+ * Download character 'c', assuming that the corresponding font file is in
+ * .pk format. Therefore, 'pktopxl(c)' is called which converts the pk-coded
+ * character into the corresponding byte aligned pixel pattern, stored in
+ * 'pxlbuffer'. 'pktopxl(c)' also determines the global variables
+ * c_width, c_height, c_hoffset, c_voffset.
+ *
+ * For landscape mode the pixel pattern then will be rotated and stored at
+ * the end of the character pixel pattern at 'endofchardata' in pxlbuffer.
+ * The appropriate pixel pattern then is downloaded, i.e is put in bitfile,
+ * if possible, including the corresponding character descriptor for the
+ * printer. For those characters which don't fit into the printer's maximum
+ * character cell (use_count < 0) raster information is stored in *gfont
+ * and memory space is allocated to store the corresponding pixel pattern.
+ * Stored characters are drawn in graphics mode by 'drawchar(c)'.
