I am having an issue with a client that is still using a dos based program. For printing I have had them use a mapped LPT1 port which works great with every single printer in the office. THey replaced one printer with a Xerox workcentre 6015, and that printer will never print using this method. When I change the mapping to print to a Xerox workcentre 5230, or anyother printer in the office it works without a problem. does anyone have any advice? The network connection to this printer is working as well as normal windows printing.
