When you want to set all your laser printer’s parameters back to their
initialdefault values (some people call this “initializing” the printer), send
thiscommand:
<ESC> E
.The printer will finish printing any pages left in its memory before
resetting the parameters. Resetting clears unneeded temporary fonts from
your printer’s memory. Any permanent fonts or macros you have down-
loaded, however, will still be there after you send areset command.
Permanent and temporary fonts are described at the end of this chapter’s
“Controlling Fonts” section.
4.2.5 Example: Printer controls
Let’s see what happens when we put these commands together. Say you
have just turned on your laser printer. What happens when you send the
following commands to your printer?
<ESC> Z
<ESC> E
<ESC> &/2h 2X
As aBASIC program these would look like this:
NEW
10 WIDTH “LPT1:“,255
20 LPRINT CHR$ (27);“Z“
30 LPRINT CHR$ (27);“E”
40 LPRINT CHR$ (27);“&12h2X”
RUN
First, if it is working properly the printer prints atest print with all the
characters in itsdefault font (Courier).
Nextthe printer sets all its parameter values—including feed selectionand
number of copies —to their initialsettings.
‘The last command does two things: it tells the printer to accept paper you
will feed in yourself, and to printeach page two times. This is handy when
you want two copies of aletteron preprinted letterhead.
