Track width nr 5 = 1,32 mm. Pad width nr 12 = outside 2,28 / inside 0,69 mm but outside size must change to 2,17 mm because of pad to pad is too close for me and the PSU / Spectrum Analyzer but design rule 10 thou (0,254 mm) check reported "no violation found" for 2,28. Pad width nr 13 = outside 3,55 / inside 0,90 mm.

A slight ovality occurs with printer type 24 pin. Extrem ovality occurs with printer type 9 pin = unusable. Printer type laser gives no paper output from HP LaserJet P1102.

Thank!!! you https://copilot.microsoft.com/chats/ for all information. Maybe the problem "A slight ovality occurs with printer type 24 pin" has the solution changing the height and width in DOSBox-X configuration tool printer from height 110 to hight 117 and from width 85 to width 83. A4 = 8,3 (8,27) x 11,7 (11,69) inch = 210 mm x 297 mm.
