Hi,
1. PRN files can be obtained when you select the "Print to File" option in the Print dialog. These PRN files are written by the printer driver in a language that can be interpreted by the given printer and you can
simply copy this file to the printer in the DOS prompt.
2. PLT files can be saved while you select "Plot to File" in the Plot dialog. These are HPGL2 files that you can simply copy to the printer in the DOS prompt.
Examples:
Sending a PRN/PLT file to a printer/plotter connected to the local LPT1 port:
copy /b filename.prn lpt1
or
copy /b filename.plt lpt1
Sending a PRN/PLT file to a printer/plotter shared on an ethernet network:
net use lpt2: \\server\designjet
copy /b filename.prn lpt2
net use lpt2: /delete
or
net use lpt2: \\server\designjet
copy /b filename.plt lpt2
net use lpt2: /delete
A good utility program here
Regards
Fernando
