BMC international fiscal printer : xharbour

Luiz,

I had copied the file dllcall.c and commented out the line 518, wich
generates the messagebox. It is clear that there is an error, in fact,
calling directly as you suggested I get a GPF.
Now the program is working and the printer too, but there is some
obscure point to solve.
I think the trouble is for returning parameters but I am not sure.

Do you have any suggestion?

Hi Alex,

My situations is under vb, the demo runs I had made, returns the status
and error values from the call, but under xharbour no returns are made.
Is mainly sure that the dll is giving some errors after processing the
commands to the fiscal printer and then return with error. My windows is
in spanish, but seems that some I/O functions are executed in a
overlapped or superposed form.
The manufacturer is not giving help about this point. Just say close all
com ports: I need between 3 to 8! for working with all peripherals.
The other solutions means day of code using direct protocol.
I will investigate with the "modified" dllcall to see if I can obtain a
better work. Unfortunately my c skill are some lower.

Regards,
Marcelo Anelli

I suppose you want get error from SendNCmd call ?
Then try:
typedef LONG (WINAPI * _SENDNCMD)(LONG status, LONG * error, LPSTR buffer);
and
pFunc( status, &error, Buffer )

Saulius,

Thanks a lot! I need to learn C!!
now working without gpf using c calling directly.

Hi. I am having problems with this printer too. I am using FPCTRL.DLL with no problem at all, but for the UPLOADREPORTCMD function. I am trying to use this function to download Z report information to a text file, using this syntax:

nResult = UPLOADREPORTCMD(status, error, "U2S"+today+today,"c:\temp\out.txt")

The command runs with no error and file is created, but it contains just the following text: "@\"

I had tried using "U0Z" command instead with same result. Any ideas? What I am doing wrong?

Hi there,

I just need a basic step by explanation of what I need in order to be able to print on BMC fiscal printer

like for example
where I can get the dll from or if i can develop the dll myself
what i need to know to develop the dll if i have to develop it
what the dll is supposed to do
how I can call the dll

I am using vb2005

I would appreciate any kind hand
thank you
