1500 Graphics
The POSjet
®
1500 Printer conforms to the basic definition of IBM all-points-addressable (APA) graphic commands.
It is not designed to print large quantities of graphical data. The printer only prints graphics that are 2.5 inches wide.
At this time, there is not a graphics mode for Epson.
The POSjet
®
1500 Printer always prints in one of the native resolutions of 104 x 96, 208 x 96, 104 x 192, or 208 x
192 dpi. To provide compatibility with the standard IBM APA resolutions, the printer internally modifies the
graphics to print as expected. The printer converts the vertical resolution by altering the [ESC] J command (which
is typically used for vertical spacing) and adjusting it so that horizontal passes touch as expected. The requested
horizontal resolution is converted by data scaling. Because the vertical dpi of the printer is always greater, the
resulting APA graphics printed on the POSjet
®
1500 Printer are slightly smaller than the same graphic printed on an
impact printer. All of this is done transparently to the application; however, loss of resolution may result in some
modes. If desired the [ESC] * <m> command can be used to select the native resolution.
Note 1 If the POSjet
®
1500 Printer is used with programs that convert text to graphics, the printer is slower than if
the printer is sent ASCII text. The POSjet
®
1500 Printer is supported by a Windows print driver that allows
applications to select supported fonts.
Note 2 Generally, the horizontal graphic commands provide faster print than the APA graphic commands.
