BBC Printer Fonts Designer
This program allows the user to design his or her own printer fonts
and allows them to be use as the normal character set when printing. The
program can also double as a very effective User Defined Graphics editor.
When redesigning the fonts the program does not change the font stored
in the printer ( this can only be done on a few printers ), instead it
holds each character as a set of graphics commands for the printer. When
a character, say A, is sent to the printer the program intercepts the
ASCII value 65 and instead sends a graphics sequence to the printer.
To do this two programs are needed. Firstly the font designer and
secondly the intercept program. Once the fonts have been designed with
the Font Editor a program is generated by the editor that is activated by
a simple * command call to the disc drive. This calls up the Trapper
program.
Use
Once the editor is loaded and run it presents 10 options selected by
pressing the appropriate key. The options are:
Compile Fonts for Use
Once all the fonts have been defined this option should be selected to
generate the Trap program. The option will prompt for a filename and a
run time load address. Although any ( disc ) filename can only be 7
characters long I have not placed a limit on the length of the filename
entered as the user may wish to include drive numbers and/or directory
settings, these conditions apply for all filenames requested by the
program. The run time memory address is important as this is the memory
the Trap program will reside in while running. The program needs 5
consecutive pages ( 1280 bytes - mainly character data ). Any free memory
can be used. When entering this address it must be in hex form e.g. enter
20480 as 5000 not 20480 or even &5000. This restriction is because, while
BBC BASIC can convert hex strings to numbers it can only convert numbers
to hex strings with the ~ function and the print command sending the
result directly to the screen.
Save/Load Fonts
These option allows all the fonts currently in use to be saved and
reloaded from a disc file.
View Fonts
This option allows all the fonts to be viewed in turn.
Test Print Character
When selected this option will prompt for the character to be tested.
It will then send 10 of them, separated by spaces, to the printer. This
option and the last are designed to help give an idea of the final
overall effect.
Give settings for UDG
As well as providing the printer font function the basic principle of
designing a font are the same as designing a User Defined Graphic ( UDG
). This option gives the VDU 23 code that must be issued for the
specified character to be generated as a UDG on a BBC. ( The x in the
command stands for whatever UDG is being defined e.g. any character
number depending on how the UDG's have been exploded. )
Set all Characters to Default
This option is very useful when first redesigning the character set. It
simply sets every character ( ASCII 32 to 126 ) to their default settings
e.g. how the BBC defines them. NOTE: these will not be the same as the
printer since each printer has it's own definitions of each character.
Some printer manuals list the definitions used by the printer.
*Command
Although not listed on the menu, typing * at the menu will allow any *
command to be issued.
Edit Fonts
I have left this option to last because it is the most complicated.
Once selected the program will prompt for a character. As with the other
options which prompt for a character you can enter the character directly
from the keyboard by pressing it on the keyboard and then RETURN. If,
however, you prefer, pressing RETURN on its own will prompt for the ASCII
code for the character.
Once the code is selected the program produces an 8 by 8 grid on which
the character is displayed clearly. On this grid is placed a cross to
help with altering the character. To the left of the grid are details the
cross's position, the character being edited and how the character
currently looks as a UDG.
The cross can be moved by pressing the appropriate cursor key to move
the cross and pressing RETURN to toggle the square between one and off.
As well as this the function keys allow more option to be selected.
Function Key Normal Action Shifted action
f0 Clear Grid Inverse Grid
f1 Fill Grid Change Current

f2 Vertical Fill Vertical Clear
f3 Horizontal Fill Horizontal Clear
f4 Restore Default Set current character

character to with another

f6 Copy another Activate Printer
character to the Dump *
the current character
f7 Vertical Inverse Vertial Reverse
f8 Horizontal Inverse Horizontal Reverse
f9 Exit to Menu Flip character
* You will have to insert you own printer dump program at the very end
of the program e.g. my own Printer Dump Program ( PDP ) or it's close
relative Printer Dump ROM ( PDR ) which have already been broadcast by
Ceefax.
As well as moving the cross pressing one of the cursor keys while
holding SHIFT down will allow the character on the grid to me moved up,
down, left and right.
I hope the functions provided are comprehensive enough without
being too numerous and divergent to understand. Some experimentation will
probably be needed before any "major works" can be produced.
