOR_NAME_TOO_LONG`
- `VENDOR_CREATE_FAILED`
- `MODEL_CREATE_FAILED`
- `UPDATE_FAILED`
### Success Handling:
- Redirects to `displayprinter.asp?printerid=X&success=1`
- Falls back to Bootstrap-styled redirect page if meta refresh fails

## Security Features Preserved
✅ **All security features maintained:**
1. Parameterized queries throughout
2. Input validation (numeric checks, length checks)
3. HTML encoding for all output
4. SQL injection prevention
5. XSS prevention
6. Nested entity creation (vendor → model → printer)
