# ASCII Photobooth printer configuration # Sourced by txt2printr.sh and photobooth.py. # Is the printer loaded with A4 paper for a landscape printout? (true/false) # 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 # The Epson DFX-5000+ is a wide-carriage tractor-feed printer that only # takes continuous (fanfold) paper 4-16 in (101-406.4mm) wide - it has no # A4 sheet path, so this stays false. PRINTER_A4=false # Your printer's real per-page capacity in the normal (portrait, unrotated) # orientation, used to size the A4 viewfinder above and to know when a print # 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). # # The DFX-5000+ is fed from continuous fanfold stock rather than cut # sheets, so it's treated the same as a roll printer here (0). Its DIP # switches 3-1/3-2 do let it track a fixed page length (11in, 12in, 8.5in, # or 70/6in) with perforation-skip (switch 3-3), but that's a page-break # convenience on the paper feed, not a limit on total printable length - # re-measure with pagetest.sh if you rely on perforation-skip and want # output to stop short of the next perforation instead of running past it. # See epson5kp-dipsettings.md for the recommended DIP positions. # # PRINTER_MAX_COLS below is the datasheet's rated printable-column count # at the printer's default pitch (10 cpi) on its widest supported stock # (16 in fanfold): 136 columns. That's the printer's own printable-area # limit (0.51-1.22 in left margin, 0.51 in right margin), not a # measurement against this install's actual loaded paper width - # re-measure with pagetest.sh if narrower stock is loaded. # Source: Epson DFX-5000+ Product Information sheet (3/15/94), "Printable # columns" table.
