Color management problem

Hi

Can anyone have a solution for the following issue?I mentioned that i read all the topics regarding this issue.

I have 2 Epson L1800 printers connected to 2 different PCs.i create the jobs in Corel and after that i export it in PDF.

Everything is good until this point.

The problem is that, even i use the same network group document for printing, one printer (let's call it printer A) prints the right colors and the other printer (Printer B) prints wrong colors.

The Color management problem of the document i guess is out of question since i use the same document for printing.

The printer color management from devices and printers tab are the same on both printers.

I switch the printer A (the one which prints good) to the other PC and the print is fine.So the color management of the document is fine.

I switch the printer B (the one which prints bad) to the other PC and the print is wrong as it was on the other PC. So the printer is the problem.

Also the printer drops a too much ink. 

Can this be a hardware problem which affects also the color?

thanks for support.
