i'm creating web app using java,and 1 of tasks print report customer.the problem paper design made , putted in actual printer , must fill blank fields.the questions :
1) how can print values in fields ?
2) there way simulate process without having physical printer, using virtual printer , upload default page ?

i attached part of paper in printer , should fill blank fields data comes jsf page.

enter image description here

i solved problem yours in past. company has pre-designed printed invoice. task put data blanks in place. in experience, should:

  • scan paper image same size physical version.
  • measure distance blank another.
  • specify location of blanks output data based on measurement.
  • you can use digitalized version background of output page , test on it.
  • try put first blank in place.
  • test , adjust code.

hope helps.
