Epson Stylus Pro XL+ [235/573] Recommended command order

R-4 Recommended Command Order
Recommended Command Order
Because some command results change based on the settings made with other
commands, you should send commands and data in the order described in this
section.
Once you set the printing area and page length, send data line by line from top to
bottom of each page. The printer can handle data most efficiently when received
in this order (although commands can move the vertical print position both up
and down on a page). The exception to this rule is when printing bit-image
graphics and characters on the same line, as described in “Mixing text and bit-
image graphics.”
The following order is applicable to all ESC/P levels.
1. Send an ESC @ command to initialize the printer.
2. Set the unit of line spacing to the minimum vertical increment necessary.
3. Set the printing area.
4. Assign character tables to each of the four active tables as necessary (ESC/P 2
printers only).
5. Define any user-defined characters.
6. Select the font.
7. Set supporting features.
8. Set the print position.
9. Send one line’s print data.
10. End the line of data with a CR and LF command.
11. Repeat steps 6 to 10 as necessary for each following line on the page.
12. End the page with a FF command.
13. Repeat steps 6 to 12 as necessary for each following page (always send a FF
command after the final page also).
14. End printing by sending the ESC @ command.
See the following sections in this chapter for additional information on the above
steps.
