pdf - PHP / Printer - Print out of line is aliased or dottedGet the solution ↓↓↓
I have an application allow user to do online signature using html5 canavas, and the image is in png format.
When the image looks in desktop, it is okay even zoom in and out.
But when printout, the line become alias or dotted. The application will resize the image, and stamp on a PDF, and then the stamped PDF will be printed out.
I tried adjust the printer setting to be 1200dpi, but it doesnt help. I am quite confused which part is causing the issue. May I know how should I make the print out more fined, or not less aliased under normal physical viewing?
