RS-232 serial interface, Printronix P4280, Printer Command and Control
Three printer emulations are selectable at the control panel and controlled by software:
1) Printronix P-Series emulation
2) Printronix P-Series XQ emulation
3) Serial Matrix printer emulation (similar to the IBM Graphic Printer, but with more features)
Note: All emulation software, fonts, and character sets are permanently stored in printer Read–Only Memory (ROM).
Output Control Five modes for printing text:
1) Near-Letter Quality (NLQ)
2) Data Processing (DP)
3) High Speed (HS), with a choice of three vertical densities
4) Optical Character Recognition Font A (OCR-A)
5) Optical Character Recognition Font B (OCR-B)
• Selectable alternate horizontal and vertical dot densities enable you to tailor output to a wider variety of printing requirements.
• Selectable forms length
• Character attribute specification:
1) Selectable pitch: normal, expanded, and compressed
2) Emphasized (“shadow”) printing
3) Double strike (bold) printing
4) Automatic underlining
5) Superscript and subscript printing
6) Double high printing
• Resident multinational character sets
• Downloadable character sets and international languages. You can add international languages to the font library and access them in both P-Series and Serial Matrix emulations.
• RibbonMinder, a ribbon ink–life indicator
Graphics and Vertical Formatting
Several graphics and vertical formatting features are available:
Two built-in graphics generators:
-
P-Series odd-even dot Plot Mode
-
Bit-image graphics (serial matrix printer emulation) Programmable electronic vertical formatting provides rapid vertical
paper movement to specified lines for printing repetitive and continuous forms.
