That are physical limitations and they can't be overrided. So, for page of 164pt we have, first, 14pt left margin, then 136pt of printing area and finally 14pt of right margin. In terms of points (1pt = 1/72in) paper of 58mm is has 164.4pt width, printing area of 48mm is 136. Calculating from pix/mm to DPI gives you about 203 DPI (as 25.4mm/in * 8px/mm = 203.2 DPI ). Dimensionsĥ8mm printer typically has 384 active pixels, placed in row of 48mm length. That is different from previous approach where each time PPD was parsed for them. Print settings are passed and stored inside a print job, in each page header. (also you can customize it by your own values without need to recompile the filter). Filter extracts the value and that is how 58-mm is different from 80-mm. ModelNumber from PPD contains number of pixels of printer's head. When printing driver checks every raster line if it is purely empty - and if so, uses 'feed' command instead of actual raster printing. Printer initialized by 'ESC Cutter works by 'GS V \1'.printing piece of 20mm on a paper 58x210mm will print only actually used 20mm and skip the rest huge tail. Skip blank tail if you print a small piece of data on a big roll - filter can determine the empty 'tail' of your printing and avoid to feed an extra paper. Length of the impulses to drive drawers may be customized.īlank feeds: after printed job, or after every page paper may be rolled for extra 3-45mm with step 3mm Supported 2 Cash drawers each may be opened either before, either after a whole print job. If available, may be invoked either after every page, either after the whole job. Originally it was reverse-engineered filter for Zijiang zj-58 with it's specific PPD,īut later it is revealed that it actually works with many other cheap 58mm printers, likeĬutter. CUPS filter for cheap thermal receipt printers as Zijiang ZJ-58, XPrinter XP-58, JZ-80 with cutter, Epson TM-T20, and may be any other printers understanding ESC/POS commands.
