Send hex commands to printer

[dotkpay]

Hello,

I have been trying to configure a receipt printer, model BTP-R880NP so as to have a center aligned receipt with small margins, but am informed I have to send hex commands to the printer.
How do I send these commands from a web page printing a receipt to the USB printer?

Thanks in advance

I think that you have to make these settings on the printer itself. Take a look at APPENDIX A here: http://www.orient-technologies.com/brochures/BTP-R880NP%20Users%20%20Manual%20V1.0.pdf

You might also need to change the settings in the control panel for that printer.

Thanks Dwarf, I have looked through the pdf you linked to before together with the programming manual of the printer. But they don't specify where exactly I should insert the hex code.
For example the statement 1D 4C nL nH sets the left margin but how do I run it exactly.

Dotkpay, welcome to the windows 7 forum.

The best way to send Hex codes to a printer is to create a text file and then copy it to the printer port.
One way is to create from the keyboard the ascii codes by using the alt+number pad to create a file.

from the command prompt.

copy con code.txt
press the alt key and the numberical equivelant for the hex code
when you have finished create the file Press the function key 6 which sends
a control Z (end of file) to the new file you created and closes the file.

then all you have to do is to copy filename lpt1: or whatever the printer port
is.
I have send a page eject to the printer by the following.
copy con lpt1:
ALT+12 then control Z (or f6)
and the page ejects..

I hope this helps.
