Lookin 4 printer ex-pert!

profcooksez

I was able to pick up a Verifone 3750 cheap!  Now my thought was to use USB connect to get to low lever printing.  At the binary level I could send code to it to print for debugging  Or locate a printer driver and go with a straight up thermal printer.  Trying first with my PC and then the PI

  • Hello.

     

    Maybe I am. The point is to know what is the printer protocol. I suppose (as Zebra and many others) as suggested by ESC/POS or some custom protocol derived from it.

     

    From where you should print ? I have developed drivers for this protocol on Android, Linux and on Windows there are a couple of tricks.

     

    Always agreeing with Cris, why don't use a small thermal ESC/POS printer (chinese makes them very reliable) ? In the meantime take a look to this old post and let me know if this is something helpful then I think I can help you with some more details: Meditech phase 0 - Annex III: The bluetooth printing protocol

     

    Remember that the important thing is that you see what is the printing protocol of this device or try it with a couple of tricks to see what it is.

  • Good luck You are going to have to hack the printer it would be most likely be a nightmare you will need to get inside the thing.. I just looked at the product manual The RS232 is for a customer keyboard it has limited use. why didnt you just get a printer?

    Do you want to use it in a store? I have 2 VeriFone printers, and they are more of a PIA than they're worth. I put them back in the box and I will sell them.. Personally, I use several printers: Brother QL-700 for tags, Zebra/Fedex/UPS label printer I also have a hp Office Laser (all.in.one) and my hp 7520 color printer which is on the network but used one a month?

    Now If you, after all, this are still wanting to try.

    Get out your tools and open it up.. HACK IT.

  • It looks like the Verifone comes with many interfaces built-in.

    The RS-232 interface appears to be able to perform diagnostics - probably able to print whatever you like if you know the protocol. To experiment with it you might just need a USB-to-RS232 adapter module and an appropriate connector.
