Is there a difference between this two? Valuejet is from Mutoh while PrismJet V is from SignWarehouse and it cost cheaper. I want to know from guys who owns a PrismJet V or anybody who knows Valuejet. I just want to make sure that is the same printer with different name. Thats what signwarehouse told me. Are the print quality and speed the same? Please I need some advice. Thanks in advance.
