What is PEPW and IVFO and where it can be used.

IVFO - All Epson printer is made compatible to work with Epson drivers and standard softwares. When we convert them and use RIP software, the cr motor is overloaded. 

Main board detects use of RIP softwares and signals CR motor to work at reduced speed. IVFO module bypass these signals and avoids printer slow down. Note : It doesn't protect or avoids detoriation of CR motor. Today or tomorrow you have to replace CR motor but IVFO utilitiess full strength and life of the CR motor. 

You can use IVFO module with any Epson printer. You can also use it in combination with Ziggroll Roll printing software to manage roll printing.

Note : Its recommended to use ivfo at the time of modification. If you are already experiencing speed slow down, you might have to replace CR motor and then use IVFO.
