Chapter 1 The IGP/PGL Emulation

Graphic capabilities include boxes, vertical and horizontal lines with user- selectable thickness, logos, and special alphanumeric print features. Forms and graphic designs can be duplicated horizontally and vertically.

Alphanumeric data can appear as prepositioned “fixed” information (entered when the form is created), can be overlayed onto the form (positioned in a specific location after the form is created), or may be dynamically merged with the form.

Selectable Bar Codes provide appropriate bar codes for your application, using standard wide-to-narrow ratios. A wide selection of bar codes are available: Codabar; Code 39; Code 93; Interleaved 2 of 5; German I-2/5; ITF- 14; FIM; Matrix; MSI A through D; Code 128 Subset A, B, and C; UCC/EAN- 128; EAN 8; EAN 13; PDF417; POSTNET; PostBar; Royal Mail; Telepen; UPC-A; UPC-E and UPC-E0; UPCSHIP and UPS 11. UPC and EAN bar codes can also specify add-on data.

Expanded and Compressed Character Print attract attention where needed. Alphanumeric height and width are controlled independently for a wide range of character sizes up to 113 times the standard character size (up to 11.3 inches wide and tall). Compressed print sizes of 12, 13, 15, and 17 characters per inch (cpi) are available.

Rotated Alphanumerics permit new concepts in form design. Normal, expanded, and compressed character strings can be rotated 90 degrees clockwise or counterclockwise, or they can be printed upside down.

Logos are easily created using alphanumeric commands and add a variety of print and shading features for a “customized” appearance to forms, reports, and labels.

Reversed Print permits highlighting and contrasting by printing a dark background around white characters.

Automatic Increment/Decrement Capability allows batch form processing. You can identify individual numeric and bar code data fields, which include automatic increment or decrement functions.

Scaling Capability permits graphic elements, such as corners or boxes, to retain their physical shapes and sizes when printed in a horizontal and vertical density other than the base density of 60 x 72 dpi.

Multinational Character Sets provide 32 international character sets, each 96 characters in length. This feature also allows you to create your own character sets using characters defined and stored in memory.

Extended Character Sets provide 33 extended character sets, these also having 96 characters. These are also stored in memory.

How the IGP Operates

IGP is an emulation that allows printing of sophisticated graphics and bar codes.

The printer performs commands based on the current mode. These modes are discussed in more detail beginning on page 15.

When the printer is receiving or printing text, it is in Normal Mode. Any time the printer is on and is not processing IGP commands, it is in Normal Mode.
