Error 1957, Unable to Access Printer Spooler

[Matiwos]

I am installing an Epson TM-U220 on one Computer with RetailMan. The Printer Prints without any Problem fromWindows applicaions. But when I try to print from RetailMan, I get the above error message. In Maintenance--Hardware, I have chosen Epson U220B as the Printer, and the Windows driver, but I still get the same error message. I have checked previous forum postings but could not get a solution. Please help resolve this problem.
