“V indicates that the following character is a control code. “V[ enters the cESC> code. <ESC> has character code 27, and “[” is the 27th character in ASCII sequence from A. Similarly, “VA enters the control code cl>. See your DOS manual if you need further information about EDLIN.
You can now set up the printer by sending it the file LQELITEDAT. To avoid unnecessary logging of commands, switch
A>COPY LQELITE.DAT PRN
A>PRINT README.DOC
For greater convenience you can make a batch file that will set up the printer
and print any specified file with a single command. To create such a batch- file with the name LQPRINT.BAT, type in the first four lines shown next.
*Z means to press the CTRL and Z keys simultaneously. To use this file to print READMFDOC, type the fifth line.
A>COPY CON LQPRINT.BAT
COPY LQELITE.DAT PRN PRINT %1
^Z
A>LQELITE README.DOC
The first above line is a copy command from the CONsole screen to a file named LQPRINT.BAT. The next two lines are the contents of this file. The
%1is a dummy parameter: whatever file name you type after LQPRINT will be substituted for %l and printed.
