These should work on most DMPs especially EPSON ones.\nBasically there are 3 font sizes built into the printer firmware.<\/p>\n
1) Normal size<\/p>\n
2) Large size – Use chr(14)<\/p>\n
Eg; Print #1, chr(14); “ABCDE”<\/p>\n
Will print ABCDE in large sized font. To revert back to normal size you can use chr(18)<\/p>\n
Eg; Print #1, chr(14); “ABCDE”; chr(18); “XYZ”<\/p>\n
Will print ABCDE in large sized font and XYZ in normal sized font.<\/p>\n
3) Condensed – Use chr(15)<\/p>\n
Eg; Print #1, chr(15); “ABCDE”<\/p>\n
Will print ABCDE in condensed font. To revert back to normal size you can use chr(18)<\/p>\n
Eg; Print #1, chr(15); “ABCDE”; chr(18); “XYZ”<\/p>\n
Will print ABCDE in condensed font and XYZ in normal sized font.<\/p>\n
This is all that I know.<\/p>\n
Regarding pagesize, there are specific codes. These may be found in the Printer manual.<\/p>\n
As far as I am concerned, in the progrmme I count the number of lines and send a page eject (chr(12)) when required. For example if the length of paper is 12″ and you are printing @ 6 lines per inch with 1″ margin on top and bottom, you can print 60 line on a sheet. After 60 lines you give a page eject to start the new page.<\/p>\n
1. How can i give blank line between lines ? (IF i need one blank line)<\/strong><\/p>\n Print #1, vbnewline<\/p>\n 2. Suppose my paper width is 9 inches, How many characters to be printed in one line ? (horizontal line)<\/strong><\/p>\n Depends on the font size. Normally it is 10 cpi. So after leaving 1 inch margin on left and right it will be 7*10 = 70 characters.<\/p>","protected":false},"excerpt":{"rendered":" These should work on most DMPs especially EPSON ones.
