TRANSPARENCY MODES

Page 11-5

Here are some examples (using the default Trigger 1) that show the output sent to the printer upon receiving input from the coax host when using MD- Laser pseudo transparency:

Host Input to ULTRA

ASCII Output

¢C2616263¢

abc

¢C2 61 62 63¢

abc

¢C2 41 02*42 05*43¢

ABBCCCCC

If Option #55 is set to “No,” the default, then the trigger and all of the otherwise transparent characters will be printed normally, as indicated by the active translate table (see Section 7 — Translate Tables).

Laserpage Pseudo Transparency

The ULTRA is capable of supporting Laserpage, a software product that allows IBM AFP data streams to be printed to Xerox and Hewlett-Packard laser printing systems. Laserpage uses a transparency mode similar to Trigger 1 + Trigger 2 PTM, but with repeat count capabilities.

If Option #59 is set to “Yes,” when the ULTRA detects Trigger 1 followed by Trigger 2 in the data stream, it begins checking for valid pairs of hexadecimal characters. When the ULTRA detects an asterisk, it combines the two bytes prior to the asterisk to form a count byte, and it combines the two bytes after the asterisk to form a repeat byte. The ULTRA then sends out the repeat byte to the printer the number of times indicated by the count byte. This provides some compression of graphic data. Normal pseudo transparency then resumes.

Here are some examples (using the defaults for Trigger 1 and Trigger 2) that show the output sent to the printer upon receiving input from the coax host when using AGILE Laserpage pseudo transparency:

Host Input to ULTRA ASCII Output

¢$616263¢abc

¢$4102*4205*43¢ ABBCCCCC

If Option #59 is set to “No,” the default setting, then the trigger and all of the otherwise transparent characters will be printed normally, as indicated by the active translate table (see Section 7 — Translate Tables).
