The printers use a 40-micron nozzle that outputs more than 100,000 drops per second of ink. While these printers make microprinting faster and easier to produce digitally, they still have not reached the true sub-pixel size of less than 1 point. [11] The smallest scale microtext a laser printer can produce is 0.5 pt. [12]
Struck through text by writing dash characters at the desired positions after writing the text to be struck through. Instructing the printer to skip to a channel which is not punched will cause the printer to continue to feed paper at high speed. This might be caused by a mismatch between the tape installed and the one the application expects.

In letterpress printing, individual letters and punctuation marks were cast on small metal blocks, known as "sorts," and then arranged to form the text for a page. The size of the type was determined by the size of the character on the face of the sort. A compositor would need to physically swap out the sorts for a different size to change the ...
In computers, a printer driver or a print processor is a piece of software on a computer that converts the data to be printed to a format that a printer can understand. The purpose of printer drivers is to allow applications to do printing without being aware of the technical details of each printer model.
The PPD can describe allowable paper sizes, memory configurations, the minimum font set for the printer, and even specify a tree-based user interface for printer-specific configuration. A PPD is also often called PostScript Page Description instead of Printer Description , this is because PostScript has the concept of Page Devices where the ...
