The following table shows the maximum number of characters per line for
each character pitch.
IBM BASIC will not normally allow printing of more than 80 characters
on a line. Enter a WIDTH statement to supersede this limitation.
PRINT MODES
Near Letter Quality, Utility, High Speed Draft & Italics
The default setting of the printer when switched is utility mode. In this
mode the printer prints bidirectionally: that is, printing one line from left
to right, the next line from right to left, etc. This printing method increases
the printer's speed so it prints 800 characters per second. This mode is used
for high-volume printing and printing program listings or rough drafts.
If a little print quality can be sacrificed for speed, select high speed draft
(HSD) mode. In this print mode, the printer prints at 1066 cps in 10 CPI.
However, draft mode is unavailable for printing using double width,
emphasised, enhanced, italics or proportional spacing.
Where good quality printing is required, use near letter quality mode
(NLQ). In this mode the printer prints at a slower rate of 200 characters per
second because it prints each line twice. On the second pass, the printer
fills in between the dot pattern printed on the first pass to form a sharp,
crisp letter.
To highlight paragraphs or keywords, the printer can also be set to print in
italics.
