PQ-8P, PQ-8S

The PQ-8 implements the LAC command by taking the dot pattern received from the twinax host and then printing that exact dot pattern using the printer’s APA bit-image graphics at high-density 240 dots/inch. This permits the printer to print APF and BGU graphic output using exactly the same spacing as the IBM 4214/5224/5225 printers.

5.14.6TRUNCATE/WRAP

For normal or wide paper (14 7/8" wide) printing, select Wrap through Host/PC download command 26 or the setup software. This allows printing to extend the full width of the wide paper. The printer wraps printing beyond the margin to the next line on narrow paper when it is configured for narrow paper.

When using narrow paper (8 1/2" wide), you can also select Truncate. This ignores any printing beyond 8". Documents must be formatted to fit the narrow paper, since the text beyond an 8" margin will truncate (not print).

5.14.7 TRUE 15 CPI

Epson 9-pin printers, IBM Proprinters, and similar printers do not have the capability to print at 15 CPI. When the host sends a 15 CPI command, the PQ-8 is able to produce an “artificial” 15 CPI on the printer. This is accomplished by printing 17.1 CPI and adjusting for the spacing difference. In this manner, 15 CPI fonts sent from the host can fit on preprinted forms that must align correctly.

When using the Epson 9-pin printer driver, this is done automatically. Since the Epson DFX 5000+ is able to print 15 CPI, make sure to select the Epson DFX+ driver when operating the DFX 5000+ printer.

When using the IBM Proprinter driver, the user may manually select whether 15 CPI host commands should simply be printed as 17.1 CPI, or as 17.1 CPI with space adjustments (see Host/PC download command 28). Printing the “artificial” 15 CPI through the IBM Proprinter driver significantly reduces print speed.
