Updated Code; Duplex, Simplex

[QORTEC]

Duplex, Simplex

The following code explicitly sets the duplex/simplex in PCL.

if (page_params_.duplex || page_params_.tumble) {
    fputs("\033&l2S", out_);
  } else {
    fputs("\033&l0S", out_);
  }

\033&l2S: This sets the printer to duplex printing with tumble mode.
\033&l1S: This sets the printer to duplex printing without tumble mode. (Not Used)
\033&l0S: This sets the printer to simplex (single-sided) printing.

#169 explicitly sets the printer in simplex mode (\033&l0S).
This resolves the issue of printers continuing to duplex when disabled.

QORTEC#2 adds duplex no tumble printing.

Toner Density

Owl-Maintain#12 adds toner density adjustment

1200dpi

The following code explicitly sets the 1200dpi mode.

  // brlaser.drv.in
  Option Resolution PickOne AnySetup 10
    // Choice "300dpi/300 DPI" "<</HWResolution[300 300]/cupsColorSpace 3/cupsBitsPerColor 1/cupsRowCount 0/cupsRowFeed 0/cupsRowStep 0>>setpagedevice"
    *Choice "600dpi/600 DPI" "<</HWResolution[600 600]/cupsColorSpace 3/cupsBitsPerColor 1/cupsRowCount 0/cupsRowFeed 0/cupsRowStep 0>>setpagedevice"
    Choice "1200dpi/1200 DPI" "<</HWResolution[1200 1200]/cupsColorSpace 3/cupsBitsPerColor 1/cupsRowCount 0/cupsRowFeed 0/cupsRowStep 0>>setpagedevice"
    Choice "1200x600dpi/HD1200A" "<</HWResolution[1200 1200]/cupsColorSpace 3/cupsBitsPerColor 1/cupsRowCount 0/cupsRowFeed 0/cupsRowStep 0/cupsInteger12 2>>setpagedevice"
    Choice "2400x600dpi/HD1200B" "<</HWResolution[1200 1200]/cupsColorSpace 3/cupsBitsPerColor 1/cupsRowCount 0/cupsRowFeed 0/cupsRowStep 0/cupsInteger12 1>>setpagedevice"

  // main.cc
  p.page_speed = header.cupsInteger[12];
  p.ras1200 = (p.resolution == 1200 && p.page_speed == 2);

  // job.cc
  if (page_params_.ras1200) {
    fprintf(out_, "@PJL SET RAS1200MODE = TRUE\n");
    fprintf(out_, "@PJL SET RESOLUTION = 600\n");
  } else {
    fprintf(out_, "@PJL SET RAS1200MODE = FALSE\n");
    fprintf(out_, "@PJL SET RESOLUTION = %d\n",
            page_params_.resolution);
    if (page_params_.resolution == 1200) {
      fprintf(out_, "@PJL SET PAPERFEEDSPEED = %s\n",
              page_params_.page_speed ? "FULL" : "HALF");
    }

  // PCL Section
  fprintf(out_, "\033&u%dD",
          page_params_.resolution);
  fprintf(out_, "\033*t%dR",
          page_params_.ras1200 ? 600 : page_params_.resolution);

Brother uses multiple 1200‑dpi modes across its printers:

• 1200dpi – a true 1200 × 1200 resolution
• HQ1200A – simulates 1200 dpi by printing at 1200 × 600
• HQ1200B – simulates 1200 dpi by printing at 2400 × 600

Compiling

QORTEC#3 fixes building on Fedora 38;
error: 'uint8_t' was not declared in this scope
Resolves , so uint8_t undeclared issue by explicitly including cstdint in test/tempfile.h.

Owl-Maintain#43 fixes building with CMake 4.0
Compatibility with CMake < 3.5 has been removed from CMake.
