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 ”FULL” (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 ”PARTIAL” imaging may
not print if the page buffer is set to ”1 FULL or 2FULL”.
Example: A 2.5 MB system with ”2 FULL” 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 ”PARTIAL” 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 “2 FULL” page imaging.
