The application is coded on Visual Basic. It generate invoices from an Oracle DataBase. OS: Seven Proffesional 64 bit. If you print the invoice on black n white runs perfect. As soon as you choose color printing, the circle of wait appears for about 1:12 mins and then release the print.
I tried every available driver for this unit (global, mobile, pcl 1-6, ps) and no better results on any of them. I decided then to use a different printer, a phaser 6125 and balck n white and color prints fast.
Any suggestions to make the 7428 prints with no issues in color?
I am also curious to see if this resovles the issue. Please reply if that fixed your problem.
