Graphics commands

Graphics commands are used to download raster data to form bit map images. Expressed in dots corresponding to bits, images can be created in rectangular shapes with a variety of fill and shading patterns.

When the printer receives graphic data that is incomplete, e.g. the data has fewer bytes than the window size, the next Form Feed commands may be ignored, causing unpredictable results.

Raster Graphics Resolution

Purpose The Graphics Resolution command controls the resolution (number of spots per inch) used when printing downloaded raster information as bitmap graphics. This command must precede the Start Graphics command

Note: When the page buffer is set to ºFULLº (full page imaging) in the LJ2D emulation submenu, the memory the 4213 dedicates to this imaging is no longer available for user downloaded fonts or graphics or any other temporary use. This means that a full page graphic that prints completely in ºPARTIALº imaging may not print if the page buffer is set to º1 FULL or 2FULLº.

Example: A 2.5 MB system with º2 FULLº page imaging can store only a small number of fonts (about 8 fonts of 25KB each) or graphics. That same 2.5 MB system with ºPARTIALº imaging could store 2 full page graphics or over 80 25 KB fonts. The same full page graphic prints completely in partial imaging, but not in ª2 FULLº page imaging.
