12-2. Vertical Printing Format
FUNCTION
• A clear command for elongated character command for Japanese
7-bit code.
• Ignored when codes other than Japanese 7-bit code are used.
• Initial start load command to load electronic Vertical Format Unit
(VFU). Data preceded by GS code will be stored in VFU memory.
• TOF code must immediately follow GS or the entire format load
will be cancelled and the printer will revert to the programmed
format. When the power is turned on, the printer is set to the
preprogrammed format.
• The end of load command for VFU loading.
• TOF must immediately precede RS or RS is ignored and the
printer will revert to the preprogrammed format.
• Vertical tab start command combined with the following 1 byte
which defines either (A) the number of channel of VFU where the
format to be followed is contained or (B) number of lines to be
fed expressed in weighted binary.
• Feeds the form up to the next TOF position,
in
case that no tab
is found in the specified channel at a line below (in case of reverse
mode, above) than the current position.
The binary value of
N3N2Nl NO must be between 0 and 15.

• X may be either 0 or I.
Note:
When C
=
I, the form is fed to the next bottom or TOF
position.
When C
=
0, the code is ineffective.
The code is ineffective other than when I -:; C -:; 6.
When the code is ineffective, the reception of US code is
cancelled.
• This code doubles as a print command with DIP SW (SWI-7)
closed. When SWI-7 is open, US/VT after print data is ignored.
• This is an ignore code.
The user has the option of programming his own vertical format, or using the pre-programmed format
in the M8510A printer. The pre-programmed format consists of Top of Form at line I, Bottom of
Form at line 66 (or 72), and a vertical tab in channel 2 every sixth line down the form.
If
the EVFU is
not programmed by the user, or if the EVFU programming is incorrect, the printer will default to the
preprogrammed format.
