P6+ - by Les Kneeling

     P6+ is a printer control program, specifically for the NEC P6+. It can 
be used either as a desk accessory or as a .prg depending on the name it is 
given. Calling it P6+.ACC makes it into a desk accessory, anything else will 
make it a program.

The sections are:

Font
     Clicking on the arrow buttons will cycle through the fonts available 
     on the P6+. As the font changes the pitch will be updated to the first 
     size available for that font.

Pitch:
     Clicking on the arrows cycles through the pitches available for the
     currently selected font. The proportional fonts only have one pitch so 
     the display will not change. Unlike the front panel of the printer 
     the program does not show the pitches created by combination with 
     condensed mode.

Page Length:
     The page length can be set from 0 to 99 lines. The actual length of 
     the page in inches will depend on the lines per inch setting. The 
     default setting (click on the number itself) is 69.

Lines per inch:
     Only six and eight lines per inch are available. Clicking on the arrows
     will toggle between the two. The default is 6.

Left Margin:
     The left margin can be set from 0 to 80. The default is 0.

Justification:
     The four types of justification are cycled through when the arrows are
     clicked. The default is left justify. The arrows mean:
               <-<-      left justify
               -><-      centre
               ->->      right justify
               <-->      full out

Tab Size:
     The tab size can be set from 0 to 10. The default is 10.

Style:
     This is a panel of buttons which can all be de-selected by clicking on 
     the background panel. Clicking on the buttons selects the appropriate 
     style.

Skip Over:
     When the button is selected the skip over perforation is activated. The
     skip is one inch.

Quiet
     When the button is selected the printer is placed in quite mode, 
     otherwise it is normal.
UniDir
     When the button is selected the printer will print uniderectionally, 
     otherwise it will print bidirectionally.

     All of these settings will be sent to the printer when the Set button 
is clicked. The remaining buttons have immediate effect.

Paper Control:

     The up arrow moves the printing position one line up.

     FF performs a form feed.

     The down arrow moves the printing position one line down.

Reset:
     This sends the reset command to the printer.

Print a file
     This button brings up a file selector. choose a text file from the 
     selector and click on OK to print it.

Save
     The current settings will be saved in a file called P6+.SYS in the root 
     directory of the boot disk in the case of a desk accessory, or the disk 
     from which the program was launched. Once this file has been created, 
     it will be automatically loaded and used next time.

Set
     Send the current settings on the dialog to the printer.

Exit
     Quit the program without sending the codes to the printer.

     I have provided a complete listing of the accessory so that you can 
modify it to produce a version for your own printer. The original was written 
in Laser C. You will probably find that if you compile the program with 
another compiler the automatic switchover from accessory to program will not 
work. I would suggest that you set the ACCESSORY variable to TRUE or FALSE 
instead of calling get_operation_mode().
