Overview

The PRESCRIBE emulation option for Lexmark laser printers is an extended version of the firmware that includes a PRESCRIBE language processor. It enables the printer to replace printers in large accounts where the PRESCRIBE printer language is used.

Kyocera does not offer a single standard version of PRESCRIBE across all its products. Therefore, the emulation compatibility of this version is based on testing with customer application test files and an extensive set of engineering command-level tests.

This technical reference manual describes the capabilities of the PRESCRIBE emulation option and highlights the key limitations. Customers must consider these limitations in their certification testing.

Supported printer models

Installing the PRESCRIBE emulation option

For information on installing the PRESCRIBE emulation option, see the installation instructions that came with the option, or see the printer User’s Guide.

Tips

Flash memory and hard disk support

PRESCRIBE downloaded fonts (LDFC) and PRESCRIBE macros can be stored on either the flash memory or the printer hard disk. Programming is done using the Resource Save setting.

Note: The ICCD and WRED commands are not supported.

Memorex printer compatibility mode

The PRESCRIBE emulation option includes a custom extension to support an alternate font number table which is compatible with Memorex system printers. The font number mapping is as follows:

Memorex font number

Standard PRESCRIBE font number

1

1

2

6

3

10

4

15

5

2

6

17

7

23

8

29

9

34

10

19


The font number is the parameter used with the FONT command. This font number mapping is invoked by the Memorex Express start sequence, (O&, instead of !R!.

Print jobs that use the Memorex Express start sequence can often be automatically sensed as PostScript® emulation. To prevent these print jobs from being processed as PostScript emulation, they must be wrapped with a PJL ENTER LANGUAGE sequence into PCL® emulation. Or the PostScript SmartSwitch must be turned off for the respective input port. The following is an example of how to wrap the print job with PJL:

UEL1

@PJL ENTER LANGUAGE = PCL5

ESC E2

(O&3

.......4

EXIT;5

UEL6


Overview of limitations

Although the PRESCRIBE emulation option works in most environments, there are environments where the option is not applicable.

Incomplete command set

Most PRESCRIBE II commands are not supported. Some commands are partially supported. For example, the BARC (bar code) command is supported for only a subset of the possible bar code types.

One base emulation supported

Kyocera printers support a number of base emulations. The PRESCRIBE emulation option supports PCL 5e only. PCL 5e emulation is used for the entire print job, or the print job is formatted using PRESCRIBE commands.

Some print jobs depend on a default PRESCRIBE environment based on an emulation of IBM ProPrinter. A ProPrinter default environment setup is supported by the PRESCRIBE emulation option. See the FRPO section for details (under the P1 parameter section). Starting with the P30 release, the LinePrinter setup is also supported.

Font substitution

Kyocera supports a large number of resident bitmap fonts. The PRESCRIBE emulation option supports many of these bitmap fonts by substituting a resident outline font. Hence, some of the fonts differ slightly in style and size, but the spacing of the substituted fonts match Kyocera.

No edge-to-edge printing

Many Kyocera printers allow printing to the physical edges of the paper, which is commonly referred to as edge-to-edge printing. The PRESCRIBE emulation option allows printing within 2 mm of the physical paper edge. See the FRPO section for details (under the L parameter section).

Certification test process

The PRESCRIBE emulation option must be thoroughly tested with the customer's applications to determine if it is usable before a customer makes a significant investment in this solution.

If problems are found that do not fall under the set of limitations in this document and need to be investigated further, then the following information must be available:

Note: Customers must recertify new versions of the PRESCRIBE emulation option before purchasing it in large quantities.
