I like using a2ps for printing document sometimes because it's easy to have n-up, can use nice headers, formatting etc.
But - if I try to print a pdf using "a2ps myfile.pdf" then it print out on the printer in very very poor quality, ie all extremely pixellated.
If I use the -o option and output to a file instead then I can open the file in gv and it looks ok (ie, the detail is there if I zoom in), it just seems to fall on it's ass when I try to print the output.
I am using an Epson R285 printer with the gutenprint driver.
When printing, cups displays the following message in the web interface:
"Gutenprint detected a bad color depth (1). Output quality is degraded. Are you using psnup or non-ADSC PostScript?"
