Graphic Mode
The Series 150 Printer conforms to the full definition of IBM all-points-addressable (APA) graphic
commands. The printer will only print graphics that are 2.4 inches wide. This at times can make it
difficult to use off-the-shelf graphic generation programs.
If the Series 150 Printer is used with programs that convert text to graphics, the printer will be slower
than if the printer is sent ASCII text. The Series 150 Printer is supported by a Windows’ print driver
that will allow applications to select fonts that are supported by the printer.
The Series 150 Printer is not designed to print large quantities of graphical data. If the printer is
asked to print an excessive amount of black, it will break down the job into multiple steps. This
protects the printer but slows the printing time. The printer should not be requested to print a white
on black image.

Standard APA Graphics

Function Print single-density graphics (60 h x 72 v dpi)
ASCII [ESC] K <n>1 <n>2
Hexadecimal 1BH 4BH <n>1 <n>2
Decimal <27> <75> <n>1 <n>2
IPCL none
Description This command prints n1 + 256 * n2 bytes of single-density graphics (60
dpi).
Function Print half-speed double-density graphics (120 h x 72 v dpi)
ASCII [ESC] L <n>1 <n>2
Hexadecimal 1BH 4CH <n>1 <n>2
Decimal <27> <76> <n>1 <n>2
IPCL none
Description This command prints n1 + 256 * n2 bytes of double-density graphics (120
dpi) at half-speed allowing full and half dots to be printed.
Function Print full-speed double-density graphics (120 h x 72 v dpi)
ASCII [ESC] Y <n>1 <n>2
Hexadecimal 1BH 59H <n>1 <n>2
Decimal <27> <89> <n>1 <n>2
IPCL none
Description This command prints n1 + 256 * n2 bytes of double-density graphics (120
dpi) at full speed with no consecutive dots. (Full-speed double-density
graphic mode is generally used to print 120 h by 144 v dpi resolutions in
two passes).
