How do you speed up the printing speed on a Paxar 9800/9850?

There is a small shaft on the back panel of the printer, below the red/white dip switch settings. This shaft sas a slot in it. Facing the rear of the printer, turn this shaft clockwise to increase contrast.
Press PAUSE and FEED buttons on front panel AT SAME TIME to print two label test labels. One of these labels will tell you your contrast setting. I wouldn't adjust the contrast any higher than about 75 (about half way) or you're in danger of prematurely blowing your printhead. Printheads are expensive...

Here's a video that shows how to properly load supplies into the gun. It's possible that the supplies aren't loaded properly..

kindly go to its main menu and set the media type direct Thermal. or check your printer properties u can change the media from there to Direct Thermal.

The printer uses thermal direct labels, kind of like fax paper, where no ribbon has to be used.

That said, contact Avery Dennison, the people who purchased Paxar, and tell them that you need supplies for this printer. Their number is 1-800-543-6650. They can help you from there.

Perform an internal diagnostics test print. I believe you can press both of the arrow buttons at the same time, and it should print out what's in the printer and how its configured. There you should find the firmware version.

You have a format problem. Something isn't correct in your mpcl code.
Error 400 - "The character immediately following { is invalid or not an ASCII character."

Are you printing a serial or parallel barcode? If you don't know, a serial barcode looks like a ladder as it prints out on the label. A parallel barcode looks like a picket fence. A serial barcode (ladder) prints at 2.5 ips by default. You can't increase the speed. If you're printing a parallel barcode (picket fence) you must hit "enter' once you adjust the speed setting in the printer menu. If you've done that and it still won't increase speed, then the speed is set by the software itself, and overrides any changes you make in the printer menu. The speed adjustment must then be made in the software, not the printer.

When you're sending data to the printer you're sending a command that is telling the printer you're NOT using a ribbon. When the printer receives the data it's shutting off the ribbon. Check your software.
You should be set for THERMAL TRANSFER.(RIBBON)
THERMAL DIRECT Means NO RIBBON

These types of errors are data errors. If you post your datastream, I may be able to tell you where the error is at.

My brother dcp tells me
unable to print check troubleshooing and maintenance chapters.
I have done this and cleaned the printer, it also tells me ink jets empty, they are all new ones.
Driving me mad any suggestions so I can get my sanity back.

Thanks
