The LaserWriter Select 310 uses PostScript and PCL4 for printing. The hex codes the programmer wants are probably the PCL4 escape sequences. Escape sequences are typically used with PCL or dot matrix printers.
Where to Find PCL4 Escape Sequences
-----------------------------------
* The User's Guide for the Select 310 has some information.
* Numerous books available for programming LaserWriters and
Hewlett-Packard printers, which we emulate via PCL4.
*â•©Hewlett-Packard publishes a manual for programming in PCL
Another option available to the programmer is to use PostScript instead of PCL.
