I am trying to output information from a program I have written. My problem is that the printer is connected to the USB port and it will not respond. I have a header file with all the relevant escape codes for my printer (Lexmark Z52), I have tried prn_ptr=fopen("LPT1","wt") and prn_ptr=fopen("PRN","wt") but neither work.(fopen is not returning NULL).Can anyone tell me how I can access this printer please and also, is it possible to check if information is being sent to a port (serial, parallel or USB). Any help would be gratefully appreciated.I am using Borland 4.5 on Windows98 and must use ANSI C (Yes it is a project, I have tried what little I know but am stuck)
