slip modes of other Series 90PLUS Printers will not function.

2.4 Receipt/Journal Printer
The Model 92PLUS receipt/journal printer adds the journal feature to the Model 91PLUS receipt printer. The
journal take-up is able to rewind the second copy of the 3.5-inch diameter 2-ply paper roll (125 feet).
The receipt/journal printer does not have the ability to validate or handle slips. Commands that operate
validation and slip modes of other Series 90PLUS Printers will not function.
2.5 Receipt/Journal/Validation Printer
The Model 93PLUS printer adds an independent validation capability to the Model 92PLUS. There are two
methods of form validation on the Model 93PLUS.
1. Top insertion validation. The form is inserted from the top and extends out the left side and/or top of the
printer. It rests on a fixed form stop. Under software control, printing can be from a minimum of two lines
to a maximum of 17 lines at 42 characters. Throughout this manual, top insertion will be termed “Validation
Mode.”
2. Front inserted validation. The form is inserted from the front and extends out the left side and/or front of
the printer. In front insertion mode, the form is loaded to the first line of print under firmware control.
Printing then begins from the top of the form down. Throughout this manual, front insertion will be termed
“Slip Mode.”
All Series 90PLUS validation printers have both validation and slip modes. The validation/slip movement is
independently controlled from the movement of the receipt and journal. Either can be moved alone or in sync
with the receipt/journal movement. The validation/slip movement will be under software control but set to
independent validation by default.
2.6 Receipt/Validation Printer
The Model 94PLUS receipt/validation printer adds validation to the Model 91PLUS described above. The
Model 94PLUS is a Model 93PLUS without journal take-up.

Table 1 Character specifications
3.1.1 Character Generation
All the character sets and modes are based on one of two character cells, 10 wide x 9 high or 12 wide x 9
high. Double-wide mode is twice the width of normal mode, 20 wide x 9 high or 24 wide x 9 high.
In utility print mode, the character cell consists of five full-dots and five half-dots horizontally by nine full-
dots vertically. The character is a 9 x 9 character. In high speed draft (HSD) mode, the character cell is
shortened by one half-dot and one full-dot column yielding a 7 x 9 character.
Each character is justified to the left of the cell. The first four columns of the full dots and the first three
columns of half dots are used to generate the character in high speed draft. In utility mode, the first five
columns of the full dots and the first four columns of the half dots are used. The last full-dot and the last two
half-dots are used for character spacing in both modes.

Figure 1 Single-wide character
The example above, which only holds true for the 12 cpi mode, shows full dots adjacent to each other in the
character cell. The 10 cpi mode allows a gap between adjacent full rows; 17 and 24 cpi allow an overlap of
full rows. The printer cannot print adjacent full and half dots in any single row. Some graphics (double-
density, half-speed) allow adjacent rows to be printed by slowing the print speed by half. Slowing the print
speed allows the time between half and full columns to be the same as the time between full columns in full
speed operation.
The following illustration shows the use of full and half dots as well as descenders to form characters.
