java - More lines for customer pole display -


i looking pointers on can change number of lines on pos display in unicenta opos.

i managed figure out how stop sending esc data can show on 20x4 lcd hooked arduino can't figure out how accept 4 lines instead of standard two.

so uses top line , line 3. 2 , 4 stay blank.

display.write(trans.transstring(deviceticket.alignleft(m_displaylines.getline1(), 20))); display.write(trans.transstring(deviceticket.alignleft(m_displaylines.getline2(), 20)));

this standard in .java file , works.

display.write(trans.transstring(deviceticket.alignleft(m_displaylines.getline3(), 20))); display.write(trans.transstring(deviceticket.alignleft(m_displaylines.getline4(), 20)));

these want add give me headache , need figure out gets data from.

entire original code can found here: devicedisplaysurepos.java
