Nine emulations are available on the T6090: MT660, Genicom ANSI, HP2564C, Printronix
P600, Printronix P6000, IBM Proprinter III XL, Epson FX-100+, DEC LG01, and MTPL.
There are 6 resident type styles available on your printer. They include: Courier, Data Process-
ing, Draft, Gothic, OCR-A, and OCR-B. All font styles and the two output modes (Enhanced
and Constant Density Fonts for Draft and DP) are selected through the printer control panel.
These two font styles provide near letter quality (NLQ) printing on your printer. They print at
higher dot densities and use denser character matrixes. NLQ type styles provide greater
readability for reports and other text output.
Data Processing and Draft styles appear in two modes: Constant Density (CDF) and En-
hanced. Constant Density Fonts print at the same dot density regardless of the CPI. This
produces consistent print speed even when changing from one CPI to another.
Enhanced Mode provides higher resolution and a greater range of CPI's than CDF Mode.
Because Enhanced Mode uses a variety of dot densities, you should expect a change in print
speed of text when switching from one CPI to another.
These font styles print at 10 CPI only. They are used mainly for Optical Character Recogni-
tion.
The T6090 offers a variety of CPI's for use in printer output. Available CPI's are dictated by
the font style selected. Each CPI is based on one of twelve character matrixes and twelve dot
densities. Each matrix uses a specific number of dot columns for character composition and
intercharacter gap. CPI's are grouped in any given type style by the base CPI matrix used for
the group. These base CPI's are 10, 12, and 15.
