He might need to use a PCL5 driver then.
According to the 'pedia, PCL6 was introduced in 1995: Printer Command Language - Wikipedia, the free encyclopedia
Speaking of the video, it reminds me of something that happened to me just the other day. My workstation's primary monitor, a 30" Dell LCD, had its backlight fail. When the monitor is powered on, you can still see the user interface if you shine a flashlight directly at the screen. I called up Dell to ask about a backlight replacement. Their advice is to discard the monitor and replace it. Even when I asked the technician to confirm that with a manager, he quickly returned with confirmation, claiming the bulb and inverter board simply cannot be replaced without replacing the whole LCD panel. He asked if I would like assistance finding a replacement monitor; to which I responded politely that they are crazy and ended the call.
Obviously discarding this monitor would be ridiculous. To this day, four years after I purchased it, assuming it had a working backlight, it would fetch $700 on eBay.
Calling local repair shops quickly revealed that the replacement bulbs are fairly cheap (less than $50) and even if the inverter board has failed, that's less than $150. Unfortunately, they don't yet sell LED backlight retrofit kits for this size monitor.
