I have the same problem with my old Centura programs.
I occurs with Win2000 and XP.
Printing in Centura gives Error #8
This only happens if the printer is connected via USB or is a Network printer on another PC (98,2000,XP).
There is sometimes a complicated workaround using the printer a second time with "Printer-Pool" and "NetUse". But some printers seem not to support Printer-Pool.
Any more suggestions? Is there a Centura Update for repbi11.exe?
