FUNCTION

Delete all temporary and permanent fonts

Delete all temporary fonts (another way to delete

all temporary fonts is to send a reset command)

Deletejust the font with the most recently specified

Delete just the last character of the font you have

downloaded

Make the current font ID temporary

Make the current font ID permanent

Make a temporary copy of the current font

A bit of explanation about that last function 6: When you give a font ID to

anyfont you first need a temporary copy of that font in memory. That copy

is already there for downloaded fonts. But you will need function 6 to create

a temporary copy of an internal or cartridge font.

Here’s how to assign ID numbers to an internal or cartridge font. You first

select the font, then send the Font ID command to give itan ID number, and

finally copy the font into memory with Font Control function 6. If you want

thatcopy to stay in RAM when you reset the printer, youconcludeby sending

Font Control function 5.

4.5.9 Example: Controlling fonts

Let see how those last few commands work. translated into BASIC.

Pretend you want to make a short testwith yourcurrent font (itdoesn’t matter

what itis):you want to print what’s inASCII table positions 128through 130.

There’s nothing there in your normal Roman-8 symbol set, but some other

sets keep control codes or international characters there.
