by Yohan Naftali 0 Comments

I found it’s tricky in printing Epson’s receipt printer font (TM-U220) on web browser point of sale application, CSS does not allowed me to access Epson’s receipt printer font. All you need to do is setting font substitution in printing preferences.

  1. Open Control Panel to access Printers
  2. On Epson’s Receipt Printer do right click then select Printing Preferences
  3. Select Tab Printer Settings
  4. On True Type Font Substitution choose Substitute options
  5. Click Advanced Setting to configure font substitution, or simply choose substitute all
  6. Choose Machine Font that you like (e.g FontB)
  7. Test Print and do trial and error ’till you get what you want

These steps are my best solution so far, do you have better/simple solutions to printing using machine Receipt Printer on web based Point of Sale applications? Tell me.

Konsep Pemrograman MVC (Model View Controller)

by Yohan Naftali 3 Comments

MVC adalah sebuah bentuk pemrograman yang memisahkan berdasarkan logika penanganan tampilan, logika pengontrolan dan logika model. MVC bertujuan supaya pada pengembangan perangkat lunak yang besar mudah untuk dilakukan maintenance (perbaikan/penambahan atau pengurangan code).

Model adalah komponen yang berfungsi mengambil data dari database/sumber data. Fungsi yang terdapat dalam Model akan dipanggil oleh Controller.

View adalah komponen yang berfungsi menyajikan tampilan kepada user. View menampilkan data yang diperoleh Controller.

Controller adalah komponen yang berfungsi untuk memanggil fungsi yang ada di dalam Model dan mengirim hasilnya melalui View, Controller juga berfungsi mengambil input dari user yang selanjutnya akan diolah oleh Model.
