Mini Thermal Printer - Printing slow and Faded

Post by acretcher »

I'm having trouble getting my mini thermal printer to print properly after I have set up CUPS on my Raspberry Pi. If I print directly to the serial port using

Code: Select all

echo -e "print directly to serial port\\n\\n\\n" > /dev/serial0
it prints fine, as well as if I hold the feed button upon power up. However, when I use CUPS to print using

Code: Select all

echo "print from terminal using CUPS" | lp
or if I print from a word processor it prints about ten times slower, and very faint printing. I have good power (9V, plenty of A), I've been through this tutorial https://learn.adafruit.com/networked-th ... pberry-pi/ I'm not sure if it is a font problem or CUPS problem. Any Help would be appreciated!
