Chapter 1. Technical Overview
Dot Densities and Plot Speeds
The T6215 printer supports Horizontal row plots (single and multiple row), Vertical
column plots, and specialized Graphic plots.
It supports the following horizontal DPIs: 40, 48, 60, 80, 90, 120, 180, and 240.
Scaled densities available on your printer are 50, 72, 75, 96, 100, 144, 150, 160,
and 200. All other selections will be approximated by conversion to the next
higher density.
Your printer supports the following vertical DPIs: 48, 72, 96,144, and 288. All
other selections are emulated through the use of scaling techniques.

Graphics Benchmarks
Two benchmark tests were used to rate graphics output on the T6215 printer. The
first was an AIAG label containing bar codes and block characters inside a box.
The second was a POSTNET label with one line of POSTNET bar code and four
lines of text.
The AIAG test consisted of a series of labels printed two across repeated vertically
with a 0.1 inch vertical space. The test was performed in two variations: Normal
AIAG printed with 60 DPI bar codes and Dark AIAG printed with 120 DPI bar
codes.
The POSTNET test consisted of rows of labels printed four across with one blank
line between each row. In addition, the POSTNET test was run with 4 variations:
Draft and Data Processing (DP) type styles for text/bar codes printed at 6 and 8 LPI.
Tests were timed, then results were converted into labels per hour. Code V and
PGL had the same results.
