Examples of Printing in Page Mode
The first example is text on two lines at 9 dots per line with an auto-line feed.
The text on the third line is double-high. See the sample printout and the sample
code.

“ Double high”

In this example, you enter page mode and select a print area of 400 x 400 half-
dots (200 x 200 full dots). The printer enters the text on the first line of the
selected print area until it reaches the right edge of that print area, at which
point a line feed is automatically inserted (in this case, before the space
following “ feed” ).
Before doing a line feed and entering double-high, change the line feed spacing
to 42 half dots (21 full dots). This will ensure that the double-high line does not
overlap the line above it. The Eject Slip command (0C) prints the page.
