HP 5961-0509 manual Using HP-GL/2 text, 24-6Programming Hints

To ensure compatibility with future products, select fonts by specifying all of the font characteristics. If all of the characteristics are not designated, the primary and secondary font tables in the printer may not contain the correct information to select the requested font from those available in the printer.

The shortcut method of font selection is not recommended (as documented in some previous font product literature) and may not result in the desired font change. This is due to the increased number of available fonts in the printer.

The transparent print data command is required to access printable characters with character codes in the decimal range of 0, 7-15, and 27 in the PC symbol sets.

All information about the design of a font, as well as the design of its characters, can be found in the font and character descriptors.

A Space control code is executed when an attempt is made to print a non-existent character.

Using an ID number which has not been associated with a font results in no font change.

Font designers should not define the space character. Use the printer’s Space control code should be used for character spacing. Defining the space character in the font results in a significant reduction in performance and inhibits the HMI command with proportional fonts.
