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 downloaded,
however, will still be there after you send a reset command. Permanent and
temporary fonts aredescribed at the end of this chapter’s “Controlling Fonts”
section.
Example: Printer controls
Let’s see what happens when we put these commands together. Say you have
just turned on your laser printer and selected LaserJet III emulation on the
front panel. What happens when you send the following commands to your
printer?
<ESC> z
<ES- E
<ES0 &/2h 2X
As a BASIC 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 a test print with all the
characters in its default font for this emulation (Courier).
Next the printer sets all its parameter values- including feed selection and
number of copies- to their initial settings.
The last command does two things: it tells the printer to accept paper you will
feed in yourself, and to print each page two times. This is handy when you
want two copies of a letter on preprinted letterhead.
You can now send your letter from your word processing program to the
printer and feed in those pages. When you’re done, you may want to send the
<ESC> E command one more time.
