The third illegal printing-office in Gorenjska (The Upland of Slovenia) was called »DONAS« by the partisan printers, after the constructor of two printing-presses for the partisan printing-offices in Gorenjska, Edo Bregar (whose partisan surname was »Don«), and Ms fellow-worker Nasta Sesek: the syllables »Don« and »Nas« joined gave »Donas«. This printing-office started working August 20 * 1944. A bunker was built for it in the Ločnica valley near Medvode in Gorenjska, not far from another illegal printing-office, »Trilotf«. For the printing-office »Donas« the printing-press was also constructed by Edo Bregar-Don, a technician, who was the manager of this printery for the whole time of its illegal functioning. The machine was rather big, having been built for the printing of periodicals and other large-sized (folio) publications. This machine was technically more complete than the one in the »Trilof« printing-office, since it had even an automatic inking-roller, and it weighed about 550 kg. as a whole. On this printing-press the partisan printers of »Donas« printed the periodical »Gorenjski glas« (»The Voice of the Upland« — the organ of the Front of Liberation in Gorenjska), various brochures, large-sized posters and pamphlets, and a series of other printed material, fairly well-finished and furnished: many prints also from this illegal press were finished in polychromy.

Bibliografija narodnoosvobodilnega tiska je izredno bogata. Napisanih je že vrsta člankov in razprav, ki na kakršen koli način osvetljujejo dobo narodnoosvobodilnega gibanja tako iz vojaškega kakor tudi iz političnega vidika, ter so dragocen doprinos za zgodovino te dobe, posebno za prvo obdobje, za katero Centralne partizanske tiskarne na Dolenjskem niso mogle zadostiti vseh potreb slovenskega ozemlja s centralnimi časopisi. Zato so razne pokrajinske ciklostilne tehnike te časopise ponatiskovale. Da bi se tudi v tem pogledu zboljšalo stanje na Gorenjskem, je Oblastni komite KPS za Gorenjsko že v tistem času, ko Edo Bregar-Don še ni dokončno izdelal tiskarskega stroja za tiskarno »Trilof«, izrazil željo, da bi Don izdelal še en tiskarski stroj večjega formata za tiskanje časopisov
