Needed help on printing from C# and printer

[Guest]

Dear All,

I'm having a problem here with C# and Epson TM-L90 Thermal Printer. The
problem is, in C# I use 'PrintDocument' to send 10 lines with font 'Arial' to
the printer to print, but it prints quite slow.

When I try to using VB6 to print, it prints quite fast, but the method I
used in VB6 is as below :-
Open "LPT1" For Output As #1
Print #1, "THIS IS A TEST"
Print #1, "THIS IS A TEST2"
Print #1, "THIS IS A TEST3"
Close #1

What is the problem here ? Can I use other method to print besides
'PrintDocument' in C# ?
Please provide examples on this.

Thanks in advance.


Cheers,
Mae

You need to open a handle to LPT1 and then create a FileSream from this
handle, then you can simply output text to the stream as you did in VB6.
