# Needle/dot-matrix printers have no hardware page-rotation command: the

# print head only scans across a fixed carriage width while the paper feeds
|
|
# in one fixed direction, so there is no way to make the physical page
|
|
# itself "landscape". Instead, when this is true:
|
|
# - txt2printr.sh rotates the ascii art 90 degrees in software before
|
|
# sending it to the printer (turn the printed page 90 degrees to read it)
|
|
# - photobooth.py sizes its live-preview viewfinder to an A4-landscape
|
|
# character grid instead of just following the terminal size, so what you
|
|
# see in the preview matches the shape of what gets printed
|

|
|
# job already fills the page (see txt2printr.sh). Paper geometry and stated
|
|
# pitch don't reliably predict this - measure it directly with pagetest.sh:
|
|
# ./pagetest.sh && PRINTER_A4=false ./txt2printr.sh pagetest.txt
|
|
# then read off the last line number on page 1 (-> PRINTER_MAX_LINES) and
|
|
# how many characters of the 64-wide test lines actually printed before
|
|
# being cut off (-> PRINTER_MAX_COLS).

|
|
# Set PRINTER_MAX_LINES=0 for a roll/continuous-feed printer that has no
|
|
# fixed page length. In that mode photobooth.py sizes captures to fill
|
|
# PRINTER_MAX_COLS width and lets height follow the image's own aspect
|
|
# ratio instead of cropping to a row count, and txt2printr.sh always feeds
|

# the paper out at the end of a print instead of skipping the feed when a
|
|
# page is already full (there's no page to fill).
