Epson Stylus 1500 [302/573] Mixing text and bit image graphics with esc p 2 printers
Sending Graphics Data R-71
At the end of the line, send the CR and LF commands. Move the horizontal print
position as necessary. Then send the ESC * command for the next line of graphics.
Note:
Since the vertical dot density during 8-dot mode is different for 9 and 24/48-
pin printers, printed graphics will differ slightly (graphics on 9-pin printers
will appear slightly compressed vertically).
You must send the ESC * command for each line of graphics.
Mixing text and bit-image graphics with ESC/P 2 printers
ESC/P 2
ESC/P 2 printers can process more than one line of data at a time; this allows for
advanced features such as scalable fonts and raster graphics.
More memory has been provided for processing data than previous ESC/P
versions. By processing data within this memory before printing, mixing bit-
image graphics and text of all point sizes is possible.
To provide the most efficient processing of data in the memory available,
ESC/P 2 has the following rules:
You cannot move the vertical print position more than 179/360 inch (one dot
less than 1/2 inch) in the negative direction.
You cannot move the vertical print position in the negative direction if you
have just sent graphics data, or if the print position would move above
previously printed graphics data.
Because of these rules, you should process data with text data always leading
graphics data by 1/2 inch.
Follow the steps below for this process.
1. Use the ESC + 48 command to set the line spacing to match the print head
height.
2. Send the first 1/2 inch of text data to the printer. You can print any
combination of fonts (large and small point sizes, etc.) on multiple lines;
however, make sure the baseline of all characters is located within this 1/2-
inch.
3. Use the ESC ( V or ESC ( v commands to move the print position to the top of
the 1/2-inch zone.
4. Use the ESC * command to send one line of graphics data (see the previous
section). End the graphics line with the CR and LF commands. Note that the
height of one line of graphics is equal to the height of the print head (48/360-
inch).
