Receipt content is blurry on SP700 #17

Hi, one of our clients reported to us that their receipt content is blurry. It only occurs to our app since their printer works fine on Clover system. image

@nguyen-vo looks to me like it might be time to replace the ink ribbon. Do you know when the last time it was changed?

@gare-bear Hi thanks for replying. I don't know when the ink ribbon was replaced. But from what my client described, the print works just fine with other system

@nguyen-vo how are you generating the receipt? is the job a bitmap or plain text? can you show a comparison between the two?

nguyen-vo commented 3 years ago

first I generate the text and then pass it in the command method. I attach my code below Screen Shot 2021-07-16 at 2 22 34 PM

@nguyen-vo thanks for sharing your code. You're printing text which is the preferred approach for our Dot Matrix printers since they have a lower DPI compared to our Thermals.

I'd suggest adding styleBold to your PrinterBuilder, see if that changes the end result.

I'd need a copy of of the other receipt for comparison but I honestly think changing the ribbon will fix the issue.

@gare-bear thanks for your assist:D. I will try that
