Re: Zebra LP 2844 parallel communication problem
The printer is installed on the PC using a specific port. If it's installed on the USB port, it won't work on the parallel port. Do you have this printer installed 3 different times? Need more details such as how was it installed the first time? And if it's working on the other 2 ports, why does it have to work on the parallel?

You need to buy the zebranet PS2 print server
P/N G46692 External PrintServer II. It will plug into the parallel port. they just stoped making them but they are still for sale at zebra resellers. here is one at random from google
The ^default command has been added to the EPL2 commands, starting in
firmware version 4.39. This command will set the printer back to factory
settings as long as the printer is in page mode. The command is not supported in
line mode at this time. The command is case sensitive. Syntax: ^default.
You can send the command to the printer via the parallel or serial port. Parallel:
Open command prompt (DOS prompt) See windows instructions for details.
At the prompt type: ECHO ^default>LPT1 <enter> Serial:
Assuming standard communications on the printer of Baud 9600, No parity, 8
bits, 1 stop bit and use of COM 1:
At the prompt type: Mode Com1:9600,n,8,1 <enter> ECHO ^default>COM1 <enter>
I find that a lot of serial to usb or parallel to usb converters do not work due to the fact you can't get bidirectional communication. In every case I have dealt with, the resolution was a dedicated port card to physically install a parallel or serial port in the system.
You need a piece of software to create a Virtual com port, make sure you have the comms set correctly 9600, n, 8, 1 and print to that port, you will find it clearly marked in Device Manager. You can get a parallel to USB cable then you can use your driver set to LPT1
If you are using CAL (Create A Label) you must have a device called a "Dongle" plugged into your parallel (or USB) port. This acts as the activation key for CAL. If there is no dongle then CAL only works in demo mode. That's why printer Icon stays grayed out. The "Dongle" normally plugs directly into the parallel port and one end of the parallel lead plugs into the "Dongle" while the other plugs into your printer.
I would suggest that you download "Zebra Designer" software from the Zebra Website..This will work without any activation. If you use ZD you must use the correct ZDesigner driver. (Install automatically as part of ZD setup) This driver only works with ZD.
If you need to link to a database then you will have to BUY label software. Zebra Designer Pro, or Nicelabel, or Bartender....etc.
