Are you using the standard USB connection, through the driver, or over the network? The S4M has not been tested but it "should" work as long as it is standard with essentially default settings. What error are you getting?
For the LP 2844 - again it should work as long as the printer is set to ZPL and is a standard version of this printer and firmware.
For the issue of printing 2 labels, you likely need to calibrate the printer so it can detect the gaps in your labels. There are many ways to do this but the easiest is likely on a PC -Go to 'Devices and Printers' . Right click the printer and select printing Preferences. Select the Tools tab and Action-> Calibrate media. Then hit Send.
I have tried to use the S4M and LP2844 through usb .
I have tried to use it through the browser print sample screen and there is no specific error i got in screen.
How to check if LP2844 supports zpl or not.
These 2 are with my client. I was checking in his machine.
How 2 get the proper error in browser print. How to set lp2844 to zpl
For checking the LP2844 if it supports ZPL, you can check the printer driver ("Devices and Printers" -> Right click printer -> "Printer Properties" -> General tab -> Model ) or send me the part number from the bottom of the printer.
The model no of LP2844 is part no - 2844-20320-0001
I will carryout further testing with dev demo.
The LP 2844 model no is LP2844. and in the back side the printer it is mentioned that 'EPL' and model is LP2844.
Please also let me know whether S4M can be used for Browser print.
Please provide your resposne
