We've had some issues with PCL6. Try running in PCL 5 mode. You might also try a driver from a printer closer to Windows98 vintage to see if that solves the problem. Also, the site mentioned that the issue that prompted the purchase of a new printer was the bank requesting magnetic toner for the MICR encoding. If the old printer was working properly, perhaps you might try a web search looking for magnetic toner cartridges for it.
