Hi,

My printer is Epson EU-T432.
Using ??? to sent those ESC/POS command, it is working fine
However, when I use a mixture of ??? and ??/?, it
does not work well as ??? is directly to printer,
but ??/? go to the printer driver, which will
first auto cut the paper and proceed.

I confused why your printer is working fine.
In addition, I was told that both the ??? and
?? don't work well with each other.

However, I might be wrong due to my limited
knowledge on printer.




>Use ?? then. This is a snippet of our code and it works on our dot matrix printers in Epson mode:
>

>set console off
>set printer on
>
>??? opt
>??? av_lpi8
>??? av_cndsprt
>
>*---Print Contract
>
>? " -------------------------------------------------------- "
>? "| AGREEMENT                                              |"
>?? Co_Line1 AT 1
>?? In_Line1 AT 90
>*--Etc.
