Dos Based printing in VB while using printer object.

[Sanjay K Dixit]

Dear Sir,

Graphical printing is slow for Dot Matrix Printer (DMP). Whenever I Start printing on DMP from VB application using printer object. It is slower than MS DOS based printing.
I want to print on DMP as MS DOS based Fast printing from VB application using Printer Object in VB ?
Please help me out.

With Lov Prg.
